Software Engineering

Cost: $16,900
Duration: 15 weeks
Locations: NYC, Denver
In-person Only
Course Description:

Being a software engineer requires more than knowing how to code or build a web app. Over 15 challenging weeks on Flatiron School’s campus, students learn to think, and build, like software engineers — from developing coding proficiency to gaining an understanding of how products are designed and managed. In each three-week curriculum module, students develop key skills through interactive labs, lectures, and close collaboration, showcasing progress through Portfolio Projects. While the bulk of the material covered encompasses the Ruby and JavaScript ecosystems, we carefully designed our curriculum to prepare students to launch software engineering careers, independent of any specific language or technology.

The course covers Ruby, HTML & CSS, Object Orientation, Object Relational Mapping (ORM), SQL, Rack, Sinatra, Rails, JavaScript, React, Node.js and Express.js, Angular, and more. By the completion of the program, students have done much more than simply build technical skills: they have maintained technical blogs to show they can credibly talk tech; they have become a part of the tech community; they have amassed an impressive portfolio of unique, functional web applications to show employers as they enter the job-search phase with the support of our Career Services team.

No previous coding experience is required, but Flatiron School encourages all applicants to start learning through the free coding introductory lessons.. All students apply through a standardized process, including a written application, admissions interview, and technical review.

"The little engine that couldn't."

At face value, Flatiron's promises and guarantees (such as the money back guarantee) seem flawless. Flatiron seems like a reputable school with great values and, with hundreds of great reviews online, there's no reason to believe otherwise. But beware:... Read More

We were promised lead instructors and assistants.

Three days into the bootcamp, every single lead instructor on my campus quit. We were then taught by TAs that apologized for their lectures because they had, and I quote, "never taught before." Flatiron attempted to remedy the situation by flying in leads from DC and NYC, but neither instructor stayed longer than a week (a mod is 3 weeks) despite being told we would have them for a whole mod. This meant our TAs stepped in and taught a couple of lectures, while most of the time we were just sent pre-recorded lectures from the prior year. To add insult to injury, they finally hired someone named Lyn to come in and be our Lead Instructor for the last 3 weeks before our final project. She taught us one 30 minute lesson, "Who is Lyn?" and then was conveniently sick/caring for her sick wife for the rest of the three weeks.

In the event that you did not experience instructors leaving (which would be a miracle considering lead instructors are hard to come by these days), lead instructors are NOT what is promised on the website. Now, please don't think I'm calling out every lead instructor, there were a couple great ones, but one of the best ones quit 3 days into my first week.

Have you ever heard of code academy? Flatiron certainly has as it seems all of their curriculum is either poorly TA-written (and I mean, POORLY), or ripped off from code academy. The amount of times we looked around and scratched our heads at what on earth we were supposed to be doing is far too many to count. Sure, you might think we were just a particularly stupid group, but it turns out that most Alumni feel the same way about the curriculum.

Also, you cannot go from "beginner" to "job ready" upon graduation. You are not taught enough basic fundamentals (hello, react hooks?!?) to even get a jr. level job and far more people spend 6+ months after graduation absolutely grinding out lessons from places like code academy and leet code to get up to par that Flatiron would like you to believe. There is no curriculum after the 15 weeks (technically, it's only 12 because the last 3 weeks are spent working on a project) to further your education and you will find yourself scouring youtube videos on how to code just like you did while attending flatiron.

Job Assistance:
I've said it once and I'll say it a hundred times: I got a job despite going to Flatiron.
My previous work experience played a HUGE role in getting a job and Flatiron does NOT have a "robust employer pipeline" as their website would like you to believe. Their money back guarantee is also a scam. If you do not do every single thing they ask for 6 months (and the requirements are really, really tough) then you are disqualified from getting your money back. I think 2 people in the history of Flatiron have gotten their money back and I know of 8 in the last couple months that have tried.

We did not have "Lunch and Learn" meetups with people in the industry, I was not contacted by Employer Partnerships more than once regarding a job paying over $12/hr ($24,900/yr)... the going salary for a SE in NYC is $75,000/yr.

Flatiron has one silver lining. Their alumni community.

BUT, If you want to spend $15,000 on a bootcamp that barely gets your foot in the door, potentially rips you off for $20,000+ if you do an ISA, or screws you over by disqualifying you for a "Money Back Guarantee" that is nothing short of a legal scam, then go ahead, be my guest. But as for me? I do not recommend Flatiron. There's so many better options out there that are free.

"Flatiron School Web Development Self-Paced"

I did the self-paced boot camp. I was initially required to complete it within 15 months, but Flatiron School offered a three-month extension due to COVID-19. I would've dropped out otherwise because I found a full-time job that consumed most of my time... Read More

The technologies I learned are ruby, ruby on rails, Sinatra, HTML/CSS/Javascript, react, redux, and thunk.

The structure of the program is articles consisting of paragraphs explaining concepts. Those articles frequently have code samples and videos. It is written in the style of a blog, with many memes. (This boot camp is why I installed a meme blocker extension.) There are also many metaphors that explain difficult concepts. Overall, it's very accessible.

Outside of written lessons, there are code-alongs (coding exercises that supply the answers) and labs (coding exercises that don't supply the answers). Labs generally supply tests that must be made to pass, but the code-alongs might not.

There are also final projects. These are coding exercises that include a list of requirements that demonstrate knowledge of recently learned concepts. They are unstructured enough that Flatiron School doesn't supply tests, but the student can optionally write their own. The types of projects are: ruby command line interface, ruby with Sinatra web framework, ruby with rails framework, ruby with rails api and HTML/CSS/Javascript frontend, and ruby with rails api and react frontend. Students must submit a blog post and video explainer as part of the project.

Along with completing these, a student must schedule time to explain their code to an instructor. First, they must explain what it is and why they made it. Then, the student explains how the project meets all requirements, and then do some live coding.

There were really good options available for getting help. They included participating in chat or viewing a lab's repository. My experience of chatting to get help was that the person who responded (an instructor, I think) gave me hints about how to structure a method. I still didn't understand, so the instructor eventually gave me the answer.

I preferred not to have to start a chat to get help, so I dug around a little. I found that Flatiron School's repositories often had multiple branches. The Solution branch of repositories associated with labs offered me quick help that didn't require reaching out. And, obviously, being able to read code is a very different experience than someone telling me to incorporate a certain data structure. I think it would be good if Flatiron School advertised that solutions are available in their repositories, but I can see why they might not want to.

These help options aren't available for the final projects.

After formally graduating, I found that there is actually more content for studying. There is a section that discusses launching final projects live on the web, and there are explainers on data structures and algorithms. Finally, there is a list of algorithm problems to help a new graduate get used to solving new and unusual problems. My critique would've been that devops/live environment setup, algorithms, and performance were completely neglected, but the post-work section makes a good save on that front.

I found the self-paced program to be flexible. There is an unenforced expectation that students complete the material in order. For example, each final project is situated after material a student would've just learned. Instead of doing them in order, as full-time students are required to do to keep up with their group, I saved them all for the end. I also completed some final projects out of order. I even waited months to schedule an instructor review after indicating that I completed one of the projects. I also found a lab that could be done in a group. I was going to do it in a group, but after not visiting that page for a long time, I was somehow switched over to doing it on my own, so I just completed it alone.

I started looking for a job before completing the boot camp. That wasn't necessary because Flatiron School brings very promising prospects to graduates. Relying on Flatiron School's career services was the difference between recruiters constantly telling me they wanted experience and recruiters sending code challenges to see what I could do (often before a phone screen). It was also the difference between having to figure out where are jobs in industries I wanted to work in, versus jobs I was really interested in reaching out to me after deciding I'm a good candidate.

My career coach helped me create the job search I wanted. Historically, I've found work via cold calls on job posting sites, so I expected to go that route. She had ideas that were very different from what I wanted to do, but she was willing to help me stay within certain requirements to qualify for Flatiron School's career services. I'm not a fan of LinkedIn or showing pictures of myself online as a way of pursuing a job, so I was glad the only change we settled on was me adding my last job. Ultimately, outside of relying on Flatiron School's pool of prospective employees, I did find a job without relying on any networking lead-generation practices.

I also found Flatiron School's tools for finding a job to be very different from what I had used before. Although it was basically a spreadsheet and a word document, it allowed me to organize in a way that I didn't know the value of.

"Flatiron UX/UI Experience (I had to choose course as datascience because UX was not offered as an option)"

I'll give it you straight after going through the whole 6 month experience along with some of the after program career services track.

The first 2 phases or around 3 months was great. The instructors were knowledgeable and enthusiastic when it came to... Read More

So the first 2 phases went great, and I came in excited and bright-eyed for the in-person phases on the NYC campus. Now this is where the program goes downhill. While I did learn some new things about UX design and research, the instructors were not attentive or great at teaching. I understand the importance of repetition when it comes to the end-to-end design process, and I don't have a problem with it. Actually, I found it helpful that it was repetitive so we had the chance to use our skillset we learned from the previous phases and apply research/design methodologies that worked in specific situations. I also found the repetitive nature of weekly presentations to be helpful in a sense that we had more experience in creating slideshows and presenting.

Now comes the bad stuff. The most amount of design feedback anyone in my cohort received on our presentations and project was in phase 1 and 2. The instructors in the in-person phases would just deflect any relevant questions with "it depends". Of course, "IT DEPENDS". Students are asking because they are weighing out certain decisions within the project framework and asking for a seasoned designers opinion on it. I value autonomy, but at that point when everything triggers the same "it depends" response is, honestly, infuriating and condescending. It's more of an excuse not to do an instructors job. We are in a bootcamp and it's the safest place to fail there--but there was no guidance in any design choices through the in-person phases. The most amount of feedback we received were about the presentation slides and style. While, this is helpful, it's not the feedback we are solely looking for as designers--at a certain point, we don't care what you personally think about certain slides as long as the content is good (but no feedback really there so we will never know). Additionally, the attitudes of the instructors were unprofessional. Personally, I had no issues with any but a lot of my classmates in every cohort had problems with the attitude of most instructors. There was a very passive-aggressive cattiness that was directed at students and was not controlled in a professional, learning environment. Most of the time, the instructors came in later and left earlier than students.

I think the quality of instructors went way down after Flatiron purchased Designation and scaled up to many locations. Being a design instructor at Flatiron seems to be the easiest decent paying job ever. We were more micromanaged about student benefits that we expected to have but couldn't because of their process mess-ups. The programs conflict resolution was a joke and their student selection measures and support were also laughable. I've seen this in many cohorts as they ruined the experiences of many students by not selecting capable designers. Honestly, it makes sense that the organization got rid of the design program because if they wanted keep that program up, Flatiron really needed to look inward and make a lot of changes.

Now career services is iffy at best. The way Flatiron sells you their program is that they have 96% successful job rate after the program for it's students. First off, this is highly contestable as the numbers seem to high to be true. Also, they sell you that the school has a great (already) built-up network with employers to help with prospective job-looking alumni after they graduate. The iffy part of it is that covid definitely took a toll on their "network" so that is due to uncontrolled external circumstances. However, the coaching is subpar and the Money-Back-Guarantee is really a sham (don't enroll because you think you will get your money back--they will fight you tooth and nail on everything to not give you the money back). They have many organizational problems within their employment team which causes alumni to face negative consequences of their bad company management. The amount of employers they have in their "network" is seemingly 0 to few very unrelated positions--which is mind-blowing if they already had a great network before when advertising. And after all that, all they do is deflect responsibility at the alumni seeking jobs about personal accountability. I am telling you right now that job seeking alumni are doing everything they can do network and apply to get jobs because it's our career and our life, so make it seem like we are dropping the ball. For the $17k price point with the advertisement before enrollment, certain services are expected.

Overall, it is a bloated organization that does software engineering really well. But I would stay clear of their design programs if they relaunch in the future.

"Awesome option for a career-changer"

Overall, I had a fantastic experience with Flatiron School. The program enabled me to get a data science job that ticked all my boxes. I was able to make a dramatic career transition (during a pandemic, no less!) from academia/non-profits to tech thanks... Read More

Background: When I was applying to bootcamps, I already had a PhD (in a humanities discipline) and lots of data science and programming tutorials under my belt. I chose Flatiron School because the curriculum looked good, the program was only 5 months when done full-time, and they offered an income share agreement as a payment option.

Getting in: First I had a call with a representative to assess my interest and experience in data science. Then I got access to some preparatory materials that included basic Python and a little bit of calculus. Once these were done, I had a technical interview with a Flatiron School instructor, consisting of a few basic programming questions and a conversation about some math/calculus concepts. The preparatory materials were enough to help me be ready for this interview, but the real point of the interview is to assess whether you can learn quickly and take feedback/correction well. After this, I was accepted to the program and chose my start date.

The program: For the duration of the program, I had one instructor, an "educational coach" (to help with motivation, study skills, etc.) and a cohort of fellow bootcampers. We spent four hours per week in live lecture/office hours, and I had two half-hour one-on-ones with my instructor each week, too. My cohort had its own Slack channel where we could ask the instructor or each other questions and do daily standups. Here's a list of topics we covered (not exhaustive):

General Python programming, with particular focus on NumPy, Pandas, and Matplotlib
Git, GitHub, and principles of version control
Basics of data visualization
Regression (linear, logistic, multiple linear, polynomial, etc.)
SQL and general principles of database design
Basics of object-oriented programming
APIs, web scraping, and working with JSON files
A broad survey of statistical topics, including combinatorics, permutations, distributions, central limit theorem, hypothesis testing, and Bayesian stats
Time series analysis
Basics of linear algebra
Survey of machine learning algorithms and techniques, including k nearest neighbors, decision trees, random forests and other ensemble methods, support vector machines, PCA, k means, and recommendation systems
A little introduction to Spark via PySpark
Basics of graph theory/network analysis
Basics of NLP
Survey of deep learning topics, including RNNs, CNNs, and transfer learning
A little intro to AWS and how to deploy a machine learning algorithm into production.

Near the end of the program, I also got access to a career prep curriculum, which contained readings and exercises relating to résumés, LinkedIn, networking, building a professional web presence, etc. Flatiron School recently added a post-bootcamp curriculum of extra stuff to study while job-searching, including more work with SQL, and intro to R, and some guidelines for making your projects look better on GitHub. I'm really glad they created these additional resources, since these are things I went out and studied on my own because they were important for my job search. Flatiron is constantly updating the curriculum, and students are welcome to submit suggestions or corrections to be addressed by the curriculum team.

An average day of bootcamp involved a lot of independent reading and work on the labs provided in the curriculum, interrupted by a lecture/group meeting with instructor and classmates to go over the material assigned for that day. This format was great for me because I learn better when I can focus on something on my own for a while and then have a chance to ask my questions and hear other people's questions, too. Each day's meeting covered a certain chunk of the curriculum, but there was a lot of flexibility to work ahead or take more time on something if I wanted. Although you could always spend more time on things, I found it was possible to complete each week's material to my own satisfaction in 40-45 hours on average.

Overall, the curriculum prepared me well for my job search. The projects I built during bootcamp were of a high enough quality that I could present them during job interviews. The capstone project is totally open-ended, so you can design it to show off skills relevant to the types of jobs that appeal to you. For each project, I had to do both a non-technical presentation and a code review with my instructor, and these experiences were extremely helpful once I started looking for a job. This is definitely one of the reasons to do a bootcamp rather than just studying on one's own. If someone I knew were looking for a bootcamp today, I would tell them to ask whether a program includes this kind of project work, since it's the best way to prepare for/show that you're prepared for real data science work.

Career services: My experience with career services at Flatiron definitely made the program worth the cost. As soon as I graduated, I started working with a career coach who helped me with my résumé, mock interviews, web presence, and general job search strategy. My coach was amazing, especially at keeping me motivated when the pandemic brought my job search to a screeching halt. It was really helpful to have someone to talk to each week about my job search, and she was super responsive to any questions I had about how to respond to e-mails, networking tactics, etc.

Highlights: The best parts of the bootcamp for me were my instructor, my career coach, and the projects I built.

Improvements: I would have liked to see a little more space in the curriculum given to ethics, maybe some case studies about practical applications of data ethics. There was a brief overview of data ethics in theory ("Hey, you should only make ethical use of people's personal information! There is bias in AI!"), but since this is an issue that affects all aspects of data science, it would be good to give it a little more weight.
