After passing several lower-level interviews, they gave me a take-home coding challenge and I was eager to show off my skills. They asked for a professional-grade product with an extensible API, lots of test coverage, and documentation. (The product itself had specifications that they gave.) I spent FIFTY HOURS creating a product that went far above and beyond what they asked for, all within the course of a week like they asked. (I also have an extensive portfolio with dozens of apps, so at this point I figured I was going for overkill.) I added extra features to help visualize the data; I created an interpreter for the language they asked me to write, which gave helpful hints when you had bugs in your code; I made the language easily extensible and streamlined the process by which you could add commands to its vocabulary; I made it easy to embed the app in a web page and modify its layout at will. The app itself was of a gorgeous design that I put no small amount of effort into. To support all of this, I wrote twenty pages of test coverage and sixteen pages of documentation. After all of this effort, they (1) told me they would get back to me a few days later, and were a whole week late on that, and (2) rejected my application while stating it was not their "policy" to tell me why I was being rejected. Well, it's not most company's "policy" to make people work fifty hours for free, so that should tell you a LOT about this company's toxic work culture.
