I have had some sad rejections over the years. I remember one company rejected me a few months ago for not knowing enough algorithm/data structure knowledge - I subsequently passed interviews with two teams at my current employer, one of the famous big tech companies. I had a startup pass on me as well that prior job search for reasons unknown even after acing their interview. I found out only 2-3 weeks after interviewing, and I think they’re still trying to hire for the position (it uses Angular 1 - I also happen to probably be still one of the most knowledgable people about Angular 1 outside of Google). I got insight into one company’s interview process after doing a take home project, and one person mistakenly replying to all with me in the email chain - the person didn’t think highly of my work on it, despite that I only spent 4 hours (the time I could spare on it) and kept clean abstractions, setup, and accomplished the main point of the take home project. That experience cemented to me that take home projects are a race to the bottom with it being necessary to spend an extraordinary amount of time and little reward back. Amazon ghosted me while we were in the process of setting up onsites in San Francisco and we were taking about compensation in parallel (they started the comp conversation) - I’m pretty sure they did so after a few back and forths due to not being willing to bend on comp numbers. I still get emails from recruiters about 10 times a year from them. I’m sure I’ve had others, pretty sure most people who’ve been in the industry for a while gets them if they have interviewed around.
