TLDR: Complete disrespect for developers' time - DO NOT apply here! Hadn't heard of the company before their recruiter approached me out of the blue. Seemed interesting enough so I attended the interview and answered their questions (many of which were essentially technical questions) and asked a few of my own to get a sense of the company. I thought things were mostly going well, especially in the second half of the interview. Of course, I also noticed that they'd suddenly posted the previously unadvertised job on LinkedIn a few hours after my interview (which, in retrospect, was extremely rude). Then a few days later I received an email from the interviewer saying that they'd decided to move forward with other candidates but without saying why. About two months later, it looked like they were still recruiting for the same position so I asked if they had any feedback regarding my own interview. They flat-out refused to give any. Apparently they don't provide feedback as a policy. It was totally disrespectful in my view and really gave a bad impression of the company culture. Furthermore, given that it's not uncommon these days for tech companies to advertise job listings for roles that don't exist (e.g., in order to fool investors or internal staff), it does call into question whether they were serious about hiring anyone at all.
