A recruiter reached out to me on a Friday night through email. Then he sent me another one early Monday since I couldn't get back to him (I was on a vacation over the weekend). I contacted him back, giving him my interest and he said that we will have a few days later. He didn't call on the date schedule so I emailed him again and we set up another meeting. He was late to call on the re-scheduled meeting because he was out having lunch or something and he called me while he was walking back to the office. We chatted for a couple of minutes about my experiences and something distracted him, which was when he said that he would call me back in 5 minutes. Never called me back, I sent him a friendly text message as a last reminder and then gave up. While there is a chance that I may have offended the recruiter (I can't recall any) in some way, him being late twice, having to reschedule, and ultimately forgetting/ignoring after pinging me twice within a few hours work hours (Friday night - Monday morning) is uncalled for. Of course, one person's attitude does not represent the whole company, I'm sure other interviewees may have a difference experience depending on who they get. Red flags that seems to me were: - Unorganized. Shows lack of guidelines or standards that the recruiters might follow. This is worrisome for the future because this can cause quiet a hectic when you start working. - Unappreciative of your time. I left my schedule open for it when I could have been doing something else. - Unfriendly/rude. I'd appreciate it if I got some kind of a response back saying I was declined or if the position was filled, not left ignored.

Interview process was a pretty typical phone screen, followed by on-site technical interview (approx. 4 hours) and on-site followup interview with non-technical team members (also approx. 4 hours). The technical interview was challenging but not ridiculous, focusing on data structure and system design fundamentals over detailed algorithm implementations.
