The entire process was a waste of time and recruiter always seemed confused. I was invited for a recruiting event in their office at San Francisco. I was asked to take a coding challenge to put myself ahead from others before the recruiting event. It was a simple one, and I did it immediately. But at the recruiting event, I was not questioned anything about the challenge, neither did I have anyone to talk to about it. Instead, there was a workshop where we were asked on how we would design a web page, given some APIs. The discussion was good and I got good feedback from them immediately. Surprisingly, I was not contacted back about it for until a week, after which I emailed the recruiter. The recruiter then set me up for a phone interview with one of their engineers. It seemed like the interviewer did not know anything about my previous coding challenge or the workshop at their office. However, the interview went well and they sent me yet ANOTHER coding challenge and also set me up for an on-site interview. I was given an interview itinerary, so I submitted the coding challenge and went for the interview. Again, the process seemed very chaotic and none of the interviewers knew they were supposed to interview me, neither were they mentioned in my interview itinerary. The first interviewer pulled up my resume in front of me, reviewed it and started talking to me. The interviewer asked me to write a program, but was very silent throughout the time I was coding it on whiteboard. I was thinking out loud, but it felt like I was talking to the walls. Absolutely no feedback, whatsoever. I had good discussion with my next two interviewers. My last interview was supposed to be about my second coding challenge, which was cancelled. Funnily, the coding challenge was front-end project whereas the role was for back-end engineer. After two coding challenges, one workshop onsite and one phone interview, I did not except the on-site interview to be unprofessional.
