Submitted my resume on their website and one of the engineers contacted me by email. We schedule a call but on the day of, he never called. I emailed him asking if we were going to conduct the call and he calls me 30 minutes later. The guy was pretty unprofessional over the phone but I still felt I should continue the interview process because why not. He tells me I have to come in for a 2 hour coding assessment (which I see differed from most people here on GlassDoor). I said okay and he tells me I should expect HR to call me. HR calls me and I tell them my availability. They say that's fine and they'll send me an email to confirm everything. Next week comes and no email ever came. So I email the guy again and he tells me I am suppose to come on one of the days of the week (note: I told them my availability but to have to find out exactly which day works for them and I by having to email the engineer is another unprofessional move. I really should have read this as a red flag). HR sends me the email later. On the day of, I show up to the company headquarter. An HR representative greets me and was very accommodating. I get led to this room and then the engineer I was talking to on the phone shows up with a laptop for me to perform the challenge. He leaves me with the laptop to do the challenge for 2 hours and tells me he'll be back in 1 hour. He never comes back and I finish the 4 questions they give me on this dinky ThinkPad. 2Hour and 30 minutes later and finally I call him on their company phone. He says "Oh" on the other end of the line and then comes in. He continues to go through my code and then begins to lambast me over minor details. Here is the part where I get pretty frustrated. Sure, maybe I am technically "challenged" but there were aspects of his explanation that made me think this guy's coding style was archaic and stubborn. Whether it was a refusal to embrace OOP or just the way he explained things was very off putting. Having gone through other interviews with other companies, I was unready for such a refusal to accept that engineering at its core is to embrace change and have ability to review your mistakes. After the end of this session, I almost wanted to walk right out of the interview. For professionalism's sake, I did not. I was then interviewed by 3 more engineers. My second interviewer was actually a decent and friendly person. I felt more relaxed around him and was able to go over basic concepts with him. Shoutout to this guy. We talked about some basic OS concepts and then he had me do a programming question on the whiteboard. Third interviewer was also not bad but given what happened with the last hours, I was pretty tired and ready to stop. The final interviewer was just as bad as the first one. He mumbled a lot while asking me question and by this time I was ready to call it quits. He asked if I had anything to ask him and I asked him what brought him to this company. He said he was there because the company was private during the economy and he wanted to make money. By then I kind of understood the company culture. It's past the end of the work day and I was ready to head out. Talking to the interviewers gave me a sense of what kind of company it was and I realized it's definitely not for me. The company was founded by Asian founders and whether it's been successful or not but I could feel the application of Asian work life on its worker and the age its been displaying. I don't recommend applying for this company for anyone who wants to be able to do more with engineering and challenge themselves. Besides the second interviewer I talked to, it doesn't seem like any of these guys is capable of embracing change. I seriously started doubting myself as an engineer and everything I valued after this experience.
