Behavioral

This interview process was really strange. The vibe was very arrogant, like they assumed everyone would want to join them just because they're in AI. The hiring manager asked questions that were very leading and seemed to expect exact answers, almost like they were trying to trick me into saying certain things. I'm not sure what kind of mind games were going on, but I decided not to continue with the process.

This was the most disorganized interview process I have ever been a part of. Email replies from recruiting were late or completely absent. In one case, a question about an interview session was responded to two days later, a full day after the session about which I had the question. In another, an email in which I was told to expect a reply in "30 to 45 minutes" was never responded to at all. It seemed that no one was communicating with anyone else. I had two "system design" sessions, and the person in the second session asked me the same question as the first because they had not done even the most basic coordination. The last person I talked to as part of the process asked me "am I the first person you've talked to?" Feedback was contradictory. I was originally told that I had done well on one portion of the interview, then in a following email, told that I had done poorly. Which was it? I was told to expect a final determination on my candidacy "Friday, or no later than Monday". I did not hear back until Tuesday afternoon. At that point I obviously knew not to expect good news, but that's the sort of thing I should hear from a person, and not have to infer from the silence. I will say that I enjoyed talking with everyone individually. People were friendly and (mostly) helpful. However, recruiting isn't just about having good people involved, but having a process that works and treats candidates with the attention and respect they deserve.

Coding System Design Presentation Behavioral

Applied and got contacted by the coordinator in the first week to set up a meeting with a manager. The second week, I had a nice chat with the manager about the job, team dynamics, and the interview process which includes coding, system design, presentation, and behavioral questions. They said the coordinator would reach out for scheduling. I didn't hear back in the third week, so I followed up, and they said they'd have updates soon. The coordinator finally got in touch in week 4 to set up interviews for the next week. On the morning of the interview in week 5, I got an email saying the role was filled and my interviews were canceled. While I get companies need to be selective, it felt unfair to fill the role while interviews were still scheduled. Also, canceling on the interview day itself was pretty inconsiderate, as that time could've been used more productively. The people I talked to were nice, so I assume the work environment is good, but the hiring process needs rethinking.

Technical Behavioral Presentation

So first there was this initial phone screen, then they gave me a take home assignment that was pretty easy. After that, I had a longer interview where I met with 5 people from the team. These interviews weren't really technical, more about seeing if I'd fit in and asking a few things about the take home. Then there was another take home, this one was much harder and took me basically a whole day to finish. The last interview was with the CTO, which also wasn't super technical, mostly about my interests and current projects. The whole thing took about a month, and then I actually started a month after that because of the holidays.
