Did not receive an email about starting the interview process until about ~4 weeks after applying to the position.
Process was standard. 30 minute Phone screening by one of the hiring managers, 10 minute call from HR about salary expectations, A take-home personality assessment, and a final 1.5 hour video interview with senior team members and both hiring managers.
Personally, I enjoyed the interview portion with the Senior team members more than the portion with the hiring managers. The senior team members would provide feedback on my answers and suggested additional troubleshooting steps on their scenario based questions. The hiring managers on the other hand seemed to be only "grilling" me with questions. Something that stood out to me was that one of the hiring managers seemed intent on getting me to second guess my responses. For instance, they responded with "really are you sure about that?", when they asked if I agreed with the result of my take-home personality assessment. Another time this behavior came up was after I gave my answers for a scenario based question. The same hiring manager would repeatedly ask me "Are you sure that's all you would do?", despite me affirming yes each time. They asked me this a total of 4 times and each time I confirmed that I could not think of anything else.
I haven't encountered this interviewing "tactic" in any previous interviews, but I'd like to give that hiring manager the benefit of the doubt and believe that they were not trying to come off as hostile. Perhaps they were just looking for different answers than the ones I had provided.
