First interview was with department lead. Second interview was meeting the rest of the team, which was very helpful. Third interview was with the regional leader, which was extremely uncomfortable for reasons explained later. Fourth time to the office was to complete the industrial psychology assessment. Shall I go on? Ah, yes. You also take 3 hours of online assessments and hold a 1-hour call with the industrial psychologist. In a nutshell, the company has an extensive and slow interview process. It is unfortunate that potential candidates meet with the non-engineer regional leader who vehemently touts that he "will" be the next CEO and then continues to only describe himself and his accomplishments. He showed no interest in the interview process other than the interest he took in himself. Narcissistic bosses are not uncommon but usually are capable of not exhibiting narcissistic traits during the interview. Not this one. I heard he does this often in many other interviews as well so it was a relief to find out that I wasn't the only soul that endured the self-proclaimed rant. And to respond to the next section of interview questions. For the third interview, no questions were asked - it was simply a soliloquy by the regional leader, where you're the mirror on the bathroom wall. The 1-hour phone call with the industrial psychologist included numerous repeated questions so be prepared as consistency is part of what the industrial psychologist was observing.
