I went through three rounds of interviews for the role, which I feel is fairly standard for the industry. My issue was more in how everything was communicated and organized during that process:
1) Just prior to my second interview, while waiting for a calendar invitation, I was sent an email by the hiring manager asking if I was still prepared to meet within the next 15 minutes for round two, as I had not confirmed the invitation. Confused, I mentioned I had received no such invitation. After a flurry of internal communications on their side - I'm assuming - I was finally sent an invitation for a call the next day.
2) There was resistance in discussing compensation for the role at all times across all 3 interviews. Just before round 3, when I made an effort to proactively reach out to the first interviewer about it, I got zero response.
3) After the final interview, I was told I would receive an update by end of week. The following week, when I still hadn't received anything, I sent an email to each interviewer individually over the course of 2-3 days looking for answers. One of the final interviewers finally responded, saying that 'they had an interview rescheduled late' and I would receive an update at the end of THAT week. I never got an answer. I didn't even try to reach out at that point - they seemed so disorganized, I just wanted to be done with them.
