3 week, 3 rounds with HR, hiring manager and VP of group. Talked through prior experience and technical analysis. Negotiated compensation, start date and relocaiton with HR for a few days

What a waste of time and joke of an interview process. The recruiter was initially friendly about my experience and background, then turned hostile. The HM was clearly looking for something outside the scope of my background (focused way too much on a narrow scope of what they were looking for) which had already been vetted. Put it in the job description if you are only looking for experience in 1-2 specific things. They were rude and interrupted. A follow-up feedback survey was never sent even though one was supposed to be per their interview guidance. The HM didn’t care to ask any questions about culture (even though they send a whole packet about their culture) and hung up the call before I could even finish my final thought. Avoid like the plague.
