Power day consists of two technical (semantic, ontology modeling on a white board, sparql) and one behavioral interview. One thing I didn't do was take control of the interview when it seemed to be lackluster on the interviewer side. I was waiting for cues, but that wasn't effective.

There were 4 rounds of interviews: a phone screen with a recruiter, a virtual job try-out, an interview with the hiring manager, and then a power day (3 interviews: 2 technical and one behavioral).
