Some programmming problems , not sure of what was the purpose .Squeezing all interviews in 2-3 days without any clarity of what or why this its happening. To top it of a half baked behavioral interview wasting everyones time and energy when it felt predtermined not to move forward. I think either they want to give practice for the interviewers or the shadowing person is interviewing the other guys abiltiy to interview i think.

2 behavioral rounds + 3 technical rounds including a code review round. Other than the code review part it was pretty normal. Good scheduling process, prompt and useful feedback after each round.
