3 rounds of virtual interview. 1st is HR screening, 2nd interview with hiring manager and 5 other team members in panel, 3rd is a 2 day interview with 45 minute presentation and Q & A then 6 panel interview. Day 2 continuation of round 3 of 6 more panels. Round 3 is mostly senior leadership team and a few scientists. Very exhausting but they were all very professional, kind, and gave me a positive impression of the company. I asked them hard management and leadership questions to find red flags. They all past my interview test.
