I met with a panel, they prepared behavioral questions (HR provided them to the panel) so they are a fixed same questions they just pick 4-5 to ask you.
my interview lasted about and 1:15 min. time was flying, it was entertaining as the panel made sure I feel comfortable, I went over my resume for the most part.
And then I had another interview same week with CFO and SVP each took about 20 mins (different rooms, they were not together)
