3 interviews: 1st phone-screen was 15 minutes, 2nd interview was 4 parts (30 mins each) and more indepth. 3rd interviews was 1.5 hours included technical assessment and presentation + Q&A with a large group.

Began with a brief screening call, then a round of four 30-minute interviews and lastly an assignment which I had 24 hours to complete before presenting my work to an audience and then meeting the CEO. This entire process took about a month.
