Phone screen followed by 5 straight hours of 1:1 and 2:1 interviews. Heard back about the interviews the next day followed by an inquiry into my sincere desire to work for the company. Next business day an offer / package was socialized with me on the phone followed by a written formal offer that had to be electronically signed. After that there was a waiting period for a background check and approval by the board. Once that was done we collectively identified a start date.
