They went dark for a while but did a hireview and then one virtual interview before hearing that I received the position.
Virtual interview was with my direct managers once actually accepted
One hire view and 2 more rounds after that. Fairly straight forward but they want to see how you can add value and ideas. Know the landscape of the company.
Four interviews followed by a written assignment. The assignment was not disclosed up front - it was a 72 hour period to do about two hours of work. They ghosted me after the assignment.
