4 Rounds 1) In person (appprox. 30 min) - 2 Behavioral (standard) and 1 Linked List traversal 2) Hackerrank with 5/6 questions 3) Phone interview (behavioral) 4) Phone interview (technical) - asked to explain concepts such as Python pickling/unpickling. I was told it was going to be behavioral and technical mixed but it was mostly technical.
