I submitted my application in October and received an offer in April after 2 assessments and 4 interviews. I believe the process was long due to me still completing my final year of university. The first 2 interviews were general behavioral interviews. I was then referred to the team were I would be hired where I had the final behavioral interview and a final technical interview. All 3 behavioral interviews had the same format and very similar questions. You should prepare 5 or so anecdotes where you showed leadership, creativity, cooperation, ect. The technical interview just asked for more detail about my workflow and thought processes on projects from my resume.

Just got an assessment for behavior, math, logic, and memorization. I received a message soon after saying that my score wasn't sufficient and that I'd have to wait to retake it.
