Process starts with 2 technical assessments, followed by 4 interviews with the first one being a case study interview. The case study interview was conducted by a junior analyst with very little experience in both work and interviews. The interviewer only parroted case study questions, did nothing to have a conversation about the direction. Case interviewers normally nudge the interviewees in specific directions if there is a specific answer they're getting at, but he did not do so.
Technical assessments have very strict time limits, requires candidates solve math problems in incredibly quick succession. It also seems like they get anyone that's available to do the case interview, this part of the process will be a dice roll on whether you get someone who knows what they're talking about or how to interview.
The case study interview is followed by standard interviews on fit. The priorities in the technical assessments don't make any sense.
