I was reached out via LinkedIn for a role by a recruiter, who was phenomenal! She was super informed on the process and very timely in responding to any questions I had throughout the process.
The first round was split up into 2 parts: 1 case with a LOT of math (could not use a calculator) and 1 brainteaser type question. The recruiter gave me details of what the interview would consist of AFTER I submitted my availability. The interviewer was supportive and communicative throughout, especially when I wanted to check my numbers, since it involved 3-digit by 3-digit multiplication and did some long division as well. This may be specific to the candidates interviewing in the Analytics departments.
Overall, it was a great interviewing experience. Unfortunately the role required me moving to Boston which I was not ready to do at this time, so I stopped interviewing right before final rounds.
