Relatively easy, lots of on the spot math, and multiple long rounds of interviews. There is a group case study using Excel that is more number crunching. They ask a lot of 'why' questions. Very communicative and nice interviewers/recruiters.

The interview process consisted of three stages: an initial behavioral interview focused on experience and fit, a take-home assessment evaluating technical and problem-solving skills, and a final review discussing the assessment approach, solutions, and thought process.
