Had to take two assessments beforehand, met with recruiter, then a case interview with a member of the hiring team. Assessments were long and tedious, the interpretation/visualization one was difficult, math was timed and it's designed for you to not be able to finish. Recruiter was a basic interview/screen. Case (details included below) was rather difficult if you haven't done that type of math in years.

Went through two phone screens and then a case interview over the phone. The case interview went very well, and the interviewer immediately told me he wanted me to come in and interview onsite. I received an email from HR to schedule an onsite, replied with my times, and then never heard back, even after following up. Very poorly handled.
