Applied online and was asked to do a screen. Afterwards, was sent an at-home case exercise which I had 45 minutes to complete before reviewing live with the hiring manager as part of the interview. I was then brought in for an onsite interview in which I met 4 employees from different practices. The interviews covered behavioral, cultural, and technical fit. The interviews lasted around 1.5 hours in total. The tone was intense and it seemed like the firm expected everyone to go above and beyond their job duties and have a fundamental calculus understanding.
