I was interviewed by PitchBook in 2014. The interview process was thorough and relatively straightforward. I was scheduled for 3 separate interviews, and in the final one I took a personality assessment. I was notified at that point that the company would be proceeding with a different candidate.

Very easy and laid-back process, nothing to strenuous, but still formal and professional. Applied via school career website, and received email to set up phone interview. I was abroad at the time, and they were still very accommodating. Second interview was suppose to be Skype, but opted for phone again instead, where MD was looped in. Asked general questions, and after two phone interviews I was hired, competitive process between dozens of applicants.

Pretty simple process. Went through phone screening with recruiter, met with managers for in office, met with directors and then that was really it for me because I didn't get called back after that.
