Very casual, went well. Asked me about mutual friends and why I was interested in finance. No technical questions.

Got involved in their Associate recruiting process via a friend from my time in investment banking (BB) who had been college friends with one of their senior associates. I had a lot of experience in the industry area they specialize in and had already completed 1 year as an associate for another PE fund.

From when I first sent over my resume to them to when I received my first invitation for an interview was just a little under 2.5 months. Received a group email with available interview times with an associate. First call was a pretty standard phone screen discussing my background and getting an overview-view on the fund. Non-technical and purely qualitative / fit questions, although they did have a standardized set of questions every candidate was asked. Very nice guys and relatively easy going, very different from interviewing at larger NYC generalist funds (although there are folks at this fund with that type of demeanor).

Had one additional call with a VP (was the only one to my knowledge who had a second phone screen), discussed my PE background specifically and any deals I'd done and what work I did for my funds portfolio companies. A little more technical, but nothing stressful and mostly qualitative / thought process type questions.

Received invite to superday at office not long after. All day round robbin style meeting w/ majority of investment team with a range of different questions, some very specific / technical accounting questions (think the guy was a CPA if I recall), a lot on thought process towards making PE investments at various stages of a companies life cycle, signs of a good management team, industry trends, etc. There was a type of "case test" but out of respect for the fund, won't say anything about it.

Pretty much everyone I met with were incredibly nice people, seemed genuinely interested in finding out about me and I enjoyed all of my conversations. Given it's one of the top funds in it's space, the process was extremely competitive. Unfortunately, I didn't get an offer, although they said I had been on the final list they made their decision from. Was disappointed, but glad I participated in that process and got to know some of their team members. Great, great fund, probably second to none in the energy space and anyone got that offer is going to have a great experience I'm sure. Also have heard compensation is unbelievable.
