Interview process was through Parthenon's on-campus MBA recruiting. I attended their company presentation and info sessions, where I learned a lot about the company and people. Everyone I met was very friendly, interesting, and engaging.
The interview process was two rounds with first round on-campus. It consisted of a case interview and a more conversational interview. Second round was in Parthenon's Boston office, and consisted of a longer, more interactive case, as well as an interview with one of the partners in Boston and one final more conversational interview.
Throughout the process I became more and more excited about the prospect of working at Parthenon. The strategy consulting work sounded exactly like what I was looking for, and the people I met seemed like a great group of colleagues to learn from.
