I applied through university. The process took 2 weeks. I interviewed at Summit Partners (Boston, MA) in Aug 2011
Interview
Cold Called them after reading an old post at my university. They needed an intern, and I had a phone interview with general questions about why i wanted to work there. Then they asked me to come in twice and asked a bunch of personality, and fit questions.
Multiple rounds. First two virtual. Behavioral, Why us, why growth equity. Also asked to explain what you would ask a CEO during a sourcing call. Lots of questions to see if your personality is a good fit for the company and for the role/cold calling.
