Applied online after talking to someone at an on campus event. First round was a phone interview about two weeks after I applied. Questions were a mix of behavioral and general finance questions. The next step was an on site interview about a few weeks later. This interview was a super day where 25 or so other people were all on site to interview for the internship. They split us into groups of 5 with 4 interviewers per group. We rotated to each of the interviewers for a 30 minute interview with each person and one 30 minute break. The actual interviews all varied. One was just a light behavior one and more of a chat about past work, hobbies and things like that. Another was a fast paced interview where questions were thrown at you about finance, the market, personal questions, and anything else. The other two interviews were a somewhere where in between. What annoyed me about this process was that 3 of the 4 people I interviewed with seemed to be intentionally mean to try and test you. The interviews seemed mostly not be about performing under pressure.
