It was a pre-recorded video interview. Asked basic behavioral questions, as well as why you were interested in the company. There were 5 questions, and I was given 1 minute to answer each of them.

Interview
Interview process took 2 months. After submission of application, I got an invitation to join online interview. It was a bit awkward as I had to basically talk to the camera w/o interaction. After the online interview, I got invited to join the 1st on-site interview. It was mostly behavioral. The interviewer was very attentive and friendly so you probably don't have to worry too much. However, be prepared for the 2nd on-site interview as it would test your case solving skills.
I applied online. The process took 2 weeks. I interviewed at AlphaSights (Chicago, IL) in Oct 2019
Interview
The first round was a one directional video interview. You had 30 seconds to answer the questions on the screen that they gave to you. After recording your answer it was sent in and you were not able to change what you said.
