I applied through college or university. I interviewed at AlphaSights
Interview
I was given a list of interview questions to prepare for the interview date. This was through a school recruiting program. The interview was an hour or so long and pretty much was all behavioral and covered all the questions that we were asked to prepare.
Several stages of phone/video interviews. Everyone was very nice and warm, while asking solid questions. They wanted to know a lot about hypothetical problem solving. Last stage was an in-person interview, though I accepted a different offer before this stage.
I applied online. The process took 2 days. I interviewed at AlphaSights in Apr 2019
Interview
Got an email about online interview invitation. Online interview with the process explained well. 5 behavioural questions which change time by time. You cannot do several positions' interviews at once.
