I applied through a recruiter. I interviewed at AlphaSights
Interview
They sent over materials to prepare for the interview but once I received them I realized that this wasn't really a position I was actually interested in. I did the interview anyway just for practice but I think I could have done a lot better if I prepared more.
They have a asynch video interview first, followed by a personalized synchronous interview. There is also an assessment that follows. There was a language test as well. The difficulty was not too high.
I applied online. I interviewed at AlphaSights (New York, NY) in Apr 2019
Interview
The interview process was an asynchronous video in which they would ask you questions and then you would have one minute to respond. The videos recorded was set in stone, meaning you could not re-record.
