The interview process for AlphaSights is quite rigorous. You first submit your resume. If you are chosen for the next round, you have to record a video of yourself answering questions (you don't know what the questions will be prior to recording). If you pass that round, you will be invited to a Skype interview with a live recruiter. If you pass that round, you are invited for an in person interview in the office, where you will meet with at least two people. If you pass that round, you are invited for a final interview with a Director (basically a C list executive).
I first met with Dominique Kleeman (Manager of Client Services), and this was a fairly straightforward interview initially. It was with her that I did a role play scenario where I was given two hypothetical client situations and I had to use a Chromebook to try and find the appropriate professionals on LinkedIn who could consult for our client in this situation. I was given fifteen minutes to search for people, and then I had to present my choices to her and explain why. After presenting my choice for the first scenario, she offered me some feedback before I discussed the second scenario. She told me that the biggest purpose for this role playing exercise is to see how quickly and effectively you can, so keep that in mind.
Up next, I met with Alex Leclair (VP). If you meet with this guy, be prepared to be put through the ringer. He will dissect every possible weakness on your resume, whether you have any gaps or short stints in your work history, or if you took extra time to get your degree. For any question that he asks you, be prepared to be thoroughly explain/defend your answer. Even if your answer is fairly straightforward and well thought out, expect him to react as if you said something very foolish. He is definitely the type of interviewer who wants to test your grit.
