I applied online. I interviewed at AlphaSights (New York, NY)
Interview
Applied online heard back within a month then had a video assessment where I had to respond to 5 prompted questions. A little awkward as you aren't talking to anyone but there is a practice part.
A hirevue completed online followed by a behavioral interview over zoom with an HR rep. It was fairly standard behavioral questions and they ask you to describe what the company does.
Very smooth and takes place quickly after application and with a real person which is nice. The questions aim to test your understanding of the work you will be doing and the competitive landscape of the industry.
Process had three rounds: screener, case study, and final, hour long in-depth interview. The recruiter was very transparent and supportive throughout the process and let you know what to expect with each round.
