I applied online. The process took 1 week. I interviewed at AlphaSights (Londres, Inglaterra) in Jul 2013
Interview
I applied through the Milkround, and was asked to complete 4 further questions online along with a recorded interview. I found the recorded interview quite awkward - definitely worth practicing beforehand. Overall a good experience, however I get the impression that they are constantly "hiring", making the process quite competitive (not necessarily a bad thing).
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.
I interviewed at AlphaSights (Londres, Inglaterra)
Interview
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.
