Met them at my school’s career fair, submitted an application and had a brief (less than an hour) on-campus interview next. Mainly about fit, why Lewin etc. After a while, invited to come in for an in-person interview day at the Falls Church office. Starts with a company overview, then (in some order) have a written case, which is analyzing graphs with a brief prompt, and three interviews each about 40 min. As mentioned, they seem to cover quantitative, qualitative skills as well as why consulting/ fit for consulting. And in the middle, go to lunch with someone in the position that you’re applying for. This seems actually quite relaxed, with the ability to “level” with your lunch buddy. They will of course be very positive about Lewin, but understanding of overall career goals.
