I applied online. The process took 3 months. I interviewed at Strategy& (London, England) in Feb 2020
Interview
There were 2 interviews each with a small part focused on personal interview questions (5-15 min) and then a big part of the time focused on case studies. They were really nice and they give you feedback afterwards.

I applied through university. The process took 3 days. I interviewed at Strategy& (Chicago, IL) in Jan 2015
Interview
There were two interviews and both had standard cases. The interviewers tried to walk me through the cases but it was mainly interviewee led. There was also a second round of interviews a few days later, and after that an offer if you were deemed worthy of one.
