My interview for LBS was with an alum, and was conducted over Zoom. There are 3 main components of the interview –
1) Fit questions asked by the interviewer
2) The 10-minute case
3) Questions for the interviewer
I am wary to put a time limit to it, as I have heard wildly different accounts (1.5 – 3 hours). My interview lasted approx. 2 hours and 45 minutes. It was a very informal discussion on topics that ranged from recent US politics, the state of the UK economy, common national roots etc. Expect there to be a structure, but don’t treat it like a job interview.
I would advise to be informed about the world around you and your industry and role. Do also expect to be probed on motivational questions (Why MBA? Why LBS? Why Post-MBA aspirations?) have thoroughly fleshed out answers for these kind of questions.
The 10-min case is a random topic (usually based around current events in the business world) for which you will have 5-min to prepare and 5-min to verbally present. While important, treat it like a brain exercise you are asked to do in some job interviews.
A large part of my interview (45 mins or so) was dedicated to questions that I had about LBS and the interviewer. It goes without saying that find out as much info about your interviewer via LinkedIn as you can. This part of the interview is where you can showcase your interest in the school and highlight the research you have done prior to applying.
