I applied online. I interviewed at Boston Consulting Group (Toronto, ON) in Dec 2024
Interview
There are 5 questions which are mostly related to technicle questions. Only one question is about self-introduction. They asked past experience and want to know candidate's potential. You have unlimited time to prepare each question, but you need to complete the recording within 2 minutes.
