Interview questions [1]
Question 1
How many years would it take until the investment in advisors turns profitable?
Straightforward, well structured & well explained. Long duration, with 5 30-ish minute interviews total spread out over the course of a couple of weeks. Great support, information on requirements/evaluations readily available.
Too long - too many rounds. Had to play a game first, then multiple rounds. No follow ups after I was rejected - I got ghosted.
Did not enjoy it - obviously this was a long while back and I was too young to notice but not a good behaviour. Truly no respect.
The process made me feel very unprepared but I was able to get through with all of my studying. I would recommend anyone about to interview with them look at Harvard Business cases as reference
