I was originally supposed to have a BCG first round interview in November but recently requested the possibility of rescheduling it due to an unexpected scheduling conflict. HR got back to me very quickly, saying they have first rounds at the beginning of every month and they could reschedule my interview to December.
This made me wonder - what is the ususal statistic for how many people get invited to a first round and then move on to the second round? Are the number of openings to give out offers predetermined or based on the quality of the applicants?
Thanks!
