C1 BA only interview you for cases, they don't care about behavioural part. 1st round of online assessment, with 7 MC, followed by two rounds of case interviews. First round is 45-min mini case, which is pretty straightforward. 2nd round is 2h powerday with 2 cases. Interviewees are pretty nice, but cases are hard.
Interview questions [1]
Question 1
Powerday Cases:
1st case: Amusement Park
2nd case: Breakfast restaurant
Recruiter Call, Mini Case and then a power day with 2 case studies and 1 product case study. Process was overall smooth. Appropriate documents and resources were provided to prep for the interview.
The interview was based on 3 phases. First was screening on call then a video interview with mini case then a power day with 3 phases including product interview, case based and economics based.
First, Screening call: the HR simply walked you thru the interview process and schedule the next round of interview - mini-case. I haven't done the mini case yet. Mini case, just search online for potential cases and prepare for it.
