Interview questions [1]
Question 1
Why Keystone? Case studies on market entry and calculating damages
Initial HR interview. 1 case interview, 3 super day case interviews, and final Partner interview.
After the initial HR call, it took them a month to schedule the first case interview after a series of cancellations. During the super day interviews, one of the interviewer just didn't show up at all, without any communication. The interviewer who came too was uninterested in me exploring the options for the case.
Overall a very frustrating process. Even though some of the interviewers were good, some were very unprofessional by being late/not attending interviews/interrupting me constantly. I understand they have client commitments to attend to, but at least a communication beforehand would have been good. Overall, was one of the worst interview experiences I have had.
