Business Analyst Intern

1st round consisted of 30 min behavioral and a 30 min case. The interviewer was friendly and conversational. 2nd round came in around 2-3 weeks later and consisted of 3 1 hour long interviewers and a final 15-30 minute behavioral and resume screen. One of the cases was a by a group. All cases are very math and probability based and they let you work on it by yourself and ask any questions as needed. The last case was atypical as it was about conditional probability.
