I applied through my university and received an invite to the first round interview. It was supposed to last a full hour of simply behavioral questions. 15 minutes into the interview the recruiter told me he was moving me on to the final round to take place that Friday. Two days later I received a call from HR saying I did not receive a final round interview. I followed up with the recruiter who interviewed me, and he said that after HR re-reviewed my resume they decided my major/background was not a fit even though he thought I fit with the company.

there is a Phone screen and then first round case interview, afterwards second round group case lastly slide submission for a case interview. Fairly straightforward, there were differences from interviewee to interviewee
