1st round was a quick phone interview. No more than 30 minutes. All behavioral questions. What is an example of a time you did this? What is an example of a time you failed at what you were doing and how did you respond? (These are not the actual questions, but just examples). At the end of the call the recruiter said she would like to have me have an in office interview the next weekend. The night prior to the office interview, the partner in my service line hosted all the interns interviewing for a position in my office. It was informal, and I quite enjoyed it, however, they are judging you here based on how social and friendly you are, so keep that in mind. In the in office interview in the morning, many of my interviewers I had met the night before. It is good to keep your interactions from the prior night in mind because the majority of the questions asked in office are conversational based on your resume, and if you can tie this back to your prior knowledge of the interviewer, all the better. I had two partner interviews both following this resume review format, and the case study was not hard either. Just know what a SWOT analysis is. Thanks to Glassdoor I was capable of knocking this part out of the park. Honestly, the hardest part of the interview process was the phone interview. EY's mentality is they can make someone a good accountant or consultant, but they can't make a person to match their corporate identity. So in the grand scheme of things this is what they are looking for in their interviews, do you match the company mentality?
