I applied through university. The process took 6 weeks. I interviewed at EY (Philadelphia, PA) in Oct 2013
Interview
Interviewed first on campus. Interview with Manager and a Senior Associate sat in on the conversation and "hosted" me during the on campus activities (pre-interview reception, waiting for the interview in the career services office). The on campus interview had a lot of behavioral questions, and the interviewer appeared to be filling out a form while I was answering.
Invited to the second round interview in the office. There were upwards of 100 candidates interviewing throughout the day, so it was a sort of unusual environment. Interviewed with one partner, who asked general resume review questions. He was really interested in what specific position I saw myself fitting in at EY.
First round behaviourals and casing, second round plain behavioural with motivation etc. The casing was audit related, with some technicals and then a case about a small firm, and expected difficulties and other regarding auditing.
The interview process was pretty smooth, with the interviews being virtual, and more of a walkthrough of my resume with multiple interviewers. I also found that preparing for follow up questions and pitching myself as a candidate through stories in college was a very helpful approach.
Interview questions [1]
Question 1
What was a challenging moment throughout your time in college?
Very straightforward. Behavioral interviews only. Asked about my on-campus experiences and why I should be a part of the internship program. As long as you practice your behaviorals and have experience to talk about that relates to accounting or even just business in general, you should be well prepared for the interview. It was not very difficult.
