The interview process consisted of multiple online stages followed by an assesment centre and at the and a 1:1 half an hour interview with a partner in the division i was applying for.
Overall good experience, 2 behavioral interviews. There was a list of prepared questions to ask, but the interview was still casual and conversational. Ample time to ask the interviewer questions.
I applied through college or university. The process took 2 weeks. I interviewed at EY in Oct 2018
Interview
After applying, they reached out for a video-recorded interview. There were basic behavioral questions, but recording yourself w/ a webcam can be very odd. Overall, the video-recorded interview just goes to show you how "personal" EY is.
