I applied online. The process took 2 months. I interviewed at Deloitte (Estambul) in Apr 2013
Interview
I had my first interview with HR Director then had a test for my English and technical knowledge. Then had another interview with an Audit Manager and final interview was with a Partner of Deloitte.
A group case study to solve a problem and we had more than ten minutes to discuss. Then we gave a presentation for our solution. After that, some competency based questions were asked by two managers.
I applied through college or university. I interviewed at Deloitte in Oct 2016
Interview
2 rounds in total excluding info/ntwk session. The second round is more casual in form than 1st one and includes ntwk night, office visit and 3 panels. All 3 interviews started with your own questions, so better make sure you know their work & culture and what you really wanna know
