First interview with a senior then with a partner, mostly fit with some technical questions. Also English test and personality test. Interview year 2017 this may already change now. Nothing difficult just be yourself.
I applied online. The process took 1 week. I interviewed at Deloitte (Singapur) in Nov 2019
Interview
The interview process was pleasant. It was more of a get to know you session with a one to one full-time. It took approximately 15 minutes. The application got back to me in a week's time.
I applied through a recruiter. I interviewed at Deloitte (Nanjing, Jiangsu) in May 2018
Interview
An online test contains several sections and a skype interview with a manager. The hiring manager was nice and asked no difficult questions. The whole application process took about 3 months, but it was worthwhile.
