There are 2 levels of interview, with HR and with Technical Managers. Overall, the questions are the not that hard. Researching questions in advance in the web will be a really good preparation to ace the interview.
I applied online. I interviewed at Deloitte (Hong Kong) in Feb 2023

The partner interview is similar to the manager interview but you are free to choose what language you use to answer the questions.

Question 1
Why are you interested in being an auditor? What was your biggest challenge throughout your last work experience /internship? What do you think about the use of technology for accounting firms?
1 interview with the recruiter and then 2 interviews back to back on the same day with two higher-ups. 1 with a senior manager and another one with a partner. Both interviews were virtual.
