It was two 30 minute virtual interviews. They asked mostly about experiences on my resume as well as "Why big 4?" Gave me about ten minutes to ask them questions each. Some of the questions seemed pretty random, for example "How would you get people on campus involved in things off campus?" They also asked how I would handle having to break bad news to someone.

It was an on campus placement interview, they mostly asked about my CV and personal achievements. Some questions were regarding basics of accounting like principles of accounting and treatment of depreciation and other items in all 3 statements.
