PwC Associate Consultant interview questions

Some technical questions from department base. Asked maximum questions from favorite subject of engineering. Also asked some mathematical thinking ability questions (not like the calculus etc...) only like the aptitude type.

On campus. There was one aptitude test which was quite hard. The shortlisted candidates were selected from the test and had to go through 3 rounds of interview namely- 1.Techincal round- They asked me about my projects and some core concepts. 2.Partner round- They asked be questions on my resume and some random HR questions. 3.HR round-Typical HR round.
