PwC Audit Associate interview questions

The interview call came via a phone call. They asked me my highest qualification where I clearly stated that I was a semi qualified CA and will soon be appearing for my final exams. On the day of the interview they said the profile was for B.Com grads only. Also when I asked over phone if I would be allowed leave for my upcoming exams the concerned person said I can talk to the HR on the day of the interview and on the interview date the first thing the HR says is that we would be required to work night shifts and no leaves for the initial few months. If that was a job requirement then they should have stated it clearly beforehand. I ended up walking out of the venue after the excel round and wasting 5 days in preparation for the interview.
