PwC Sr. Associate interview questions

I applied through LinkedIn and the manager get back to me after a month. I just go through 1 stage of interview within 30 minutes. The process is really easy I could say. Follow up after a week and got the offer after 3 working days

I went in through referral. The entire process comprised three stages & lasted around 50 days. 1st stage: Screening call. Pretty generic conversation around salary expectations, planned holidays, current notice period, preferred start date and so on. 2nd stage: Round One interview. A senior manager and a manager on the panel. CV walk through. Competency based question. Lasted and hour. Very chilled out atmosphere. Fairly comprehensive. 3rd stage: Round two interview. A director/partner and a senior manager in the panel. One is expected to do a presentation on a case study. Case study is emailed an hour ago. Presentation is 15 min long and is followed by other situation based questions. Fun round.
