PwC Associate Senior Associate interview questions

I applied on their website and received an email from the HR for a connect. I got an interview with a Senior Manager later that week which went well and I progressed further for an interview with a Director. However, just before the scheduled interview, it got rescheduled and an interview with a manager was fixed. It went better than the previous interview, but I received a non-selection email the next day. That was a weird process altogether.
