PwC Senior Software Developer interview questions

The Interview process started with telephonic technical discussion .After clearing that had in a week ago had Second round face to face technical discussion. On same day had Managerial round followed by communion round which is programmed in computer. Then after successful completion of that had hr discussion. For my offer letter after two months

Interview was at PwC SDC, Embassy Golf Links Business Park, permanent position, SSE role. Interview process was good and it took 4 weeks to release the offer letter. PwC Talent Acquisition Specialist was good enough in her job. HR Recruiter there was not at all responding to emails nor available to receive the office phone number. She didn't give her official mobile number and when asked she said she will be responding to the emails which she never did despite of receiving the offer letter. I tried to reach out HR in many ways but in vain. I had so many questions to be clarified after receiving the offer letter but still I continued with Pre Joining formalities and waited for her response till my joining date as I wanted to join PwC despite of having other offers in hand. Finally this irresponsible act by HR Recruiter made me to reject the PcW SDC offer.
