PwC UI Developer interview questions

My interview was schedule to 8:30 am on Saturday and it was a drive; there was more than 200 people for different skill sets. I was told that this was not a drive. I reached to PwC punctually and I left at 12:30, hungry and irritated of much waiting time.

I had one written test first online, after that one Skype interview for 1 hour , after that they called me in their office, I wasted whole day there, back-to-back 4 rounds.........they told that day itself that you are selected and HR will call you, HR called me for a Skype round again after 1 week and had 1 hour discussion. She called me again after one week in office for face-to-face discussion, After 8-9 rounds, wasting my 4-5 days they told that you are selected and we will be sending the offer letter by Monday......after that HR stopped picking my calls , After calling from other no they responded with a package lesser than my current package, When the expected salary was discussed earlier itself, they even took all the documents from me telling that you will get offer on Monday
