Just one single interview process and it might take a while before they call u up for the contract signing, average difficulty for the interview.usually only a senior manager or Director will interview you
I applied through an employee referral. The process took 3 weeks. I interviewed at PwC (Houston, TX) in Jan 2011
Interview
2 rounds interview. First round only talk to one senior manager. Second round I talked to a senior manager, a partner and a HR manager. Questions are pretty easy. It is more like a communication and see what kind of person you are.
