bp Project Manager interview questions

First was the phone interview with one of the HR generalist where I was asked about my background, experiences, present salary and sakary expectations. Two weeks later was an email the HR chap informing me of a one-on-one with the hiring manger in three weeks. The interview itself was very casual with the hiring manager and two other technical chaps. Then I received another call four weeks later from the hiring manager informing me I had been selected.
