PwC Tax Associate interview questions

Started with a phone interview with an HR rep who was really nice. We chatted for about 45 minutes and he told me I was his number one candidate and set up an in person for the following week. I met with two a manager and the person I would be replacing for lunch. They took me to a nice restaurant near by and we talked and chatted about the position. Mostly them informing me on what the position consisted of. I then had 4, 30 minute interviews with various managers and a partner. They were all really nice and didn't ask me anything too difficult. I felt it went extremely well. A few days later they told me that it was down to me and one other person and they wanted to have one more phone interview to make a decision. They wanted to know my background a little more and see how it applied to the position and asked me a difficult question I stumbled over a little. I didn't get the job but they liked me and said they will keep in mind. I am currently in the process of interviewing for a different position with them.
