PwC Experienced Associate Advisory interview questions

Phone screening and two interviews. Interview questions were thoughtful, and I met with staff at all different levels. I got a contingent job offer, but waited a very long time for an actual start date (they were waiting to win work). The recruiter was very responsive to my questions, although I think she should have made more of an effort to check in. The only thing I didn't like was that they offered me an Experienced Associate job, when I applied for a Senior Associate position. They just sent the paperwork and told me to sign it without ever mentioning the change in title and salary. When I asked outright, I didn't really get an explanation.

call with recruiter, then technical screening with a director, and then flew to Houston for a three round interview with Partner, Director and Manager. Offer took about 3 weeks to come in. Recruiter called me to tell me I got the job but didn't give me a formalized offer letter for at least one week after.
