the entire process from when i applied to when an offer was made spanned over a 8 week period. i had two over the phone interviews with the hiring manager/director over a 2 week period. then i didn't hear anything for a couple weeks. i then received a call to interview with the team. during this interview, i had a panel type q&a and had to give a presentation. after that interview it took the hiring manager about three weeks to get back with me. my advice would be to research behavioral types of questions and have very defined/concrete answers.
