I was initially contacted by the Manager I'd be working for and interviewed over the phone. I had another phone interview by another person in the department. I then was called in for on-site interviews with the Manager and three other members of the team. The on-site interviews were very thorough and took nearly 6 hours (they did take me out for an hour long lunch). A few days later I received a call from a TI recruiter from their corporate HR department indicating that the manager wanted to extend an offer. I went through a negotiation period with the HR person where we reached agreement, he extended an offer verbally and overnighted a written offer to me.
