Transferred from DLF to full-time. Process began with an informal meeting with the division lead. A long while later (nothing happens quickly), a req was opened and I was told to apply to it. Another long while later, an interview was scheduled. Interview consisted of several one-on-one meetings with future colleagues plus a technical presentation on a previous project - in my case, my thesis. All of my one-on-ones were people selling me on the company; no hard questions or anything like that. Technical presentation is very important, though. Be prepared for any possible question even tangentially related to your work.

Day-long interview process with about 6-8 different individual meetings and a technical presentation. Met with hiring manager, a couple group members, and several line managers above the group level.
