LM was my fifth interview during my job search (for reference I am a new PhD). All other companies/universities were very long days (e.g., my Sandia interview was from 8 am to 6 pm) with a technical presentation; this interview was less than 3 hours with no talk. It consisted of a panel interview with the project PI, the program manager, the manager and the staff manager (on conference call). No questions were terribly difficult. While there were plenty of technical questions, the experience seemed to be more of a trying to assess personality and problem solving than raw skills, which is what you would expect and hope for from a division that needs outside of the box thinkers.
