Couple phone interviews first then was flown to Dallas for a 'group' session/interview. Some of it was odd like going to the bar and drinking upon arrival with number of managers and expected to shmooze and what not. Following day we had 3 different tests and 2 presentations/interviews with different managers, bit stressful and highly competitive but worth it
