Was asked to come in for an interview on three different occasions. The whole hiring process took a little over 2 weeks. First interview was with the HR manager with simple questions and took 5 minutes in total. Second interview was in the conference room with two different managers in NY on Skype. Those same managers I never spoke to again during the duration of my time at GDS. Last interview was with the conference director. Not too professional more of a amicable experience.
