I was contacted by a recruiter after having submitted my resume to them for business development and consulting roles.
I was looking to move to Austin, Texas but was still finishing work in London, UK - GLG was excellent with managing international communication and an interview schedule considering great distances and difficulties.
I had two phone interviews, a case study interview, and then four in person interviews (all on the same day) with people in the London office who had worked in the Austin office and could evaluate me on their behalf.
GLG was super efficient and easy to work with in communicating their needs and balancing being friendly and fair in interviews.
