Applied online, had an initial phone interview with an HR rep (~15 minutes) then a 30 minute call with a manager of the survey team the next day. After that was told I would need to schedule three video interview, one an hour and 45 minutes and the other two would follow based on if they want to continue on with me. The first video interview was awful. My interviewer was late, therefore I was asked the same questions twice. I was thrown into a case study that is supposed to simulate what interacting with a client would be like as a Survey Associate. They provided no guidance, claimed they weren't checking content just what kinds of questions you asked and how you spoke with the "client". Was provided feedback on the spot and it was nerve racking. It would be great if they would explain a bit more on what the overall goal of the interaction is, especially because they aren't entirely explicit about how the relationships are like between associates and clients. Heard back the next day that they are going with someone else. I'm not sure why they have such an extensive interview process. I was asked the same exact things each interview and it didn't seem like there was much discussion between the interviewers about me. Other than that, it's essential you really know GLG's business model well. Watch their videos they have on their site, read through their FAQ section, and be able to describe in your own words why you like their model and why you want to work with them. It isn't a difficult process at all as long as you know that, the problem is it's an intensive process and I feel like I wasted a bunch of unnecessary time, especially because i had to take off from work for that video interview.
