GLG Principal Software Engineer interview questions

Initial phone screening by technology team leader. He asked good questions, and was respectful during the almost hour long call. I was then asked if I had code I had recently written and could share with the engineering team in person. The in-person interview was one of the most interesting and thoughtful I've come across. Members of the engineering team (about 7 of them) and I met in a room for a bit more than an hour, with me projecting my code and talking through important portions of it. The group asked questions and challenged me to explain a few decisions I had made in my code. Following this, the entire team went out to lunch, where I was given the opportunity to ask questions and generally get to know more about the role and the company as a whole. I found the process to be entirely respectful, and even enjoyable, and for any employers reading this who are currently using other methods (including take-home exercises, or whiteboard problem solving) to consider this approach.
