I applied through other source. The process took 1 week. I interviewed at Gensler (Birmingham, England) in Aug 2017
Interview
Very friendly and relaxed, 1h20mins long. Went through my portfolio at my own pace and talked about my work. I had 3 interviewers, all very friendly, asking a lot of questions in a manner that made me feel like they are truly interested. Then had an office tour and interview ended.
