I've interviewed with one of the "big 4" before, their interview process was very structured and very gruelling. Didn't get the job, feedback was that I wouldn't even meet their junior developer criteria. I'm not bitter about it, just crossed it off as a learning experience and moved on, but every time I see one of these articles about interviewing for tech roles, I'm constantly wondering what the best process is. The big 4 tend to hire the best they can get, and have enough applications to pick from a wide talent pool so can afford to spend time doing whiteboard interviews etc, but for other organisations? I'm not so sure.
