I had a friend who went through one for a local refinery. It was 6 weeks between each interview, of which there were three levels, and you didn't know if you were on the list for the next interview for nearly all of those 6 weeks had passed. If you need a job, and you are competent, the economy is fairly decent, you would have found 3 before that. But Corporate wanted to be thorough...It's for the provincial government, and on their little info videos they straight up say that the interview process takes a long time. I didn't realize they meant THIS long.
