I applied through a recruiter. The process took 8 weeks. I interviewed at HollyFrontier Corporation (Dallas, TX) in Aug 2016
Interview
Very Long and cumbersome interview process. You will get the impression the company values people, and you may think they are putting in a lot of effort to find the right person, this is not true. The environment has a cult vibe to it. If you are a sheep and would have followed Charles Manson, this is the place for you .
