I applied in-person. The process took 1 day. I interviewed at CH2M (Houston, TX) in Feb 2012
Interview
Meaningless, no point as they had made their mind up. Just went through the process and gave them the answers they wanted to hear. At least I now know what they want in people
I applied through an employee referral. The process took 1 week. I interviewed at CH2M in Jan 2016
Interview
I had an internal recommendation and that quickly lead to an in person interview. I talked to an HR person a couple times; once they asked me if I need sponsorship and the other time to schedule the interview. Overall, it was a very positive experience.
