I applied online. The process took 2 weeks. I interviewed at FTS International (Fort Worth, TX) in Feb 2018
Interview
It was quick to start an then turned into a casual conversation about other than work things. It did not appear that the interviewers knew much about the engineering position that I was applying for and they certainly were not able to answer any of my questions about the job.
Interview questions [1]
Question 1
How do you feel about being away from home for 3 weeks out of each month?
