I applied online. The process took 3 days. I interviewed at Hi-Crush (Miami, FL) in Jan 2019
Interview
There are three rounds and if you make it though them all that’s means you’re hired. They were done over around 3 days and they would call you if you past ok to the next round. They would ask you a lot of questions about what you would do in certain situations to see how you would handle things if you worked there.
