Neutral experience

Difficult interview

Application

I applied online. The process took 2 weeks. I interviewed at Charleston Water Systems (Charleston, SC) in May 2025

Interview

Interview process was two rounds. One on the phone and one IRL. First interview included most of the same people as were in the 2nd. Was very chill. 2nd was pretty formal and, I felt, difficult.
