I applied through a recruiter. The process took 2 weeks. I interviewed at Tetra Tech (Houston, TX) in Aug 2017
Interview
Listened to the interviewer talk for an hour about her past experiences and other anecdotes about the job. She never really asked me any true interview questions, it felt more like a meet-and-greet to make sure that I wasn't crazy or awkward.

Question 1
After an hour of her talking, the interviewer simply asked me "Do you have any questions?"
