There were two practice tests prior to being invited to interview, including one which was paid. I felt the interview went well, and I felt I had a good chance at getting the position. They asked typical questions - what are your strong suits, what was a time you dealt with a stressful situation at work, etc. At the end of the interview they asked me about pay, and I expressed that I was interested in being paid $20, the dead middle of the $18-22 pay scale they'd advertised. (I'm almost 40 and live in an expensive West Coast city, so I didn't think it was an unreasonable ask.) I will say that after that I sensed a distinct chill in the air. I received an email from them nearly a week days after the time period in which they said they'd get back to me saying that they'd decided to "halt the hiring process for this role."

The interview process was lengthy. There are two tests and two interviews, after which you provide references. The two interviewers were professional, friendly, and responsive. Feedback concerning whether you would be put through to the next round was prompt.
