Spotless Meter Reader interview questions

The initial phone screening was good, the interviewer was very pleasant and set a time. He was a bit pushy about trying to make it the next day but I made it clear that wasn't possible but could do 2 days later. I had to fill out pages of paperwork in handwriting that could have been sent to me via email more easily. The questions were quite bizarre for a position as simple as a meter reader that only pays $22 an hour. Asking what motivates you to apply for a position like that is either going to attract dishonest answers or brutally honest ones. I said the job would complement my evening classes for my masters degree. I gave this completed paperwork to the interviewer who was different to who screened me via the phone. He briefly glanced over the paperwork and kept asking me why a Masters student would want a job like this and said I obviously would leave as soon as I got offered a better job. Safe to say I knew I wasn't going to get the job after that and the interview was a waste of time.
