Pearson Test Administrator interview questions

It was short and I was asked specific auestions. I did not feel like the manager was trying to trap me or anything. I also received an answer quickly. I was asked about my past experience and the relevance to the job, also had to tell why I should be hired.

A short phone interview with someone from the HR headquarters somewhere in the midwest, then an in person interview at the testing site, followed by additional interview with someone else. A 3 round interview process for a PART-TIME job. Also they say to wear business casual, but I guess it's the kind where jeans aren't allowed. The interviewer gave me a hard time for wearing jeans, however the worker who greeted me when I entered the room was wearing leggings and a pullover Abercrombie hoody, so I guess they are really inconsistent about enforcing dress-code. The interviewer also implied that they only schedule the bare minimum amount of people they need, which implies that they are: 1. Always understaffed 2. They don't want you to call in sick ever 3. They want you to come in even if the road conditions are too dangerous to drive 4. They want you to basically be on call in case someone else can't make it in. The interviewer mentioned the last point specifically in the interview, which I feel is too much to ask of someone for a PART-TIME job that pays you as little as legally possible. Also, you aren't allowed to use your phone in the waiting room while they make you wait for your interview.
