There was only one interview, and it was fairly simple. The interviewer asked questions about whether or not I work well with others, if I could handle working in the cold, why I wanted to work there etc. He then explained the requirements of the job and the salary.

They ask questions like "do like working alone or with people?" "how many times can a person miss work or be late?" and "describe a situation you had a conflict with a co-worker and how you handled it." I later found out that for every position they interview 10 people and pick the most personable one.
