It was relatively painless, the interviewer who became my boss was pretty easy going and basically just explained my responsibilities, it was almost assumed that I would be given a shot at working there
I went through one interview via the manager in the main office. It was a few questions and overall very easy. I was first approached by another canvasser on the street and pulled in for an interview.
One interview and then a three day period to get 3 new members, team was helpful in supporting you. Some of it is luck of the draw though, I moved to Boston before securing this and it could have very easily not worked out
