lengthy, multiple interviews. Application on line, then a phone call, a sort of mini interview to check qualifications for the job applied for, invite to a group interview, then invite to a personal interview , then another personal interview

I applied online and was called for a phone interview in a few days. Over the following two months, I met with two assistant managers, the store manager and the district manager. I felt all of the interviews went well and was optimistic about being hired (I was, however, concerned that they never called when they said they would to arrange the next meeting. Each time, I would wait several days past the day they promised to contact me, then call them to be told "We were planning to call you today."). They offered me a part time position rather than full time, but were unable to tell me how many hours per week I would be working. Because I am the sole earner for my household, I am unable to accept a job without an assurance of a regular income.
