Ferguson interview questions

This was a pretty disappointing experience. Not because there was no job offer but because it was a waste of everyone's time involved. I had two phone interviews with recruiters and then met with 3 people at a facility for the final interview. It was 2 weeks between each step… except it took less than 24 hours to receive the "Dear John" email. What was disappointing was how excited I was about the opportunity and had no problem doing the manual labor work in the warehouse for a few months to get a "ground-up" view of the company. But when I met in person with the managers, everyone talked down the job! They basically told me how much it sucked and how many people had been in the position. They revealed they had trouble keeping trainees and most left within three months… many within 1 month! I walked out of the interview not even wanting the job anymore. I would've worked really hard.. but why would I want to work for people who have no faith in me from the start?
