Terrible Hiring Practices - Transition Project Manager ABM Industries Employee Review

I went through four interviews on my initial search and was told the position got put on hold. One week later the position opened back up so I reapplied and I was told I had the position and would receive an offer letter this past Friday. I had not heard anything so I contacted them today and they said the position was put back on hold after I was informed that I was getting the position. In today's tough times and economy this is a horrible way to treat myself and my family as we were very much looking forward to being a part of this company. They lost a great asset!
