A couple of times during the last few weeks, I looked at my proposals page to check up on jobs I'd bid for, only to find there was no trace of the job I was looking for. I thought I must have made some mistake that resulted in the proposal not being completed. But then I thought maybe it was because the client hired someone and then removed the job posting. However, I was under the impression that I would receive notification when a job I had applied for was taken down. Anyone have any idea what's happening?
