Why is that? Do they even choose someone to do the job? Eventually, the job is closed, so I guess they must have found someone - assuming the job post is legitimate. But whom?
Do you quote on such jobs? Do you ever get such a job? Or do you even get a reply to your quote?
And how come the number of bids/quotes may be registered and made visible, if one is expected to quote outside of proz/other sites?
Yes, I have sometimes quoted on such jobs by email, and been awarded the job. I have also sometimes quoted on such jobs by email, and never received a reply. I have found it is very rare to receive a negative reply -- either no reply, or success.
