Hi ci1
I would have to agree with other posters here. Guy obviously knew in advance that he wold be on leave until 18th May, thereby pushing it out to nearly 6 weeks before you'd get a response. Poor show not to respond back to you. My hunch would be that they may have offered the job to someone else and are keeping you on standby in case that doesn't work out. I don't mean to sound harsh, and hopefully I'm wrong, you sound very keen on this job, but I think the time may have come to go back to the drawing board and look at other opportunities on the job front. Good luck anyway
