I also had my interview in April, it was the 2nd day they were interviewing for EF LHR and still haven't got a course date!! I called them and they said that for some reason I was accidentaly skipped over when they were calling people!!!! They're very sorry for the incovenience (understatement??) but there are no courses left and nothing they can do about it!!!!! How good is that???? So people interviewed much later than me are in training and I'm drowning in the holding pool!!!!!
I've now lost any optimism that there ever will be any more courses for LHR within the 12 months that our job offer is valid, so I guess it was all for nothing...
Any optimistic opinions are VERY welcome!!!
