I was stood down for an interview and advised of a new date straight away which was 4 weeks hence. Was unable to make the date offered, and suggested a better date for me to attend about 3 days later. That was fine with the recruitment team, did the interview, and am now sitting in HKG with my B777 sitting outside ready to fly back to Dubai via BKK.
Worked for me having shown the commitment of accepting a standby interview with leave and confirmed tickets organised.
