Hello
fighterkok. Correct, I was a DEC way back. In case it gives you any comfort we had to pay costs related to the interview and medical as well, all medical fees, food and accommodation etc. We did get a non upgradeable Economy ticket on SIA to get there and back from the interview, from the nearest airport that SIA had a scheduled service to, not necessarily your home airport. I found them very good to work for but there is no such thing as a free lunch!
