I've seen alot of people say the same thing mate, that they got asked a few questions then got a no.
IMO on the application you need to get them a few things to ask you that are interesting, Im not going to say what myne wer but i'd heard rumours of people who hadnt put anythin good on there apps wer getting the "Are you single" "What do you work as" so I put controversial stuff to talk about and argued with them about it.
just a tip if you go again
