I looked into them a couple years ago... They're the low-cost equivalent of Ryan Air in Asia, no jetways, terminals at the other end of the airport, pay-for-type rating type, etc.

I guess it's good to get experience and leave, but if you have the time why not just get a job with a reputable airline? Try Silk Air, they're the regional (A-320, mind you) airline for Singapore Airleines. Same requirements as Tiger, but better pay and conditions.
