Here's my experience.
Last year I went for their interview. I'd just failed BA mainland, and wanted some practice. Its was very similar to BA mainland.
They called me and ask if I'd like to attend. At the time I had around 1500 hrs 737NG time.
Think there were around 8 guys on my day, and believe there were 4 days of recruiting. The rumour was 8 positions where being sought after, 2 DEC and the rest FO's. I know for a fact that at least 4 of the 6 FO positions filled where done so with guys from FTE, could have been all 6, but I know personally of 4. The rest I can't comment. Good on them for recruiting cadets, and not asking them to pay for a rating I say, but the salary kind of reflects that, and not many people flying even for the company I do, would leave for that salary.
Good luck
