Hello Mate,
I was asked this exact question in my interview with CTC. Best option for this is to read Flyfish's post a little bit down the page entitled 'My line training diary' - or words to that effect. It's a superb post and it'll give you a very accurate insight of a day in the life of a short haul airline pilot.
Good luck in your interview. Chuck me a PM if you want anymore questions answered reqarding this particular interview.
G.
Ps. Best advice for the interview is to enjoy it! You'd be suprised with how at ease the interviewers will make you feel...
