Devils Advocate and justinzider are spot on. The secret to flying a jet airliner is power settings and pitch attitudes. Set the correct %N1 (or EPR) and attitude for a given configuration, trim it and hey presto – it’s almost as good as engaging the autopilot!!
A decent airline will take in to account your previous experience. Consequently, if your background is piston or turboprop it would be unreasonable to expect you to cope with non-normal situations and perform QRH drills. Like justinzider said re. SOPs – you’ll be taught these when you get the job.
Don’t become rattled if you are asked to repeat, say, a SID or STAR two or three times. This is by no means an indication of impending failure. Quite the contrary in fact - it is a very typical scenario. In this case the airline is looking for you to recognise any mistakes and, having learnt from them, demonstrate an improved performance next time.
I hope this is of some help and I wish you the very best of luck.
