Like I said in my first reply in response to your original post, you can expect to be worked like a dog for the first 6 months of being with the company - this is because you are 'cheap labour' during this time.
Rosters are constructed in a 6 on 3 off pattern, this means that you work for 6 days (usually 3 early duties followed by 3 late duties) and then you have 3 days off. The good thing about this roster system is that you can always work out easily when your days off up months if not years ahead of todays date!
Your 6 days on would consist of either 2 sector or 4 sector days (you get a mixture in every working week), along with home and airport standby's and contactable duties. Some people say that the 6 and 3 roster system is fatiguing but I personally love it!
Any more questions, feel free to ask
