Most days it's just 2 sectors. Depending on your seniority and preference it could be a 4 sector GCC trip as well. All our 4 sector days are either day flights or 2 day and 2 evening ones. Those are basically 10+hr duty days for 4/5 block hrs. Some people prefer them because they are too junior to get descent day time flights and would otherwise end up with a lot of night flying.
As a new joiner don't expect to see much day light for quite some time. The expansion has stopped untill April 2016. From then onwards it's 1 new aircraft every 5 weeks if I'm not mistaken. We get told very little, if anything, about the companies plans. It changes all the time anyway.
