Not necessarily I start job at 8 o'clock. In fact we start week in monday, at 10 o'clock we take sprint meeting, in the meeting I take new tasks from business team for whole week, we arrange any meeting if we need to discuss anything. During the week if I have anything unclear I discuss with business team. In the friday I make a periodically release. We follow this cycle until we finish all tasks for current milestone.
In another part, is testing team who test my job after I make release.
My hardest part was to go in office in 8 o'clock, because many times I should stay late during the nights, but the most important thing for business team is to finish tasks, which is most enjoyable part for me.
