Sample answer is:
I am an early riser. I reach office by 8:30 am. I start my day with writing the list of tasks that I aim to finish on that day. First two hours of the day I spend writing code for the stories that I am working on.
Then I attend my standup meeting and provide status. I discuss my progress with team members. After the meeting, we discuss the design for upcoming story. Then I continue development on my work.
During lunch, I try to join some team member or a senior member to discuss new trends in technology and architecture. At times, I attend lunch and learn sessions to increase my knowledge.
After lunch I spend time on discussing new requirements with product manager. I allocate at least 30 minutes every day for peer code review. In the late after noon I again spend time on code and unit test development to finish my tasks of the day.
At the end of the day, I go through my list again and prepare agenda for next day.Read the full book at www.amazon.com
