A typical day at work : I start my day with more energetic to complete my task as priority.
I learned lot as a Tester and Career part.
Here management will never disturb your work and your self study.
I don't come across any hardest part in my current job but I will make hardest thing simplest may be the reason for that.
The most enjoyable part of the job are discuss and work as a tester and confirm the bug before report.
