My typical day goes by fast and mostly have me doing super-multi tasking.
Being an end user Tier-2 support, I end up learning new things everyday due to existing and latest technical issues.
Co-workers are always fun to work with because you learn from them everyday, and build a good day-to-day professional relationship.
The hardest part of my job, for me, are the days possessing stagnancy. I love developments.
The most enjoyable part of any job, I must say, is challenges that push you go an extra mile to learn something.
