A typical day at work involved phone support, email support, walkup support for NT and Solaris issues. The site was woefully understaffed, and I was closing around 40-50 tickets a day in order to try and keep up.
I learned how to manage time efficiently and live in two different operating systems, and how to function as helpdesk level 1 support and walkup level 2 support at the same time.
Management gave minimal guidance and had minimal engagement with customer service or customer support, and zero long term plan, and as a standard worker my input was not taken into consideration.
The hardest part of the job was lack of manpower. Initially it was me and one other, and I had no training, and we had 2,000 users to support! Eventually a team of four of us got it nailed down.
The most enjoyable part of the job was the lack of manpower. It really forced hard work, creative time management, and careful use of time for troubleshooting and good methodology.
No breaks, expected to work overtime for free.
