I worked there for 6 months ugrading software on the PCs throughout the company. It was pretty easy work most of the time, but took a while because we didn't have the correct (software) tools to perform the job. We were using old OS images that required multiple updates to Windows and/or special software that could have been integrated quickly into the image, but wasn't so we had to spend extra time instaling it on every machine (1 to 100, per department) after it was imaged. Once we moved to the hospitals, nothing was done beforehand so we were going in blind, unlike the other departments that weren't used 24/7, which wasted huge amounts of time (I wasted 6 hours trying to install new machines in an area that wasn't possible to be upgraded at the current time, I only found that out the following day or so). Also information wasn't correlated correctly sometimes, which resulted in wasted time trying to figure out what goes where.
Worked alone a lot, relaxed environment
