MediMedia hired me to support their largest office housing 3 divisions. I was the second person in the IT department on the ground floor of a company about to boom. Within 6 months they'd trained me to manage their network access (AD\FTP\VPN), email servers, backup systems, etc, even how to use a fire extinguisher for the emergency response team.
In 6 years MediMedia's umbrella grew from the 3 original companies totaling 250 employees to 19 companies with over 1400 employees. What I learned before the company's restructuring in 2006 will last me a lifetime and am grateful for the experience. Seeing this company grow from the perspective of someone supporting the corporate systems, building relationships with national and international staff, vendors and clients, and being so deeply involved in the growth at that level was an invaluable experience.
The hardest part of the job was also the most rewarding, being trusted to learn new technologies as the need arose. As companies were bought, 'new' systems were introduced and existing systems (email, storage, backups, etc) were expanded to make room for our new MediMedia family members.
