Pros
Opportunity to enhance skills in every aspect of the modern datacenter: VDI (VMware, Xen), networking, storage (FC, iSCSI, NFS, CIFS), Enterprise OSes (Windows 2008/2012, RHEL/Debian/Suse, FreeBSD)).
Cons
Limited/unclear professional growth path for 'in the trenches' IT. Frequent layoffs that negatively impact overall perception of the company among current employees. Management calls far too many unnecessary meetings with no clear purpose for all participants.
