Pros
If you do a good job for a little over a year you can move into lots of great growth opportunities
ServiceNow was very well configured for the scale it handled. I've since worked at places with SNOW that are much smaller scale environments and be less efficient.
Depending on the desk you are assigned
Cons
It can very much be a slog depending what desk you're assigned.
The shifts can go pretty late and they never pushed doing overnight to anyone that wasn't interested but having a 2-10 shift was rough on my social life and overall rhythm/mental health I was told to hold out until Dec/Jan on a shift change (asked for one in July)
My training was pretty scattered. Sessions were pretty easily disrupted and kinda like a "oh and lets do this next, uh now that."
That said in a support role you're gonna do most your learning with the training wheels off but a lot of on the fly learning for the SNHU project was staunch from how all the VMs, eBooks, courses, etc flowed.
Another situationally dependent note but management was hard to get ahold of sometimes
