Vantaggi
It's a great place to work; the management is supportive if you need to take time off for personal stuff (was especially important during COVID, if a family member got sick).
On the one hand, the software has been around for over 20 years, so the code base is pretty old, but on the other hand, it's being migrated to newer tech, so you get experience with a wide range of technologies, from old to new.
Office perks are nice too: lots of snacks, drinks, espresso machine. And fun company outings like paintball and the Cowtown Cycle Party.
Svantaggi
I wouldn't really call it a con, but as mentioned above, the software has been around for a while, so yeah, if you're a dev, you're gonna have to do some stuff in VB6.
