I find it draining but rewarding.
I love interacting with people, it fills me with joy making someone else smile or laugh, or helping them feel supported and accepted when times are tough, or lifting them up so they feel clever or helpful or kind. But I also require a lot of solo time to recharge.
I have made several friends in life who I can be in silence with - that really helps me not feel as drained. Being in nature or exerting myself while interacting also makes it less draining (hiking or working out), probably because I can focus more on my own body and experience and less on the social contract and thus be my natural self more.
My colleagues are very understanding of my need to recharge, so we can have a lot of fun together but I can also let them know that I'm socially burnt out and need to work from home or alone with my tunes.
Sometimes burnout takes a long time to recharge, and then i need to force myself with baby steps to get back into socialising, but it is always worth it in the long run.
