4 months later, they seem to like me and are giving me a fulltime offer.
I initially wanted to go to grad school (MSc) but I am not sure if I should anymore, given the pandemic and what's happening in the world right now.
Should I continue to build my skills at this company or go to grad school.
Would not having a Masters/PhD hinder my career growth somewhere? Should I stay for the money?
I also continued working full-time while pursuing the degree half-time, which alleviated the risk of leaving a stable job. MSc degrees are much less likely to be fully funded than PhDs, and some companies will even reimburse your tuition as well.
It's now possible to do an M.S. while you're working. There are now a number of good online programs, with Georgia Tech's OMSCS at the top of the pile. You might want to take a year or so in your current position and then evaluate whether an M.S. would be a career enhancer. The culture of Master's programs nationally is shifting towards working professionals doing their degrees online, so the case for quitting your job to go back to a full-time residential program is going to get weaker and weaker in the coming years.
Ph.D. is a totally different game and a bigger conversation. Short answer: unless you really, really want to work in academia it's not going to be worth the opportunity cost.

A job like this would provide many connections within academia and would allow you to know something about the Profs and their groups before you sign up.
If you want to pursue further education because you enjoy it, do it, likely it won't be too harmful for your career / savings.
It seems that experience is valued more than degrees, from what I've seen. I would say pursue the job and then worry about a masters.
