I have recently accepted new grad(L3) offer from Google as SWE and my start date is in like 3 weeks. However, I also recently got invited to interview at Scale AI. Should I even take this interview? I am not sure which one will help me more in my career. I want to work at hot startup or even start one myself in the future(also obv resume value in the future in case I want to job hop). How is Scale AI reputation compared to Google's for startup/VC world? What should I even do in this case?
