Hot take (& a bit biased) but I think it's extremely valuable to work at FANG or another big co early in your career. 

Lets you establish a great foundation (mature infra & coding practices), lots of smart minds you can learn from, high salaries, etc. 

Learning & growth gets capped so only valuable at the start tho.

I worked at Dropbox as my first job and definitely learned a lot and gained a ton of skills and network I feel glad for 

Then moved to a small company and saw it grow and felt like I could take my learnings there and it made it easier for me to get that job
