Facebook Fullstack vs backend role interview differences specially the design round

Yes, I’ve been told this too. Did you find anything since you’ve last posted?

For future people searching this topic: I did the fullstack interview at FB and it was 3 or 4 DS/algo questions and 1 API design (instead of system design) question.

Any diff in the phone technical?

I wonder why backend suggest 5yoe and full stack 3yoe
