Hello LC community,

I recently completed FB Data engineering onsite.
Everything went really great.
But when recruiter reached out for feedback, he told me I am going to have a followup ETL round, as they want more signal in coding.
[I actyally tried brute force to get working solution but with hint from interviewer, got to optimal one]
Product sense, SQL and coding wil lbe asked.

Any of DE community have faced followup round?
If yes, how was the experience.

I'll post my full exp, once my followup is over.
