Robinhood risk for layoffs?

Posting for friend thinking of joining but scared of stock instability - seems they couldn't sustain the big jump from earlier this week and unless things change how can they retain all their high TC (industry relative) employees?
Are/have SWE been at risk of layoff there?

edit - if your vote is based on something factual a comment would also be appreciated :)

edit 2 - forgot, TC: 150k 🙄
