Hi guys,

I have a "funny" question about a question I found on the website from more than one source as a typical question in the personal fit part.

That's: "How would you react if you discover there's a mistake on a deck slide you are going to present with your Manager in a few minutes on client site?"

1) How would you guys answer ?

2) What would the interviewer want to assess?

Thanks for the answer!
