As an interviewer, if you ask DSA questions, would you be able to solve any questions given by the candidate (3+Yoe) in the same interview?

I will give only those questions I can solve and feel like this can be solvable and these concepts one must know. Asking hard questions doesn't make sense if you really want to hire someone.

I understand your feelings bro. I have also seen the same across many interview panel in my company, those guys don't know shit, but when it comes to interview they think that they are taking bar raiser round for Google/Amazon. This is why I have made a principle of mine, that I will only ask questions which I can solve in the interview.
