Yes, I can tell, because in the interview situation I'm sitting next to them.

And print statements are sometimes the superior choice.

This ties into my other comment that these things can be heavily subjective. As long as it gets the job done, I prefer print statements used by somebody who uses them as a sharp knife to gain understanding of what's going on over somebody just clicking buttons in a fancy UI but has no clue. (And vice versa, obviously.)

I'm talking about universities not interviews.

Print debugging is sometimes useful but sometimes indicate the person doesn't know about tracepoints/logpoints.
