Personally I agree with the other reply that advises against asking this.
Everything in a job interview should be to frame you in a positive light.
I see way too many candidates try and play the humble route, and all it does is sell them short. There’s a fine line between too humble and too full of yourself , and neither side is good to find yourself on. This particular question seems to me to be too humble.
Questions like this may seem like it makes the candidate seem humble and open to feedback, but in actuality whenever someone has asked something like this it has made them appear insecure and planted more seeds of doubt in the interviewers mind since they now have to think about their shortcomings.
Maybe phrasing it a better way would help:
“What qualities are you looking for, for this role?”
“Are there things you think i should brush up on , assuming I get this role?”
“Where do you see me best being able to contribute in this role?”
Those questions give you the same data points, leaving you to infer where you may be lacking. It leaves the interviewer with a sense of your confidence without seeming too full of yourself, and generally the wording makes them consider you as if you’re in the role, versus not in it.
Again, a job interview is a sales pitch. People should be honest while balancing keeping the tone positive.
You wouldn’t sell a car by pointing out its flaws. Don’t sell yourself the same way.
