Some people are humble about their work and abilities. They will never exhibit open pride. Or they don't want to bullshit people and blow smoke up someone's rear. Some may want to switch jobs because they are forced to do poor work and know they shouldn't feel proud about that.
This is probably a 'flaw' I have, but I'm aware of it that I know what I'm expected to sound like when asked this question. Now I'm put in a position where I am being dishonest. You're now testing my ability to BS you to get what I want, and by my nature I am already uncomfortable with BS'ing people.
Now compare this to the person who is too incompetent to not feel pride in the shoddy work they do.
Now the enjoyment part. I can talk about this extensively, but enjoyment is subjective. I could enjoy working on something because of the challenge of the problem, or because I was part of a great team, but it still doesn't speak to my ability to perform the job you have.
Instead of trying to make this into an excuse of being humble, it should be acknowledged as a lack of a certain important trait.
Given that imposter syndrome is well-documented in our industry, it's quite possible that I've done cool things, or impressive things, but not realize that they are cool or impressive because I am in awe of the awesome developers I work with.
Combine that with most of my work being something like "I added new features in our Ember app, and fixed bugs in the UI and backend", and it often is easy to feel like the day-to-day work I do isn't awesome, even if what I am building is (IMO) pretty cool.
The interviewer should not change here, you should change to be able to convey your work and why you think its cool etc. Thats exactly what the interviewer is looking for.
It's amazing to watch you bend over backwards to try and vilify a person who simply strives for accuracy.
