I recently tried 99designs for the first time. They have an unusual model, but every time I was about to get confused, I noticed that their UI cleared up my issue.
I couldn't figure out how they made their site so intuitive.
Then, after I paid for my design, I got an email from them asking me to fill out a Wufoo survey.
That's when I realized how they know their customers well because they keep asking for feedback.
That's why I keep asking for feedback. I could do it off camera, after the interview is over, but I'd much rather be open about my process than hide it.
That's a great point, and I agree that it's always important to get feedback, and that's why I'm glad that you're here on HN discussing the interviews.
One thing to be careful of, however, is making sure you're not disrupting your primary user experience to gather the information.
In your 99designs example, it sounds like they did everything right. They presented a clear, kick-ass UI that guided you through things without being in the way, without cluttering things up with surveys while you tried to do it.
Sometimes I worry that you're in-interview questions are more akin to having 99designs offering a dropdown menu next to each UI element, asking for feedback ;)
