I think behavioral and "tell me a time when" questions can easily be gamed, so I question the effectiveness of asking them. Sometimes I forget specific domain knowledge around a project I worked on 1+ companies ago. But I still have to list it on my resume and thus be able to speak to it...... so I just approximate the details. I imagine you could just full on lie as long as you can detail a technical problem and provide a solution to it.
