This always stresses me out, not just in interviews (which are actually a bit easier since you try to prepare beforehand there, although I guess the anxiety and stress can cancel this out anyway) but also in everyday chit-chat with other devs. I strongly suspect that I may have ADHD and I'm just unable to randomly talk about things I've been doing even as recently as last week without preparation. I can recall a lot if I actually sit down and calmly trace back some stuff I've been doing years ago, but if I got surprised with a question like "you said in your CV that you used X at job A, what was the thing you liked the most about it?" it could take me the whole interview to just get into the mental state necessary to even recall my experiences with X, let alone put them into proper words. I'll eventually find a perfect answer, but chances are high that it will happen at evening under shower accompanied with a huge regret titled "I should have said that back then" :P
