What if you happen to be stuck in a room with somebody that knows language design extremely well? What if that's because you've proved your worth so far, and were advanced to a valuable employee at a place you want to work.
Do you think you can answer sufficiently to convince a language designer that your position is reasonable?
Perhaps you can, but this is the point about not likely being an expert. Many people express opinions on things which are based in nonsense. By opening yourself up to questioning you risk making a bad impression -- the chance to make a good impression is somewhat thin.
No, an I'm not recommending people lie, or hide their opinions. I hope it did not come across that way. The intent is to stay positive, and steer towards better topics. Even negative opinions can be expressed, but they shouldn't be framed aggressively.
As with Remi, I'm sure you manage well in an interview. Unfortunately, many people I've intereviewed do not. They make silly, easy to avoid mistakes. This experience is where my advice is coming from.
