I'm not the best developer but I never had any issues during interview except when I didn't want the job. Damn I'm even stammering but still looks like it goes well most of the time. Big note, I'm from the EU, interviewed in France and UK (London), none of them had big technical steps like in the US (from what I read here), nor a billion steps.

Why? I think (I didn't analyze anything) that is because I'm just being myself. I talk to the interviewer like it's a friend. If I think of a joke I just say it. Thoughts like "will be it ok if", "should I say this or that", etc NEVER cross my mind. I'm having a conversation, not a test. Same for technical stuff, if I don't know something I just say I don't know. Hopefully I still have an idea, so I would say something like "I don't know this / never used that, but my first guess would be X", then usually it ends up being a discussion that at the very last would teach me something, even if I don't get the job.

That being said, I understand it's hard to do stuff like that if this is not your default mindset and you are being close to desperate.

I understand what you're suggesting. I do act very confident and unafraid to ask any questions. I don't act "desperate." When I voice my concerns through a forum, I do sound desperate because it's a way for me to voice my emotions; but I never act this way in person.
