Thanks you, that a great advice. I think you are right about applying pressure on youself, that might be the case. I'm getting very anxious trying to get things right from the first shot.

Another thing I noticed is that the less you care about the outcome of the interview, the more likely you are to succeed.

That said, it seems that the key to master those interviews seems to be the mind control, rather than raw experience and intelligence.

On your last point: I don't have any problems showing off expertise and I have a bunch of cool side-projects. The problem is that I'm weak at the low-pass filter of a basic technical screening.
