I have been telling myself this, but it's small comfort. :) I am aware that interviews generally have about a 1/5 success rate overall. Since I've done "only" 6 onsites, that means that I should have an expected 74% chance of a job offer so far. I would be truly worried if I had failed 10 or 11 onsites in a row. As of now, I'm just... concerned. :/
