Since when does anyone owe you information about how they make their decisions? If I dump a girl after four dates, I may tell her exactly why ... or I may say "I just didn't feel that spark". It's nicer, and easier, than saying "the more you talked, the more I realized that you've got a grating accent, I don't think much of your family, and your behaviors aren't in line with your stated life goals". Giving a full length run down of my decision making process just opens the door for a conversation that I don't want to have, and isn't going to make anyone happy. Now, if I can reject someone as a candidate for the position of my wife after four dates without a long discussion, then why can't I reject someone for the position of engineer after zero ?
