I never, ever wear ties. Except I have a job interview tomorrow (semiconductor process engineer) and I suppose I ought to wear one. I have been practicing the knot that my wife knows--apparently "four in hand"--and have been unable to get a symmetrical knot, but I looked it up online and it appears that it is an assymetrical knot by nature. This makes me wonder if I should be using a different knot, or which knots would be most appropriate for a job interview.
