Wannebe2013- your Uncle gave you good advice. Basic etiquette and courtesy is never out of place. It probably on its own never got anybody a job (or a nomination)- but I guarantee being seen as ill mannered has cost plenty of folks a second look. Sending a thank you note is a nice touch which indicates that you are familiar with basic professional courtesies. That thought process ought to be followed even prior to your interviews- dress up not down, be overly polite in addressing the interviewer, etc... Does everyone look for this or even make note of it? Obviously not- but the person who is looking for these things will use them as a discriminator if you fail to follow these basics. It would be a shame to hurt yourself because you failed to do something so small- and conversely doing them is both simple and makes you look professional- which of course is the whole impression you are trying to make -right?
