After you have had an informational meeting, an interview, or other substantive interaction with an attorney, it is an excellent idea to send them a handwritten thank you, on personalized stationery, if possible, and sent by U.S. Mail. The gesture will be much appreciated by the recipient, and will get your name in front of them yet again. It may also create a positive impression, which may just be the edge you are looking for during the hiring process.

Her guide, while not specifically about the legal profession, could serve you well in life, in general.
