Ways to impress a potential employer....?

[J]

The simplest way to differentiate yourself from the herd is to keep your name and credentials in front of them.

send an email, reminding them of your qualifications and desire to work there. find one thing from the news or their site or advertising that they are doing and mention it prominently and wish them the best with whatever project.

Send a note (by post) saying thank you, but reminding them of your good points and your willingness to do 'what needs done'.

follow up with a phone call, be pleasant, ask if there is anything else they need from you to help choose you
