Applying in Style

At the Phone Screen

If they don't give it to you, ask for your interviewer's contact information, "in case you have any questions".

Then email them a short thank-you note on the same evening.

At the Technical Interview

Here, too, ask for your interviewer's contact information if they don't give it first.

"It was great to meet you. Do you have a card in case I have any more questions?"

Again, email each of your interviewers a short thank-you note on the same evening. Make it different for each one by commenting on something you talked about at the interview.

"I appreciate what you said about the emphasis on testing at [company name]. I value the flexibility that comes with testing and would love to work with like-minded engineers to learn and share best practices."

It's ok to be cheesy. Cheesy people are easier to work with than cynics.
