The document discusses the two main things to do after a job interview: sending a thank you letter and following up, as well as how to respond to a job offer. A thank you letter should be sent shortly after the interview to build rapport with the interviewer and reinforce key points. It should include the interviewer's contact information, return address, and a signature. When responding to a job offer, one should clarify details, politely accept or decline as needed, and provide a brief explanation if declining.
