Job interview - the follow up
Sending a follow up thank you note can be a useful strategy.
You will want to write more than just "thank you" in the follow up letter. This letter should first paragraph thank the interviewer for their time. You should then restate why you are a good fit for the position and how you will contribute. Finally, close the letter by saying you are eager to move on to the next step. This way, you are reminding the interviewer of who you are, and giving them an opportunity to respond.
Send the thank you letter as soon as possible. You want to stay fresh in the hiring manager’s mind, as they will most likely see dozens more individuals for the position.
A risky strategy is to try and call the employer direct. This is not something we would advise as it has the potential to be bothersome, obstructive and can leave the employer with a negative impression. Remember, just because an employer hasn't made contact on the day they said, doesn't mean they have forgotten about you. If you need a decision as you are considering other opportunities, unfortunately you will need to base you decision on the facts at hand, not on “possible” offers.
If you are going through a recruiter, then channel all communication through the recruitment consultant (or make sure you c.c. them on any correspondence). This is both good practice and respects the fact that the initial relationship is between the recruitment agent and the hiring company.
