Ensure the email is personalised and references specific detail about the role that you discussed in the interview. If there was a standout moment in the interview, mention it. It is critical that the email doesn’t look like a copy-and-paste.

Keep the emphasis on the positive and state or restate your suitability for the role.

If there is the potential of a second job interview, do not ask directly but state your availability to meet again.

Keep your tone formal. Your grammar and spelling should be perfect. You may have struck up a rapport in the interview; any written communication should be completely professional.

Draft your email, but do not send it straight away. Take a break, do something else, and then come back and give it a final proof-read. One simple spelling mistake could cost you the job.

Send the interview follow up email within 24 hours, or latest, 48 hours. Any later and you could look lazy or disinterested

If you are interviewing with a conservative company, a handwritten interview thank you letter might be appropriate. Choose a professional, high-quality paper stock to write on, and make sure you post it within 24 hours of the interview.
