You had the interview, great! Now it's time to follow up. You should always send this to every person you interviewed with as soon as possible (24-48 hours is ideal). This thank you follow up email should be brief, friendly and conversational. It should also remind them of your interest in the job and discuss any relevant details on why you’re qualified.
The follow up email is also a great opportunity to add any significant information you may have forgotten to say in the interview.
Hi [interviewer name],
Thank you so much for taking the time to meet with me on (add day in here). After learning more about the position, I’m very excited about the opportunity to join your team and help [add things YOU would do for them] for [company name]. I feel that my past experience [list the things you did in your past jobs] would be a great fit for your company.
I look forward to speaking with you soon!
Also, if you discussed something personal during the interview that really stuck out to you, you can mention that in the email as well. For example you both love and own Labrador Retrievers and it came up a lot during the interview. Place that information into the email as well, so when they read it they will suddenly put a face to the interview and remember who you were.
Just remember, sending a quick thank you will always help!
