Following up on an interview is one of the most important steps to creating a relationship with the prospective employer.
For one, it reminds the interviewer of who you are. Chances are, you are not the only person that they are interviewing. When you follow-up with the interviewer, it gives the person 10 seconds to remember your conversation and anything that may have stood out.
What to expect
Please don't expect a response to your follow-up email. A response is no indicator of how well you did in the interview.
The interview or recruiter should generally follow-up with you within 2-3 weeks if you are continuing in your interview process (Please understand that this is a guideline. Some companies will tell you the same day, next day, or even months later).
If you receive a response to your follow up email, do not expect it to include more details regarding the interview process.
Generally, recruiters and interviews conclude the interview with communication expectations. You should still send a thank you email.
The Nitty Gritty
Odds are your interviewer is busy enough with his or her day job that setting aside 30 minutes to interview you took a lot of coordinating. This in no way undermines your time, just understand that it takes a lot to schedule an interview. Sending a quick thank you lets the interviewer know three things: 1) you understand what was previously mentioned 2) you thought your conversation was meaningful and would like to continue 3) you are still interested in the position after the interview.
What should you say?
1. Something quick - like 5 sentences quick.
2. Something meaningful. Remind the interviewer of one of the most important skills/qualities/experiences you conveyed during the interview.
3. Something personal. Disclaimer *be professional at all times* The balance is in the hope that you made a connection with the interviewer. Remind them of that connection.
Make an impression
Remember in middle school when we stopped passing notes and started texting instead? The same thing happened with follow-up emails. It's very rare that an interviewer will receive a hand-written thank you note. If you aren't very confident that you nailed the interview, send a written thank-you card to seal the deal.
Send it quickly. Generally 24-48 hours is the rule of thumb to follow. I suggest having a template drafted in your email before the interview. That way when you are leaving, you can add in personal flare while it is still fresh in your mind.
Write One Yourself - Samples
The message you send may depend on how your interview takes place! Below, you emails I wrote, one after an in-person interview, the other after a virtual interview. Luckily, my interviewer sent me a confirmation email the night before our virtual interview, which I alluded to in the follow-up email.
