Frequently Asked Questions about Sample Letter for Confirmation of Interview Appointment

Should I always send an interview confirmation letter?

Yes, you should always reply to every interview invitation. Even if the invite says no reply needed, a short polite confirmation shows good professionalism. It only takes 2 minutes and sets you apart from other candidates.

How soon should I send the confirmation letter?

Reply within 2 working hours of receiving the interview invite if possible. If you get the invite after hours, send your response by 10am the next business day. Never wait more than 24 hours to reply.

Can I send this confirmation as a text message?

Only send a text confirmation if the hiring manager first contacted you via text. For all other cases, use formal email. Texts are too casual for most professional hiring processes.

How long should my confirmation letter be?

A good confirmation letter is 3-5 short lines total. Keep it concise, do not add extra information or repeat your full resume. Only include necessary details and polite greetings.

Should I ask questions in the confirmation letter?

You can ask 1-2 simple logistical questions in this letter. Avoid asking about salary, benefits or vacation time at this stage. Save those questions for the actual interview.

Do I need to resend confirmation the day before the interview?

A short polite reminder the day before is appreciated for in-person interviews. Do not resend the full original confirmation. Just a 1 line note confirming you are still coming works well.

What if I need to cancel after confirming?

Notify the hiring manager as soon as possible if you must cancel. Be honest about the reason, apologize politely, and offer to reschedule if you are still interested. Never ghost after confirming an interview.

Can I use a template for this letter?

Yes, templates are fine to use, but always customize small details for each role. Add the hiring manager’s name, the exact role title and interview date. Generic copy will look unprofessional.

Should I attach my resume again to the confirmation?

Only attach your resume again if the hiring manager specifically asks for it. They already have your application on file. Resending unnecessary files will just clutter their inbox.

Every interaction you have with a hiring team counts, even the small ones that feel like formalities. A clear, polite interview confirmation letter is one of the easiest ways to stand out as a thoughtful, reliable candidate before you even answer your first interview question. None of these examples require fancy language or extra effort—they just show you respect the hiring manager’s time.

Pick the template that matches your situation, adjust the details to fit your role, and send it as soon as you get your interview invite. Take 60 seconds to send this note today, and you’ll walk into your interview already starting off on the right foot.
