Post Interview Thank You Email 2026: Who Asks You for One

Three instructions, one deadline, and none from MBB

The instruction exists at three firms in our corpus. Everything else about it is left to you.

Three sets of adjectives appear across those rows. Concise and gracious each turn up twice. The words straightforward and to the point belong to EY alone. Nobody publishes a word count or a line count.

Two absences in that table matter more than its contents. McKinsey, BCG and Bain publish no instruction about a post-interview note anywhere in our corpus, so a candidate at any of the three is working without guidance on this point. And KPMG's own United Kingdom page, which is otherwise the most detailed of the three KPMG pages we read, never mentions a note either; it publishes a feedback option for unsuccessful candidates instead.

The one firm that fills the gap indirectly is West Monroe, which tells you who moves first rather than what to write. Its FAQ says the recruiter will contact you once the interview team has debriefed. Read against EY's rule about not calling early, that is enough to answer the timing question at both firms without a template.

One day for the post interview thank you email, and three rules

KPMG Canada publishes the only clock: "Send a personal thank you to your interviewer no later than one day after the interview. Be concise, gracious, and reaffirm your interest in joining the firm."

That is a 24-hour window and three requirements. The same page solves the practical problem that stops most people from meeting it, and it solves it earlier in the day: "Thank the interviewer and ask for a business card or email address." Getting the address belongs to the interview itself, before you are out of the building.

The firm's United States page sets the same expectation without the figure: "Send a thank-you message. It is professional to show your appreciation to your interviewer. Reiterate your interest in the position, and reflect on some of the highlights of the interview. Remember to be prompt, concise, and gracious."

Counting the distinct requirements across the two KPMG pages by hand gives six: concise, gracious, prompt, show appreciation, reaffirm interest, and reflect on a highlight. Concise and gracious appear on both pages, the other four on one each. One deadline, six requirements, and no length guidance at all.

Write it, or call, and when to stop

EY's interview tips page is the only source in the corpus that offers an alternative to writing and the only one that bounds the chase.

On the note: "Send a follow-up note. This further indicates your interest and provides closure to the process. Or make a call, if you have developed relationships with your recruiters. Remember that one thing that you want them to remember about yourself and make sure you communicate that effectively. Don't let too much time pass without making that connection and be sure to use the person's name in your communications."

Four instructions sit in that paragraph: indicate interest, close the process, carry one memorable thing, and name the person. The call is conditional on an existing relationship with recruiting.

On chasing, the firm is blunt: "While creativity is desirable, it's best to remain straightforward and to-the-point in your post-interview communications. And don't call in two days asking about a decision if we said we would be back in touch in, say, two weeks."

That last sentence is the only published rule of its kind we found, and it converts the question of when to follow up into an arithmetic one. The answer is whatever date the firm gave you, and the firms that publish a date are covered in the sibling page on response times.

A promised tip that is not on the page

One observation here is about a page rather than a practice, and any reader can verify it in thirty seconds.

Deloitte's US interview tips page opens with: "Here are six tips to help you make a strong impression from the moment you start preparing to the follow-up after the interview."

The six tips, in the page's own order, are Do your homework, Make an impact, Craft your stories, Use the STAR method, Sell yourself, and Ask questions. None of the six concerns the follow-up. The word thank does not appear anywhere on the page. Its own conclusion describes a narrower scope than its introduction: "From doing your homework to asking questions during your interview, each step is crucial in making a strong impression."

This is worth recording because Deloitte is otherwise one of the most detailed publishers in our corpus, with separate pages on case interviews, scenario interviews and recruiting steps. The absence here is an absence on the page, and it means a candidate interviewing with the firm has no published instruction on this point.

Seven feedback policies, and their thresholds

The more useful question than what to send is what you are owed. Seven sources answer it, and they answer it differently.

Bain publishes the strongest promise in the corpus: "After each interview, you'll learn exactly how it went." No delay, no form, no channel attached to it.

BCG draws the sharpest line: "due to the high volume of applications we receive, we're unfortunately not able to provide individual feedback at the application stage. If you have progressed to the interview stage, you're welcome to reach out to your recruiting contact to request feedback." So the threshold is the interview itself, stated in writing.

Deloitte UK is the only firm that sends something without being asked, and it labels it carefully: "you'll receive a feedback report about your strengths. This isn't the outcome of your assessment, but it will provide you with valuable advice on how to develop your skills."

And SHL, the assessment publisher, gives the instruction the firms do not. It observes that "Many organizations will offer you feedback, regardless of your success", and then, further down the same passage, "If feedback is not offered, ask if it can be made available."

Eleven statuses instead of a chase

The question most follow-up emails are really asking is where the application stands. One firm answers it without any email at all.

BCG's candidate portal publishes eleven statuses: Application Submitted, Application Under Review, Awaiting Additional Information from Candidate, Assessment, Interviews in Progress, Admitted to Program, Program Completed, Offer Extended, Offer Accepted, Offer Declined, and Application Not Selected.

Counting by hand, five of the eleven describe progress and six describe an outcome. A candidate who can read Interviews in Progress on a screen has no reason to send an email asking whether interviews are in progress.

The same FAQ closes one door firmly: "You cannot apply to the same job again if you are not selected or withdrew your application." So a follow-up cannot reopen a decided application at that firm, which is a useful thing to know before writing one.

West Monroe publishes the other half of the answer, which is who moves first: "Your recruiter will reach out to you after your interview with an update on next steps after debriefing with the interview team."

A post interview thank you email template, from published rules

Nothing below is our invention. Templates for this note circulate by the thousand and almost none of them cites a firm. Each line here exists because a firm published a requirement for it, and the firm is named.

1. Name the person. EY asks for it explicitly, and it is the only formatting rule anybody published.
2. Thank them, briefly. KPMG US asks for appreciation. KPMG Canada asks for concision in the same sentence.
3. Reflect one moment from the conversation. KPMG US asks you to reflect on highlights of the interview. One is enough to prove you were listening.
4. Carry one thing you want remembered. EY's instruction is to pick the single thing and communicate it effectively.
5. Reaffirm your interest, and stop. KPMG Canada requires it. EY requires that the whole thing stay straightforward and to the point.

Five lines is the shortest example that satisfies every published rule in the set above. A short thank you email is therefore the compliant one, and anything longer is your own choice rather than a firm's requirement.

Send it inside 24 hours if your invitation came from KPMG Canada, because that firm published the window. Nobody else did.

A note cannot repair a case, which is the honest limit of this page. What decides a case interview is whether the answer came first and the risk was named. Our synthesis rubric weights Answer first 35 out of 100 and Risk 20 for that reason, and the drill runs free and without an account from the tools page. Those weights are ours, read from our own code, and no firm publishes a comparable scheme; the reasoning is on how an answer is assessed.

What no firm publishes about the post interview thank you email

Six gaps, and the first one is the question everybody actually has.

No firm publishes what a thank-you note is worth. Three ask for one. None says it affects a decision, and none says its absence costs anything.

No firm publishes who to send it to after a multi-interview round. Bridgespan's final round has three interviewers and BCG Switzerland's has three. No page in the corpus addresses that case.

No firm publishes a length. Concise appears twice and to the point once, with no reference point.

No firm publishes how long is too long. EY says not to let too much time pass and gives no figure, while KPMG Canada's 24 hours is a deadline for sending rather than a limit on lateness.

No firm publishes a response time for a feedback request. BCG and KPMG UK both publish the right to ask and neither publishes when you hear.

And Bain does not publish how its promise is kept. Feedback after each interview is committed to without a form, a channel or a delay. For the published response times that tell you when a follow-up is even appropriate, see consulting interview response times, for what to ask while you are still in the room see questions to ask your consulting interviewer, and for what to do after a rejection see reapplying to consulting.
