How to Write a Thank You Email After an Investment Banking Interview
You just finished your investment banking interview. You nailed the technical questions, your “walk me through your resume” was tight, and you left feeling good. Now what?
One of the most overlooked parts of the IB recruiting process is the thank you email after your interview. Most candidates either don’t send one at all, or they send something generic that does nothing to reinforce their candidacy. Done right, a post-interview thank you email is a meaningful touchpoint that keeps you top of mind and demonstrates the professionalism that banks are looking for in an analyst.
In this guide, I’ll walk you through exactly how to write a thank you email after an investment banking interview — what to include, what to avoid, timing, and real examples you can model.
Does a Thank You Email Actually Matter in Investment Banking?
Let me be straight with you: a thank you email is unlikely to flip a “no” into a “yes.” But it can absolutely reinforce a positive impression and, in borderline cases, tip the scales in your favor. More importantly, not sending one can hurt you — bankers notice when candidates don’t follow up, and it signals a lack of attention to detail or interest in the role.
Investment banking is a relationship-driven business. Every interaction you have with a bank’s team is part of your candidacy. Treat the thank you email as one more opportunity to show that you’re professional, thoughtful, and genuinely interested in the role.
When to Send the Thank You Email
Send your thank you email within 24 hours of your interview — ideally within a few hours if the interview was in the morning or early afternoon. For superdays (full-day interview rounds), send your emails that evening after the interviews are done.
Don’t overthink the timing. The goal is to reach out while the conversation is still fresh, without being so immediate that it looks like you drafted it before the interview even ended.
Who to Send It To
Send a separate thank you email to each person who interviewed you. Not a group email — individual emails, personalized to each interviewer. This requires keeping notes on each conversation so you can reference something specific that came up.
If you interviewed with four people during a superday, that’s four separate emails. Yes, it takes more time. Do it anyway — it signals that you valued each conversation individually.
The Structure of a Strong Thank You Email
A well-crafted thank you email has four components:
1. A Specific Subject Line
Don’t use a generic subject line like “Thank you” or “Following up.” Be specific:
- “Thank you — [Your Name] — [Bank Name] Interview”
- “Great speaking with you today — [Your Name]”
- “Thank you for your time — [Bank Name] [Group Name] Interview”
2. A Genuine Thank You
Open with a sincere thank you for their time. Keep it brief — one or two sentences. Don’t be effusive or over-the-top.
3. A Specific Reference to Your Conversation
This is the most important part. Reference something specific that came up in your interview — a deal they mentioned, a piece of advice they gave you, a topic you discussed in depth. This shows you were genuinely listening and engaged during the conversation.
This is why taking mental notes during your interview matters so much. Even jotting a few words in the elevator right after helps you remember the key moments to reference.
4. A Brief Reaffirmation of Interest
Close with one sentence reaffirming your genuine interest in the role and the bank. Keep it confident but not desperate.
Thank You Email Templates for Investment Banking
Here are two templates you can adapt. Note: you should customize every email — don’t send the same text to multiple interviewers.
Template 1: Standard Post-Interview Thank You
Subject: Thank you — [Your Name] — [Bank] [Group] Interview
Hi [First Name],
Thank you so much for taking the time to speak with me today. I really enjoyed our conversation, particularly your perspective on [specific topic — the XYZ deal you worked on / how the group approaches China M&A / the team’s focus on industrials consolidation].
Our discussion reinforced my excitement about the [Group Name] team at [Bank]. I’m very interested in the opportunity and would love to bring my experience in [relevant experience] to contribute to the group’s work.
Thanks again for your time, and I hope to speak with you further.
Best,
[Your Name]
Template 2: If You Had a Deeper Technical or Substantive Discussion
Subject: Great speaking with you — [Your Name]
Hi [First Name],
Thank you for a great conversation this afternoon. Your insight on [specific topic — the valuation approach for the XYZ deal / how the group thinks about defense contractor revenue recognition / the dynamics of PE-backed industrials M&A] was genuinely illuminating — it’s the kind of nuanced perspective you can only get from someone who’s done the work.
I came away even more excited about the [Group] at [Bank]. The combination of [specific thing that stood out — the group’s deal flow, the team culture you described, the cross-border work] is exactly what I’m looking for in a place to start my career.
Thanks again, and I look forward to hopefully working together.
Best,
[Your Name]
What to Avoid in Your Thank You Email
A few common mistakes that hurt more than they help:
- Generic emails with no personalization. If your email could have been sent to anyone, it will read like it was sent to no one. Personalize every message.
- Correcting a technical answer you got wrong. Some candidates try to use the thank you email to backfill a technical answer they fumbled. Don’t do this — it draws attention to the mistake rather than moving past it. The only exception is if you gave a genuinely wrong factual answer and want to briefly correct it; even then, keep it to one line and frame it gracefully.
- Excessive length. A thank you email should be 4–6 sentences, maximum. This is not the place for a full cover letter.
- Typos or grammatical errors. Proofread every email before you send it. An error in your thank you email after an interview at an investment bank is not a good look.
- Sending too late. An email that arrives three days after your interview signals that it was an afterthought.
- Asking about the timeline. Don’t use the thank you email to ask when you’ll hear back. It’s fine to ask at the end of the interview itself, but the email should focus on gratitude and interest — not logistics.
Special Situations
After a Phone Screen or First-Round Interview
The same principles apply after a phone screen or first-round video interview. These earlier rounds are also opportunities to differentiate yourself. Send a thank you email within a few hours of the call.
After a Superday
Send individual emails to every person you spoke with during your superday — even if it was a 15-minute interview. Superday coordinators and HR contacts also appreciate a brief note. You don’t have to write an elaborate email to every single person, but make sure you acknowledge each conversation.
If You Don’t Have Their Email Address
Most banks provide contact cards or email addresses during the interview process. If not, the standard format is firstname.lastname@[bank].com — you can usually verify through LinkedIn or the bank’s website. If you genuinely can’t find it, a message through LinkedIn is acceptable as a secondary option.
Does the Content of the Interview Affect What You Write?
Yes — the best thank you emails are informed by how the interview actually went. If you had a technical conversation that went well, reference a specific point you discussed. If the interviewer gave you advice about the recruiting process or shared something personal about their career path, acknowledge it. The more specific and genuine the reference, the better.
If the interview was tough and you feel it didn’t go well, still send the email — and keep the tone positive. Don’t reference any struggles. Focus on what you appreciated about the conversation and reaffirm your interest.
Building the Full Picture of Your Candidacy
The thank you email is one piece of a larger puzzle. Networking, resume presentation, technical preparation, and behavioral interview performance are all more important factors. But every detail matters in a competitive recruiting process.
