Investment Banking Superday: What to Expect, How to Prepare, and How to Follow Up
8 min read
- A superday is 4-6 back-to-back interviews testing technical skills, fit, and commercial awareness
- Junior bankers test technicals, mid-level tests resilience, senior bankers test fit and market knowledge
- Consistency across all interviews is critical — interviewers compare notes
- Preparation starts one week before: research deals, interviewers, and rehearse your core answers
What a Superday Actually Is
A superday is the final round of IB recruiting. You will have 4-6 back-to-back interviews, each lasting 30-45 minutes, with different members of the team — from analysts to managing directors. It is physically and mentally exhausting, and that is partly the point.
Every interviewer submits independent feedback. You need to pass all of them, not just most.
What Each Interviewer Tests
| Seniority | Focus | Typical Questions |
|---|---|---|
| Analyst / Associate | Technical depth | Accounting, valuation, modelling — they push until you cannot answer |
| VP | Technical + behavioural mix | "Walk me through a deal," "Tell me about a time you worked under pressure" |
| MD / Partner | Fit and commercial awareness | "Why this firm?", "What is happening in the markets?", "Tell me about yourself" |
One Week Before
- Research 3 recent deals the firm advised on. Know the details: size, sector, rationale.
- Research your interviewers on LinkedIn. Note shared backgrounds and deal involvement.
- Run through your top 10 technical questions until the answers are automatic.
- Prepare your "tell me about yourself" (90 seconds), "why this firm" (specific and genuine), and "walk me through a deal" (if applicable).
- Prepare 3 thoughtful questions for each interviewer.
On the Day
Dress: Dark suit (navy or charcoal), white or light blue shirt, conservative tie. Polished shoes. Minimal accessories.
Arrive: 10-15 minutes early. Not 30 minutes early — that is awkward for the team.
Body language: Firm handshake. Eye contact. Sit upright, lean slightly forward. Do not fidget, tap, or look at the clock.
Energy management: You will have 4+ hours of interviews. Eat a proper breakfast. Bring water. The energy dip usually hits around interview 3-4 — anticipate it.
Five Things That Kill Candidates
1. Inconsistency across interviews. If you tell one interviewer you love M&A and another you are excited about capital markets, they will compare notes and notice.
2. Running out of energy. Your fifth interview needs the same quality as your first. Treat each one as a fresh start.
3. Not having questions. "No questions" signals disinterest. Have 2-3 prepared for each person, tailored to their seniority and background.
4. Badmouthing anyone. Do not criticise previous employers, universities, or other firms. Even subtle negativity is a red flag.
5. Asking about hours or compensation. Never in a first-round or superday. These conversations happen after you have an offer.
After the Superday
Send a brief thank-you email to each interviewer (or the recruiting coordinator) within 2 hours. Reference something specific from the conversation. Keep it to 3-4 sentences — not a paragraph.
Then write down every question you were asked while it is fresh. This is invaluable for future preparation, whether for this firm or another.
