You Got a Finance Interview — Now What? A Complete Preparation Guide

Landing the interview is the hard part everyone focuses on. What happens in the days between getting the invite and walking in the room is just as important, and far more within your control than the recruiting process that got you there. Here's a complete, practical playbook.

The first 24 hours

• Confirm the logistics immediately — date, time, format (in-person, phone, video), and who you're meeting if that information is shared. Reply promptly; slow responses can read poorly even before the interview starts.
• Block real preparation time on your calendar, not just "I'll study when I get a chance." Treat it with the same seriousness as the interview itself.
• If you know who you're meeting, look them up — their background, how long they've been at the firm, any shared connections or overlap with your own experience. This isn't for flattery; it's genuinely useful context for the conversation.

Company and group research: the checklist

• Recent deals the bank or fund has closed, particularly in the specific group you're interviewing with — be ready to reference one or two specifically and intelligently, not just by name.
• The group's specific focus — sector coverage, deal size range, recent trends in that space. See our guide to IB groups if you need a refresher on what different groups actually do.
• The firm's general positioning — how it's regarded relative to peers, any recent notable news (leadership changes, major hires, expansions).
• Your own resume, cold. Every line is fair game for deep follow-up questions. If you can't explain a project or role in real detail, either prepare that detail now or be ready for it to go poorly.

Technical preparation, scaled to the time you actually have

How you prepare should look different with one week versus 24 hours — but the hierarchy of what matters most stays the same.

• One week or more: work through real models yourself, not just review notes — rebuilding a DCF, a comps analysis, or (for PE-focused interviews) an LBO model from a blank sheet is far more valuable than re-reading a prep guide. This is exactly the gap our Investment Banking and Private Equity courses are built to close.
• 2–3 days: prioritize the highest-probability technical questions for the specific seat — walk-through-a-DCF, enterprise value vs. equity value, basic accounting linkages, and (for PE) a basic LBO walkthrough. Drill these until you can answer smoothly, with real understanding behind the words, not a memorized script.
• 24 hours: focus narrowly on the 5–10 most likely questions for this specific interview type, and get genuinely comfortable with those rather than trying to cram broadly. A confident, well-understood answer to a core question beats a shaky answer to an obscure one.

Behavioral preparation: the questions you can actually predict

• "Walk me through your resume." Have a tight, roughly 90-second version ready — chronological, relevant, ending naturally at why you're sitting in this interview.
• "Why this firm / why this group?" Needs to be specific to this firm and group, not a generic answer that could apply anywhere. Reference something real — a deal, a specific aspect of the group's focus, a conversation you had with someone there.
• "Tell me about a time you..." (failed, worked on a team, handled conflict, etc.) Have 2–3 genuine stories ready that you can adapt to different versions of this question, rather than trying to improvise on the spot.
• "What's your weakness?" A real, specific weakness with genuine evidence you're actively working on it reads far better than a disguised strength ("I work too hard").

Logistics people forget until the last minute

• Confirm the dress code if it's not obvious, rather than assuming.
• Bring physical copies of your resume, even for a process that's been entirely digital so far.
• For virtual interviews: test your camera, microphone, and internet connection well before the actual time, not five minutes prior.
• Prepare 2–3 genuine questions to ask your interviewer at the end — generic questions ("what's the culture like") read worse than specific ones grounded in your research ("I noticed the group worked on [specific deal] — how did that come together?").

Day-of mindset

Arrive (or log on) early, not exactly on time. A few minutes of calm beforehand measurably helps most people perform better than rushing in at the last second. If you genuinely don't know the answer to a technical question, say so directly and reason through what you do know out loud, rather than freezing or guessing confidently at something wrong — interviewers generally respect honest, structured reasoning under uncertainty far more than a wrong answer delivered with false confidence.

After the interview

Send a genuine, specific thank-you note within 24 hours — referencing something real from the actual conversation, not a generic template. This is a small thing that a surprising number of candidates skip entirely, and it's an easy, low-cost way to stay memorable during a process where interviewers are evaluating many candidates in a short window.
