What Do Investment Bankers Do? Day-to-Day Work, Hours, and Levels
Investment bankers advise on deals and raise capital. Juniors spend most of their time on decks, models, and process, not client origination. Here is the honest day-to-day by level.
Students ask what do investment bankers do after seeing pay headlines or LinkedIn titles. The honest answer is less glamorous than marketing videos: you support senior bankers who win and close transactions, often by iterating decks at midnight and keeping workstreams organised.
If you are comparing IBD to lending coverage, do not stop at title prestige. Corporate banking and commercial banking are different jobs with different cash and calendars. This guide stays on classic investment banking execution.
This guide covers day-to-day work by level, how hours really feel, M&A vs capital markets flavour, how banking differs from markets and PE, and a fit checklist before you burn a recruiting cycle. Pair it with how to get an investment banking internship when you are ready to apply.
What investment bankers actually sell
At firm level, investment banking is a fee business: advice and execution on corporate transactions and financings.
| Workstream | What the bank is paid to do | What juniors mostly touch |
|---|---|---|
| M&A advisory | Help buy, sell, or merge companies | Models, buyer lists, CIMs, diligence Q&A, process timelines |
| Equity capital markets | Help companies issue equity | Pitch materials, comps, roadshow support (role varies by desk) |
| Debt capital markets / leveraged finance | Help raise debt | Materials, credit stories, process support |
| Restructuring (where present) | Advise stressed or distressed situations | Models, creditor analysis, process under time pressure |
Clients hire banks for judgement, relationships, and execution capacity. Your Analyst offer is an apprenticeship inside that machine, not a guarantee you will pitch CEOs in month one.
What do investment bankers do as Analysts?
If you join from university, you start as an Analyst. The title sounds senior. The work is junior.
Time allocation (typical, not universal)
Career guides such as Mergers & Inquisitions often summarise Analyst time roughly like this:
| Activity | Share of time (illustrative) | What it looks like |
|---|---|---|
| PowerPoint / pitch books | ~50% | Formatting, story flow, chart updates, comment rounds |
| Admin and random tasks | ~30% | Scheduling, data pulls, binder packs, email chains |
| Excel modelling and valuation | ~20% | Comps, simple 3-statement links, deal math under supervision |
Your group can invert those ratios on a live LBO or a quiet coverage week. The point is not the exact percentages. The point is that beautiful models are not the whole job.
Concrete Analyst deliverables
- Update a comparable companies set and footnote sources
- Rebuild a process timeline slide after the VP changes the auction structure
- Turn a partner's bullet list into a clean strategic rationale page
- Keep a data room tracker so diligence questions do not get lost
- Fix version control when three people edited the same book overnight
If that list sounds tedious, take it seriously. Boredom plus sleep debt, not "hard Excel," is what burns people out in year one.
A realistic week (composite, not a promise)
| Day pattern | What often happens |
|---|---|
| Monday AM | Staffing updates; VP reshuffles priorities after weekend client emails |
| Midweek | Two pitch books in parallel; one live deal workstream needs a comps refresh |
| Thursday night | Senior comments land late; formatting and footnote clean-up run past midnight |
| Friday | "Quiet" only if no Monday pitch; otherwise the book still owns the weekend |
None of this means every week is identical. It means you should interview alumni with questions like "What did you do between Tuesday and Thursday last week?" instead of "Is banking hard?"
What Associates and seniors do differently
| Level | Primary job | How the day feels |
|---|---|---|
| Analyst | Produce accurate work under deadline | Reactive; comment-driven; long nights on books |
| Associate | Quality control, teach Analysts, own workstreams | Still execution-heavy; more client exposure on some teams |
| VP | Manage process and juniors; deeper client contact | More meetings; still owns delivery quality |
| Director / MD | Originate relationships and win mandates | Travel and coverage; compensation tied to fees |
Promotion is not "more of the same Excel." It is a shift from producing pages to owning clients and judgement. Many people love Analyst skills and dislike Associate management. Others reverse that. Decide which problem you want.
Hours, lifestyle, and what "busy" means
Investment banking hours are the lifestyle question behind "what do they do." For the full lifestyle deep-dive (levels, myths, and why the calendar stays sticky), read our investment banking hours guide.
| Signal | Practical meaning |
|---|---|
| Quiet coverage week | Still longer than corporate; pitches and internal asks continue |
| Live sell-side process | Multiple overnight turns; weekends become flexible, not free |
| Pitch season | High volume of speculative books with tight turnarounds |
| Staffing model | Understaffed groups amplify hours even when deal flow is average |
Common junior descriptions land around 70–85+ hours in active periods. Some weeks are lighter. Some are worse. Geography and product group matter: a busy M&A team in New York does not feel like every regional coverage seat.
Travel: Analysts travel less than movies imply. Diligence trips and client meetings increase with seniority and deal type.
Fit test: If you only want the salary and hate deadline theatre, the role usually fails within a year. If you like structured problem-solving under imperfect information, the grind is costly but coherent.
M&A vs capital markets: same firm, different days
"Investment banker" is a family name.
| Flavour | Day-to-day emphasis | Interview flavour |
|---|---|---|
| M&A / advisory | Process, valuation judgement, buyer/seller dynamics | Accounting, comps, deal logic |
| ECM / DCM | Markets windows, investor appetite, documentation | Markets awareness, product basics |
| Leveraged finance | Credit story, structure, sponsor dialogue | Credit metrics, downside cases |
Ask alumni what their last two weeks looked like, not "do you do IB." For markets vs banking as careers, use sales and trading vs investment banking.
Coverage vs product: why your desk changes the answer
Even inside "M&A," a sector coverage Analyst and a product Analyst can live different weeks. Coverage leans on industry narratives, relationship support, and repeat pitches to the same client set. Product seats may see more standardised processes and denser technical work on a narrower transaction type. Neither is "more real banking." Both still demand accuracy under time pressure.
When you network, ask:
- How much of last month was live vs pitch?
- Who comments on your work first: Associate, VP, or MD?
- How often do you touch clients directly at Analyst level?
Those three answers tell you more than a generic "day in the life" video.
What "process work" feels like on a live deal
On a live sell-side, the week is less "learn finance" and more keep the machine moving. You update buyer lists after management meetings. You chase missing diligence answers. You rebuild the timeline slide because the auction structure changed at 9pm. You re-export the same comps set because a footnote source broke.
That cadence is why alumni say the job is attention under fatigue, not only IQ. If you enjoy finishing imperfect work on a deadline more than open-ended research, the Analyst seat can still fit even when the hours look ugly on paper.
How banking differs from PE, HF, and corp fin
| Path | Core job | Why people confuse it with IB |
|---|---|---|
| Investment banking | Advise and execute transactions for fees | Entry brand and technical interviews |
| Private equity | Invest capital, own diligence and portfolio value creation | Bankers exit into PE; pay discussions overlap |
| Hedge funds | Invest with market risk and varying strategies | Another "buy-side" exit |
| Corporate finance / FP&A | Inside one company | Shared Excel vocabulary, different stakes |
Banking teaches transaction craft and pace. PE and HF teach principal decision-making with different hours and politics. Compare exits in hedge fund vs investment banking and private credit vs private equity. For PE pay specifically, see our private equity salary guide.
Mistakes people make when they romanticise the job
| Mistake | Reality check |
|---|---|
| "I will model all day" | Decks and process often dominate junior weeks |
| "I will meet CEOs weekly" | Client time rises with seniority and trust |
| "Hours are always 100" | Intensity clusters around deals and pitches |
| "Any group is the same" | Staffing, culture, and product change the job |
| "Pay alone is enough" | High pay does not fix a personality mismatch |
Should you still apply?
Use this checklist before you fill portals:
- Can you explain what bankers do for clients in sixty seconds without saying "help companies grow"?
- Have you spoken to two people in the product group you want about a real week?
- Are you prepared for comment culture (rewriting the same slide five times)?
- Does the pay band still look rational after tax and city rent?
- Do you have a recruiting plan for deadlines and interviews, not only a fantasy title?
If yes, pick real firms and divisions and treat recruiting as a process, not a title fantasy.
