What a Day in Investment Banking Actually Looks Like

There's a running joke among first-year analysts: "The hours aren't that bad — it's the uncertainty that kills you." And honestly, that's the most accurate description of investment banking life I've heard.

I'm not going to sugarcoat this. The hours are real. But the internet has turned IB into this mythological grind where people work 120 hours a week and sleep under their desks. The reality is more nuanced.

The Morning (9:00 - 10:00 AM)

Most analysts roll in around 9 or 9:30. Not 6 AM. Not 7 AM. The whole "be first in the office" thing is more of a consulting culture move. Banking teams tend to start between 9 and 10, and the real work accelerates as the day goes on.

Your first move is checking emails. If you're on a live deal, there might be 30-40 emails waiting from Asian or European counterparts who were working while you slept. You'll triage those, flag what needs immediate attention, and start a running to-do list that will change six times before lunch.

Late Morning (10:00 AM - 12:00 PM)

This is when the actual modeling and analysis happens. If you're lucky enough to get uninterrupted time here, you'll build out whatever your VP or Associate asked for yesterday. Maybe it's a comps table. Maybe you're updating an LBO model because the client changed their revenue assumptions for the third time this week.

The work itself is... honestly kind of repetitive once you know what you're doing. The first three months, everything feels impossibly complex. By month six, you realize 80% of the job is formatting PowerPoint slides and updating Excel models with slightly different numbers.

Afternoon (12:00 - 6:00 PM)

Lunch happens when it happens. Some days you eat at your desk at 11:30 because a pitch is due at 2. Other days the whole team goes out for a proper meal. It depends entirely on deal flow.

The afternoon is meeting-heavy. Client calls, internal reviews, deal team syncs. You'll sit in on these calls mostly to take notes and action items as a junior person. Occasionally someone will ask you a question directly and your heart rate will triple.

Around 3 or 4 PM, the "comments" start rolling in. This is when senior bankers review whatever you sent them that morning and come back with changes. Entire pages of a pitchbook might get rewritten. You'll want to scream. You won't. You'll just open the file and start revising.

Evening (6:00 - 10:00 PM)

Here's where banking diverges from a normal job. At 6 PM in most careers, you'd be heading home. In banking, 6 PM is when you start your second wind of focused work. The senior people have finished their meetings, they've sent their feedback, and now you execute.

Most weeknight dinners are $30 of Seamless eaten at your desk. The bank pays for it, which is both a perk and a signal that they expect you to be there.

Late Night (10:00 PM - ???)

On a slow week, you might leave at 10 or 11. On a live deal, you might be there until 1 or 2 AM. The worst nights are when a client call is scheduled for 8 AM the next day and the deck isn't done. Those are the 3 AM nights.

But here's the thing people don't mention: there are also slow weeks. Stretches where you leave at 7 PM multiple days in a row. They just don't last very long, and you never know when they'll end.

The Weekend Question

Yes, you'll work weekends. But not every weekend, and not always the full weekend. A typical month might look like: one weekend fully off, two weekends with a few hours on Sunday afternoon, and one weekend that's basically a workday. It varies wildly by group and by how many live deals you're on.

Why People Stay

The money is obvious — first-year total comp around $190K-$220K is hard to ignore at 22 years old. But the people who actually enjoy banking (and they exist) talk about something else: the acceleration. You learn more about how businesses work in two years of IB than most people learn in a decade. Every deal is a crash course in a new industry, a new set of financial dynamics, a new set of stakeholders with competing interests.

Why People Leave

The ones who burn out usually aren't bothered by any single hard week. It's the accumulation. It's missing your friend's wedding because a deal went live. It's canceling vacation plans twice. It's the Sunday night dread that never fully goes away, even on slow weeks.

Two years as an analyst is the standard tenure. Most people move to private equity, hedge funds, corporate development, or business school. Some stay and make Associate. Very few regret doing it, but very few want to do it forever.
