How a first-round interview is structured

Before you prep a single answer, you should know the shape of the room you are walking into. A first-round interview is not a free-form conversation. It runs in a predictable order, and once you have seen it a few times you can feel the interviewer moving through the checklist.

The order it almost always runs in

Nearly every first round follows the same arc:

1. "Walk me through your resume." The opener. They want a tight two-minute story that gets you from where you started to why you are sitting in this chair. Not a recital of bullet points, a narrative with a direction.
2. "Why investment banking?" Why this job, and why now. They are checking that you know what the work actually is and that your reasons hold up under one follow-up question.
3. "Why our bank?" The specific one. This is where generic answers go to die. Name a group, a deal, a person you spoke with. Show you did not just paste the firm name into a template.
4. A few behavioral and fit questions. Tell me about a time you led something. A time you failed. How you handle pressure. Whether they would want to be stuck in a room with you at 2am.
5. Then the technicals. And there are usually several. Accounting, valuation, a DCF, maybe an accretion or dilution question, maybe a paper LBO. This is the part that most often decides it.

The first four are the warm-up. Real, and you can lose points, but the warm-up. The technicals are the test.

The hard truth at the analyst level

Here is the thing nobody says plainly enough. At the analyst level, the technicals are everything.

You can have a genuinely great first half. A crisp resume walk-through, a thoughtful "why banking," a "why us" that shows you did the work, and fit answers that make you likable. And you can still get a no-go if you bomb the technicals. It happens constantly.

Why interviewers weigh it that way

The main reason is simple. At the analyst level, the technicals basically are the job.

Your day-to-day work as an analyst is building the models and running the analysis that everything else depends on. So when an interviewer asks you to walk through a DCF or move from enterprise value to equity value, they are not testing a proxy for the job. They are testing the job itself. Someone who cannot do the technicals in a calm interview room is not going to do them under real deadlines, and everyone in the room knows it.

There is a second, more human layer on top of that. The person interviewing you in the first round is usually an analyst, associate, or VP, and if they like you they do not hire you, they pass you up the chain to the MDs. That means they are putting their own name on you. Nobody wants to send a candidate forward who then cannot answer a basic technical, so they screen hard before they vouch for you.

Put the two together and it is clear why the technical bar is where it is. Nail the technicals and you are proving you can do the actual work, and you are making it safe for the person across the table to champion you.

The flip side

Now the other direction, because it is not perfectly symmetric.

If you ace the technicals but stumble on the behavioral side, you can still get dinged. Fit is real. If you come across as arrogant, or like someone nobody wants to sit next to at 2am, that is a problem no amount of technical polish fully fixes.

But you still have a chance. A strong technical performance keeps you in the game even when the fit was only okay. The reverse almost never works. Great fit with weak technicals is usually just a polite no.

So prepare the whole arc, but understand what it is really testing. Next, see exactly what the technical half covers, because the universe is smaller than it feels: The range of technicals you get tested on.
