The question almost every interviewer asks. Pick an answer to see how you do.

  1. Income statement
  2. Cash flow
  3. Balance sheet

Walk me through

Depreciation goes up by £10. Walk it through the three statements.

Step 1 of 3 · Income statement

What happens to net income?

Assumes: Tax rate of 25% (the UK main rate of corporation tax). Tax is paid in cash in the same period. Depreciation is deductible for tax.

Interview practice

Practise out loud. Find out if you'd pass.

Two formats, both marked the way a banker would mark you.

HireVue

Timed, recorded, one-way

Thinking time, then answer on camera, just like the real thing. At the end: would you pass?

Live interviewFollows up

An interviewer that listens

Questions are asked out loud. Then it follows up on what you actually said, like a real first round.

Example

Tell me about a time you got a team back on track.

…so we split the work and finished early.

You said “we”. What did you do?

Every answer gets

  • A mark out of 10From seven criteria, weighted like a banker would
  • What an interviewer would thinkIn plain words, not jargon
  • A model answerSo you can see what a strong answer looks like
  • Three things to fixSpecific to what you said
Example feedback · TechnicalWalk me through a DCF.6.6/10

What an interviewer would think: Right steps in the right order, but you stopped at enterprise value. They'd push you on how you get to a share price.

  • Correctness4/5
  • Technical depth3/5
  • Detail and completeness2/5
  • Structure5/5
  • Clarity and concision4/5
  • Terminology4/5
  • Calibrated confidence4/5

Do this next time

  1. Finish with the bridge: subtract net debt, then divide by diluted shares.
  2. Say why you discount at WACC: the cash flow belongs to all investors.
  3. Name one assumption you'd sensitise, like the terminal growth rate.

The chance of passing is an estimate from your marks against the bar for your level, not a prediction from real interview results.

From application to offer, in three steps

  1. Step 1

    Find your gaps

    A 10-minute diagnostic across every technical topic shows where you stand, and builds a day-by-day study plan around your interview date.

  2. Step 2

    Fix them, a little each day

    Short flashcards and interactive questions that adapt to you. Every answer explains why, and your mistakes come back until you get them right.

  3. Step 3

    Rehearse out loud

    HireVue and live interview practice for technical and behavioural questions, with follow-ups and a mark on every answer.

Your progress page shows how interview-ready you are on every topic, and your study plan tells you what to do each day.

Why it works

Interviews test what you can say, not what you've read.

  • Say it out loudPractise HireVue and live interviews by voice, with follow-up questions and a mark on every answer.
  • Learn from your exact mistakeEvery option explains why it's right or wrong, so the trap you fell into is the one you fix.
  • One right answerAssumptions like the 25% UK tax rate are stated on every question, so nothing is ambiguous.

Questions

Who is this for?

University students applying for spring weeks, summer internships and graduate roles in investment banking, starting with London. You need to be 18 or over.

How do you know the answers are right?

Every question states its assumptions (like the 25% UK tax rate), so there's one right answer, and every option explains why it's right or wrong. The numbers are checked automatically. If you ever spot a mistake, report it from the question and we'll fix it.

Can I talk to a real person?

Yes. Book 1:1 mentoring or a mock interview with someone who has had an internship, offer or experience at firms like Goldman Sachs, Rothschild & Co and Houlihan Lokey. Sessions are 30 or 60 minutes, by video call.

I'm a parent. What would I be paying for?

It starts free: a 10-minute diagnostic, the results and a personalised plan, then 2 days of full access, with no card needed. After that it's £14.99 a month or £29.99 every 3 months, for every topic, all the practice questions and flashcards, and interview practice with feedback on every answer. Plans renew until cancelled, and can be cancelled any time from the account page. UK consumers also have a 14-day right to cancel.

What happens when the 2-day free trial ends?

Nothing is charged: we never ask for a card for the trial. Your study plan, results and progress stay saved and you can still see them. Practising (flashcards, questions and interviews) then needs a plan, from £14.99 a month, which you can cancel any time from your account page.

What happens to recordings and personal data?

Camera video never leaves your device: it's only there so you can watch yourself back. Spoken answers are turned into text, and we don't keep the audio. We don't show ads or sell data, and you can delete your account and everything in it at any time.

Is this affiliated with any bank?

No. We're independent and not endorsed by any bank. Firm information comes from public sources, each labelled with where it came from.

Will it help me cheat a HireVue?

No, and please don't try: banks prohibit outside help during real assessments. This is practice, so you're ready on the day.
