● Market-making practice for trading interviews

Make me a market.
Then do it again.

It's the game trading firms play in interviews. You quote a price, someone who knows the answer trades against you, and you have to work out what they know before it costs you. Two-Way gives you the reps.

01 Interview practice

An interviewer who knows the answer, and wants your money.

They have a number close to the truth and trade against you to make a profit. Every trade is a clue. Follow the flow and you'll find the answer. Ignore it and you'll pay for it.

  • Too wide and they won't play. Close, and they make you tighten until you've committed.
  • Halfway through there's a clue, and on Hard the contract can change under you.
  • A coach tells you what to do next, and a proper debrief tells you what to fix.
Try a round
Interviewer
How many three-digit numbers have no repeated digits? Make me a market.
You
500 at 600, 2 up
Interviewer
I'll buy 2 at 600.
They paid your offer. The answer's probably higher. Move the whole market up.

Interviewer
I don't mind your level, but that's too wide for me. Tighten it up.
Good sign: they like your level. Keep the middle and bring both sides in.
02 Play with friends

A trading floor for your society, set up in one click.

Pick easy, medium, hard or a mix, and the questions and answers are ready, so the host can play too. Everyone gets the order book, the chart and their own position. Nobody can see who's trading with who.

  • Up to ten players by default, or more for a big night.
  • Announcements mid-round move the price, and the quickest to react wins.
  • Put the big screen on a projector and the room watches the market move.

03 How a round works

Simple to learn. Hard to get good at.

01Get a question

Something with a number for an answer, like how many points there are on a Go board.

02Make a market

Quote a bid and an ask. Tight enough to be useful, honest about what you don't know.

03Read the flow

If they keep buying your offer, the answer's higher. Move before it costs you.

04Settle up

The answer's revealed, your position settles at it, and the debrief shows what to fix.

04 What you'll get better at

The things interviewers are actually watching.

01
A sensible first price

Breaking a question down so your opening market isn't a wild guess.

02
Reading the flow

Turning "they keep buying" into "move up", and knowing how far.

03
Managing your position

Skewing your price so you don't end up max long on the wrong answer.

04
Quick mental maths

Position, cash and PnL at any answer, in your head, under pressure.

05
Width and confidence

Tight when you know, wider when you don't, never so wide it's useless.

06
Handling news

Re-pricing in seconds when a clue lands or the contract changes.
