About your past

What they are checking: Whether they understand the difference and have a real reason for wanting judgment-based trading.
Tell me about a competitive pursuit where you lost. What did you change afterward?
What they are checking: How they handle losing, which matters in a job where losing trades happen every day.

What would you do
Make me a two-sided market on the number of windows in this building.
What they are checking: Whether they can estimate under uncertainty and set a sensible width rather than freeze or guess wildly.
You are on a desk and you make a trade that loses money because you misread the screen. What do you do in the next five minutes?
What they are checking: Whether they report mistakes immediately, which is the one thing a desk cannot work without.
The first weeks cover liquid capital markets and our tools before you join a desk. How would you get the most from that period?

About the work
If I offer you a game where you roll a fair die and get paid the number shown, what would you pay to play?

Now you may reroll once after seeing the first roll. What is the game worth to you now?

Pick a market you follow. What has moved it recently and what would change your view?
What they are checking: Whether they truly follow markets and can hold a view while naming what would prove it wrong.
What is the difference between a futures contract and an option, and when would a trader prefer one over the other?
