Explain Why You Want to Work in Trading
Company: Optiver
Role: Quantitative Trader
Category: Behavioral & Leadership
Difficulty: medium
Interview Round: Technical Screen
The first technical round for a trading role opened with a brief self-introduction and the question of why you want to work in trading. Answer it as you would at the start of a round whose main part is a trading game, so keep the answer short.
```hint Evidence over adjectives
Back every reason with something you have actually done, rather than with words describing yourself.
```
```hint Know the job
Check that your reasons fit what a trader does every day, not only the parts of the job that sound exciting.
```
### Clarifying Questions
- Does the interviewer want your motivation for trading in general, or also for this kind of role and firm?
- How long should the introduction and this answer take, given that most of the round is the game?
### What a Strong Answer Covers
- An accurate picture of the work: pricing under uncertainty, quick decisions, risk taken on those prices, results measured every day
- Two or three specific reasons, each backed by concrete evidence from the candidate's own experience
- A link between those reasons and what the rest of the round tests: probability, quick arithmetic, explaining decisions under questioning
- Brevity and honesty, with no generic praise of markets and no answer that rests on pay alone
### Follow-up Questions
- What do you think separates a good trader from a lucky one?
- Tell me about a decision you made with incomplete information. How did you judge it afterwards?
- Why trading rather than a software engineering or research role?
