Interviewing Options Traders

I’ve been interviewed juniors for an options trading role for the past 2 months and I've noticed a pretty clear pattern. Most can explain Black-Scholes, list the greeks, talk about delta hedging in theory.

But then you ask something basic like what happens to a short strangle when skew steepens aggressively, or what rolling short premium does to margin during a vol spike, and it gets quiet. Yes, I know that in a perfect world you’d look at audited P&L etc. But most juniors don’t have that, and screenshots don’t mean much... can be easily cherry-picked and hard to bverify.

The CFA doesn’t really isolate options mechanics... FRM is just broader risk. I’ve seen a few candidates with the CFOA (options-focused exam) who handled these discussions better, which was interesting, but aside from that I’m not sure there’s a broadly recognized benchmark or tell for options mechanics.

If you were hiring for an options-heavy seat, what would actually make you comfortable that someone understands the mechanics? Mechansics and strategy, not theory.

Based on the most helpful WSO content, here’s how you can assess a candidate’s understanding of options mechanics and strategy beyond just theory:

  1. Scenario-Based Questions:
    Dive into real-world scenarios that test their ability to think critically about options mechanics. For example:

    • "What happens to a short strangle when skew steepens aggressively?"
    • "How would you adjust a delta-neutral portfolio during a vol spike?"
    • "What are the risks of rolling short premium positions in a high gamma environment?"
      These questions force candidates to demonstrate practical knowledge and their ability to connect theory with real-world trading dynamics.
  2. Stress Testing Knowledge:
    Ask about the impact of extreme market events on specific strategies. For instance:

    • "How would you manage a short gamma position during a flash crash?"
    • "What happens to margin requirements when implied volatility doubles overnight?"
      This helps you gauge their understanding of risk management and margin mechanics.
  3. Trade Construction and Adjustment:
    Have them construct a trade based on a specific market view and explain how they would adjust it under different conditions. For example:

    • "If you expect a steepening skew, how would you structure a trade to profit from it?"
    • "How would you hedge a long calendar spread if the underlying starts trending aggressively?"
  4. Practical Exercises:
    Provide a simple options chain and ask them to calculate key metrics or explain the implications of changes in volatility, skew, or time decay. This can include:

    • Calculating the impact of a 10% increase in implied volatility on a straddle.
    • Explaining how a steepening skew affects the pricing of OTM puts versus calls.
  5. Behavioral Insights:
    Ask about their past experiences managing risk or handling unexpected market moves. Even if they don’t have audited P&L, their ability to articulate how they approached challenges can reveal a lot about their practical understanding.

  6. CFOA or Similar Certifications:
    As you mentioned, candidates with the CFOA (or similar options-focused certifications) seem to handle these discussions better. While not a perfect benchmark, it’s worth considering candidates who have pursued specialized education in options trading.

  7. Technical Depth:
    Test their understanding of advanced concepts like:

    • The relationship between gamma and vega in high-volatility environments.
    • The mechanics of exotic options (e.g., barriers, digitals) if relevant to your desk.
    • The impact of changes in interest rates on options pricing.

By focusing on these areas, you can better assess whether a candidate truly understands the mechanics and strategy of options trading, rather than just reciting theoretical concepts.
