## Common Questions

<AccordionGroup>
  <Accordion title="Can I switch models during an interview?">
    No, you cannot change models mid-interview. Choose your model before starting the session and test it in the Playground first to ensure it meets your needs.
  </Accordion>

  <Accordion title="Is the most expensive/largest model always the best?">
    Not necessarily. Larger models like Claude 4.6 Sonnet excel at complex reasoning, but for quick coding challenges, lighter models like GPT-5.4-Mini or Gemini 3 Flash might be faster and more practical. It depends on your interview type and personal workflow.
  </Accordion>

  <Accordion title="Should I use different models for different interview rounds?">
    Absolutely! Use coding-focused models for technical rounds, reasoning models for system design, and conversational models for behavioral rounds. Test each scenario in Playground first.
  </Accordion>

  <Accordion title="What if I'm doing a mixed interview (coding + system design)?">
    Start with a versatile premium model like **Claude 4.6 Sonnet** or **GPT-5.4**. These handle both coding and high-level reasoning well. You can switch mid-interview if needed.
  </Accordion>

  <Accordion title="How do I know if a model is working well for me?">
    Ask yourself:

    * Are responses coming at the right speed for my interview pace?
    * Do explanations feel natural and easy to understand?
    * Is the technical accuracy high?
    * Does the tone match what I'd say in my own words?

    If you answer "yes" to most of these, you've found your model.
  </Accordion>

  <Accordion title="Can I use efficient models for real interviews?">
    Yes! Models like **GPT-5.4-Mini** and **Gemini 3 Flash** are fast and capable. They're great for rapid-fire questions or interviews where speed matters more than deep reasoning. Test them first to ensure quality meets your needs.
