Summary

Did two first-round interviews for a Citadel intern role and they were nothing like I expected. No leetcode, just very open-ended design questions rooted in my own past experiences. Felt pretty lost the whole time and ran out of time before I could get to any end-to-end implementation.

Questions Asked (1)

Q1

Open-ended design question based on your own past experiences (no system design, no coding).

Suggested Approach

Choose a past project where you faced ambiguity and had to make design decisions with incomplete information. Structure your answer by first setting the context and constraints, then walking through your design process, trade-offs, and outcomes. Emphasize how you adapted to changes and incorporated product sense to deliver value.

Pro tip: Focus on the 'why' behind your decisions, not just the 'what'. Citadel values engineers who can think critically about trade-offs and align technical choices with business goals.

1. Set the Context

Briefly describe the project, your role, and the initial ambiguity or challenge. Highlight why it was open-ended and what constraints existed.

2. Define the Problem and Goals

Explain how you clarified the problem, identified stakeholders, and defined success metrics. Show how you navigated ambiguity to create a clear direction.

3. Explore Design Options

Discuss the alternative designs you considered, including their pros and cons. Mention how you evaluated them against technical and product criteria.

4. Make Trade-offs and Decide

Describe the trade-offs you made (e.g., performance vs. maintainability, speed vs. flexibility) and justify your final design choice.

5. Reflect on Outcomes and Learnings

Share the results, what you learned, and how you would approach a similar situation differently. Emphasize adaptability and continuous improvement.

Key Points to Mention

  • How you gathered requirements and feedback from stakeholders to reduce ambiguity
  • Specific technical trade-offs (e.g., scalability, latency, cost) and how you balanced them
  • Product sense: aligning design with user needs and business objectives
  • Adaptability: how you pivoted when new information emerged or priorities changed
  • Collaboration and communication with cross-functional teams
  • Measurable impact: metrics or outcomes that demonstrate success
