Summary

Behavioral round at Citadel for a software engineer role, focused entirely on conflict and how you handle disagreement with teammates. Pretty standard setup but the follow-ups had some teeth to them.

Questions Asked (4)

Q1

Tell me about a conflict you had with a teammate, such as a disagreement over technical direction, priorities, code quality, or ownership. What was the situation, what did you actually do, and what came out of it?

Suggested Approach

Choose a real, low-stakes conflict where you and a teammate disagreed on a technical decision, and structure your answer to show how you separated the problem from the person. Focus on the actions you took to understand their perspective, the data or reasoning you used to evaluate options, and the concrete outcome that improved the team or product.

Pro tip: At Citadel, they care about intellectual honesty and being 'right' over being agreeable—show that you can disagree without being disagreeable, and that you updated your view when presented with better evidence.

1. Set the context briefly

Describe the project, the teammate's role, and the specific technical disagreement in one or two sentences. Avoid blaming language and keep the focus on the decision, not personalities.

2. Explain your initial position and why

State what you advocated for and the reasoning behind it (e.g., performance, maintainability, delivery timeline). This shows you had a principled stance, not just a preference.

3. Describe how you engaged with the other person

Detail the steps you took to understand their perspective—e.g., scheduled a 1:1, asked clarifying questions, or proposed a small experiment. Highlight active listening and curiosity.

4. Show how you resolved it with data or a compromise

Explain the decision-making process: did you run a benchmark, prototype both options, or escalate to a tech lead? Emphasize objective criteria and willingness to change your mind.

5. Share the outcome and what you learned

State the final decision, its impact (e.g., reduced latency, faster delivery), and how the relationship or team process improved. Reflect on what you'd do differently.

Key Points to Mention

  • Specific technical trade-off (e.g., performance vs. readability, monolith vs. microservice, build vs. buy)
  • Actions taken to understand the teammate's viewpoint (e.g., 1:1 conversation, asking questions)
  • Use of objective data or a small experiment to evaluate options
  • Willingness to compromise or change your mind based on evidence
  • Positive outcome for the project or team (e.g., improved code quality, faster delivery)
  • Improved working relationship or team process as a result

Suggested Approach

Emphasize that you influence through data, reasoning, and collaboration rather than authority. Show that you respect the decision-making process while advocating for your perspective, and that you escalate thoughtfully when necessary. Conclude by highlighting your commitment to the team's success regardless of the outcome.

Pro tip: At Citadel, decisions are often driven by data and rigorous analysis. Frame your conflict resolution around objective evidence and shared goals, and demonstrate that you can disagree and commit gracefully.

1. Listen and Understand

Actively listen to the decision-maker's perspective and the rationale behind their position. Ask clarifying questions to ensure you fully understand their priorities and constraints.

2. Present Data-Driven Arguments

Clearly articulate your concerns using objective data, benchmarks, or prototypes. Focus on the problem, not the person, and tie your points to shared team or company goals.

3. Propose Alternatives and Compromise

Suggest alternative solutions or a middle ground that addresses both parties' concerns. Be open to adjusting your approach based on new information.

4. Escalate if Necessary

If the disagreement persists and the stakes are high, respectfully escalate to a higher authority with a concise summary of both sides. Do so only after attempting to resolve directly.

5. Commit and Support

Once a decision is made, fully support it and help execute, even if you disagreed. Maintain professionalism and focus on the team's success.

Key Points to Mention

  • Influence without authority: using data, logic, and collaboration to persuade.
  • Respect for decision-making hierarchy and the importance of alignment.
  • Focus on shared goals and team success over personal victory.
  • Disagree and commit: supporting final decisions even if you disagreed.
  • Escalation as a last resort, done constructively and transparently.
  • Continuous feedback and learning from disagreements to improve future outcomes.

Q3

What do you do when you genuinely believe the other person is objectively wrong, not just a matter of preference?

Suggested Approach

Emphasize that you separate facts from opinions by seeking objective evidence, then engage the other person respectfully to understand their reasoning. If you still disagree, propose a small experiment or data-driven test to resolve the issue, and commit to the outcome regardless of who is right. Highlight that your goal is the best solution, not winning the argument.

Pro tip: At a firm like Citadel, showing you can disagree and commit is as important as being right—demonstrate that you can advocate your position with data, then fully support the team's decision once made.

1. Clarify the disagreement

Restate the other person's position to ensure you understand it correctly, and ask questions to uncover their assumptions and evidence.

2. Gather objective evidence

Identify what data, tests, or precedents could settle the matter, and propose a quick way to obtain that evidence (e.g., a small experiment, benchmark, or code review).

3. Discuss and debate respectfully

Present your evidence calmly, acknowledge valid points from the other side, and focus on the problem rather than the person.

4. Escalate or decide if needed

If consensus isn't reached, suggest involving a neutral third party or the decision-maker, and be prepared to accept the outcome.

5. Commit and move forward

Once a decision is made, support it fully, even if it differs from your view, and focus on execution and learning.

Key Points to Mention

  • Data-driven decision making: use metrics, tests, or benchmarks to resolve factual disputes.
  • Intellectual humility: acknowledge you could be wrong and be open to changing your mind.
  • Respectful communication: criticize ideas, not people; avoid being condescending.
  • Disagree and commit: once a decision is made, support it wholeheartedly.
  • Focus on the best outcome for the team/company, not on being right.
  • Escalation as a last resort: know when to bring in a tiebreaker to avoid stalemates.

Q4

Looking back at a past conflict, what would you do differently?

Short answer: I said I would've raised the issue earlier instead of letting it simmer.

Suggested Approach

Choose a real conflict where you had a meaningful role, then focus on your own missteps and the concrete lessons you applied afterward. Show self-awareness by explaining what you would do differently and how that change has improved your engineering collaboration since.

Pro tip: Avoid blaming others or picking a trivial conflict; instead, pick a situation where you can show growth in a high-stakes technical environment, and explicitly connect your changed behavior to better outcomes like faster delivery or stronger team trust.

1. Set the context briefly

Describe the conflict in 2-3 sentences: the project, the stakeholders, and the technical disagreement, without assigning blame.

2. Own your contribution

State specifically what you did or failed to do that escalated or prolonged the conflict, showing accountability.

3. Explain what you would do differently

Give 1-2 concrete alternative actions, such as seeking data earlier, using a structured decision framework, or involving a neutral party.

4. Show the lesson applied

Describe how you have since used that lesson in another situation, with a positive result that matters for a software engineer at Citadel.

5. Tie back to the role

Connect the growth to Citadel’s values: rigorous debate, low-ego collaboration, and rapid iteration in a high-performance environment.

Key Points to Mention

  • A specific technical conflict (e.g., architecture choice, code review disagreement, prioritization)
  • Your own mistake or blind spot, not the other person’s fault
  • A concrete alternative action you would take now
  • The lesson you learned about communication or decision-making
  • Evidence that you applied the lesson successfully later
  • Alignment with Citadel’s culture of intellectual honesty and teamwork
