The HM sets up the context first, architecture and goals and all, then drops something like 'this thing is broken, what do you do.' I think the point is less about the answer and more about whether you ask the right questions before diving in.
Start by clarifying the problem and its impact, then walk through a structured debugging process that includes reproducing the issue, forming hypotheses, and isolating the root cause. Emphasize collaboration with the team and consideration of trade-offs in any fix, especially in a banking context where reliability and security are critical.
Pro tip: Demonstrate that you prioritize understanding the system and the problem before jumping to solutions, and always consider the production impact and rollback plan. Mentioning specific tools like logging, monitoring, and debugging techniques shows hands-on experience.
Ask questions to understand the problem's symptoms, scope, and impact. Try to reproduce the issue in a controlled environment to observe it firsthand.
Collect logs, metrics, and traces to identify patterns. Formulate hypotheses about potential root causes based on the data and system knowledge.
Use techniques like binary search, debugging tools, or unit tests to isolate the faulty component. Validate hypotheses by testing changes in a safe environment.
Develop a fix that addresses the root cause, considering trade-offs like performance, security, and maintainability. Verify the fix with tests and monitor in production.
Document the root cause and solution, share learnings with the team, and suggest preventive measures such as improved monitoring or code reviews.

Framed as a hypothetical but it's pretty clearly a signal check on how you handle pressure and ambiguity.
Show that you prioritize understanding the situation before acting, and that you can quickly identify the most critical issues. Emphasize collaboration with the team to gather context and align on immediate next steps, while demonstrating a bias for action to stabilize the crisis.
Pro tip: Mention that you would first check for any ongoing incident response or war room, and ask 'what's the most critical thing we need to fix right now?' to show you can triage effectively.
Spend the first few hours gathering information from team members, documentation, and monitoring tools to understand the crisis's scope and impact.
Determine the most urgent problem that, if solved, would alleviate the most pressure or risk, using input from the team and data.
Quickly sync with your manager and key stakeholders to confirm priorities and get any necessary approvals or resources.
Start working on the critical fix while keeping the team informed, and establish a cadence for updates to maintain transparency.
Once the immediate crisis is stabilized, initiate a post-mortem to identify root causes and prevent recurrence.
