A · Professional problem solving and implementation22
- A template changes only formatting and examples, but output length and tool-call frequency shift. The team wants to skip full regression. How would you tier the risk?
- A new safety policy reduces false refusals but causes sensitive disclosures in a few edge cases. Product wants to keep the satisfaction gain. How would you evaluate?
- A hosted model upgrades without notice. Standard health checks pass, but classification boundaries and output length shift. How would you build safeguards?
- After a safety policy launch, human handoffs double while high-risk errors fall. Operations capacity is limited. How would you assess the result and tune thresholds?
- A model labels some accounts high-risk and automatically denies service, affecting customer rights. How would you set validation, appeals, and human review?
- The business changes “churn” from 60 days without login to 30 days without payment, while historical training and models use the old definition. How would you manage versions and comparisons?
- Given many timestamped records, return the top K by score and preserve earlier items on ties. How would you implement it and analyze edge cases?
- Several sources are individually time-sorted, but total data exceeds memory. Explain how to merge output and handle a source that slows or disconnects temporarily.
- You need retries and timeouts for an async function. On final failure, callers still need each attempt’s error and whether side effects occurred. How would you design the result?
- CPU averages 35%, but the request queue keeps growing and threads wait on external I/O. How would you identify the real capacity bottleneck?
- Database storage grows while cleanup scans cannot reclaim space; reporting transactions run for hours. How would you diagnose and govern this?
- Instance health checks verify only process liveness, while user requests fail on a critical dependency timeout. Adding every dependency to probes may remove all instances. How would you design this?
- Multiple regions accept the same request independently. Idempotency records have a TTL and machine clocks may differ by seconds. How would you prevent duplicate writes at expiry boundaries?
- A live index needs a new shard key as data grows quickly and writes cannot stop. How would you plan old and new indexes and decide when to cut over?
- A multi-tenant query platform shares a database pool. One tenant submits many complex reports and increases latency for others. How would you isolate and meter usage?
- An admin API can change customer states in bulk. A script began calling it directly and caused broad changes. How would you redesign authorization and safeguards?
- A user starts a large export and disconnects; access is revoked while the job runs. The job needs resumability without leaking data after revocation. How would you design it?
- Product data lives in application, CDN, and client caches. After a price update, users see different values. How would you define refresh, versioning, and invalidation semantics?
- A live dashboard uses event-time windows, while finance groups by settlement time and excludes unsettled transactions. A leader believes one report must be wrong. How would you explain and govern this?
- Every read request is logged, driving cost up, while compliance requires evidence for sensitive actions. How would you tier collection and retention?
- Operators, managers, and auditors share a workspace but need different information and permissions. How would you design default views and personalization?
- The product serves professionals and must use industry terms, but new users often stop or choose incorrectly. How would you design comprehension support?

B · Business understanding and domain modeling3
- A payment channel charges a fee on partial refunds, and the contract assigns it to the merchant, but reports combine refund amount and fee. How would you model this?
- A user belongs to several organizations. The browser retains prior-workspace cache, and old organization data briefly appears after switching. How would you design the boundary?
- A missing risk feature is automatically set to zero. Latency and error rates are stable, but denial rates changed significantly. How would you judge whether the default is safe?

C · Value judgment and direction setting3
- A configuration form has 28 fields. A multi-step design may increase abandonment, while one page is hard to understand. How would you gather evidence and decide?
- Search returns hundreds of records, yet users repeatedly combine filters and export to spreadsheets. How would you distinguish retrieval, ranking, task understanding, and result explanation problems?
- A map relies on dragging and zooming, making the same location data hard to access on mobile and by keyboard. How would you design equivalent controls?

D · Delivery and ongoing operations6
- Engineering reports risk weekly, while the monthly business dashboard remains green and leadership commits resources based on it. How would you align reporting semantics?
- Monitoring automatically restarts unhealthy services, but this incident originates in a shared data layer and mass restarts could amplify connection storms. How would you bound automation?
- Several product teams aim to reduce complaints, but categories, channels, and ownership differ. How would you define a shared measure and team actions?
- A shared platform team is preempted weekly by new business requests, delaying reliability and migration commitments. How would you design intake, capacity, and prioritization?
- A third-party service has recovered, but callbacks may have been lost during the outage. Customer-visible state differs from the platform record. How would you confirm impact and communicate?
- The team lists release quality as a quarterly priority, but some focus on rollbacks, others on defects, and others on speed. How would you define a shared outcome?

E · Collaboration, communication, and influence5
- An incident spans an interface contract and caller handling, and both teams believe the other owns it. How would you lead a review and create a shared fix?
- The contract has not changed, but new security reviews materially increase effort while budget is fixed. How would you renegotiate scope, timing, or cost?
- A small user study suggests a workflow obstacle, but the team wants statistical significance before changing anything. How would you move forward?
- Frontline teams report a high risk in the release window, but each upward update is softened to “we are monitoring it,” so decision-makers take no action. How would you correct the information loss across reporting levels?
- An architecture board chooses a new technology, but implementers believe migration risk is underestimated. The decision is announced but work has not started. How would you handle dissent and execution?

G · Learning, adaptation, and sustained growth5
- You learned an effective delivery method at a prior company, but the current team has different technology, compliance, and collaboration rhythms. How would you decide what transfers?
- After joining a remote team, your work is rarely observed and it is hard to tell whether your skills are improving. How would you build feedback loops?
- You have performed well on complex projects, but after one public failure you choose only predictable work. How would you restore judgment and rebuild confidence?
- You changed code-review practices after a retrospective, but team defect rates remain flat. How would you judge effectiveness, sample size, or the mechanism?
- You have mastered current work, but the organization has no new role. You want to grow without neglecting current responsibilities. How would you design the next stage?

H · Professional responsibility and work style5
- You initially helped another team troubleshoot an issue. Months later they assume you own all related work, affecting your core goals. How would you reset boundaries?
- The team defines “resolved” as replying to a customer even if the issue remains, making service metrics look good. How would you correct this?
- A colleague’s change caused a data gap, but they fear blame and have not reported it. The team is deciding whether to expand rollout using incomplete data. How would you respond?
- A teammate temporarily approves requests for an absent lead, but access remains after the leave ends. How would you design expiry and audit for temporary delegation?
- In a joint report, a customer asks to remove data showing their process caused failures or they will not approve publication. How would you handle accuracy, relationship, and contract?
