Frequently Asked Solutions Architect Interview Questions

Distributed Systems FundamentalsMediumTechnical
59 practiced
You must select a shard key for a customer-facing user profile store expected to scale to 100M users. List criteria you would evaluate for choosing a shard key, and propose one shard key choice with reasons and potential pitfalls.
Architecture and Technical Trade OffsEasyTechnical
37 practiced
Explain cache-aside, write-through, and write-back caching strategies. For each strategy list typical use-cases, the consistency guarantees offered, the invalidation risks, and operational failure modes. Also describe how TTL selection and cache warming affect user experience and cost.
Architecture Decision Documentation and CommunicationMediumTechnical
30 practiced
A team submits an ADR that conflicts with an existing platform ADR (different authentication mechanism). Describe a structured process to resolve conflicting ADRs: impact analysis steps, stakeholder negotiation plan, decision authority (who signs off), documentation updates, and how to preserve an audit trail showing the conflict and final resolution.
Decision Making Under UncertaintyEasyTechnical
51 practiced
You are deciding whether to prototype caching at the CDN edge or implement a full distributed caching layer. Requirements about cache hit rates, object sizes, and origin load are unknown. Describe how you would decide to prototype versus proceed to an operational design, what low-cost experiments you would run, and what success criteria would convince you to move forward.
Database Scalability and High AvailabilityEasyTechnical
37 practiced
Describe leader-follower (primary-secondary) replication topology. What are the responsibilities of the leader versus followers, how is write and read traffic typically handled, and what considerations should be made for leader failover, promotion, and split-brain prevention?
Cloud Platform FundamentalsEasyTechnical
55 practiced
Explain object, block, and file storage types and give one example managed service for each on AWS/Azure/GCP. For each type describe performance characteristics, typical access patterns, and common lifecycle/archival strategies you would recommend to a client storing application logs for 5 years.
Architecture and Technical Trade OffsHardTechnical
35 practiced
A distributed RPC service shows median latency of 20ms but a 99.99th percentile of 500ms, causing user complaints. Diagnose likely causes such as GC pauses, noisy neighbors, retries, head-of-line blocking, or network issues, and propose architecture-level mitigations prioritized by impact and operational complexity.
Architecture Decision Documentation and CommunicationEasyTechnical
34 practiced
Explain what an Architecture Decision Record (ADR) is and why it matters for a solutions architect working on large distributed systems. Describe the typical fields an ADR should include (title, id, status, context, decision, alternatives with pros/cons, consequences, impacted components, security implications, rollout/rollback, author, date, links) and provide a 2-3 sentence example ADR entry that records choosing a circuit-breaker pattern for calls to an external payments API.
Decision Making Under UncertaintyMediumTechnical
39 practiced
Describe clear criteria and examples for when a Solutions Architect should escalate a technical decision to engineering leadership or product management. Include thresholds around cost, schedule, cross-team impact, legal/compliance risk, and sales commitments.
Database Scalability and High AvailabilityHardSystem Design
44 practiced
Design a multi-master replication system across three regions allowing writes in any region that must deterministically resolve conflicting writes and converge. Include conflict-resolution policies (last-write-wins, CRDTs, application-level merge), metadata required (vector clocks), and operational considerations for partitions and eventual convergence.
