Practice the AWS architecture design, Leadership Principle, and service-specific questions used in Amazon and AWS partner interviews.
Practice with AI Interviewer →AWS solutions architect interviews go beyond general architecture knowledge — they test your ability to design systems using specific AWS services, reason through cost and security tradeoffs within the AWS ecosystem, and demonstrate Amazon's Leadership Principles in every answer. Unlike a generic solutions architect interview, the AWS SA loop includes a Bar Raiser round, heavy behavioral probing tied to Leadership Principles, and architecture exercises that expect you to name specific services (not just draw boxes). Whether you're interviewing at Amazon directly or at an AWS partner company, the questions below cover the full scope of what you'll face: AWS-native architecture design, cost optimization, IAM and security, and Leadership Principle behavioral questions. AceMyInterviews lets you practice each round with an AI interviewer that evaluates both your AWS-specific depth and your LP-aligned storytelling — the two dimensions every AWS SA candidate is scored on.
The AWS solutions architect interview loop follows Amazon's structured hiring process. Candidates typically report 4-6 rounds, each designed to evaluate a different dimension. The Leadership Principles thread through every round — not just the behavioral ones.
A 30-45 minute call covering your background, AWS experience, and certifications. Recruiters assess basic fit and often ask which AWS services you've worked with most. Expect questions about your customer-facing experience and comfort with pre-sales scenarios.
A 60-minute session where you walk through AWS architectures you've designed or migrated. Interviewers probe your service selection decisions — why DynamoDB over Aurora, why Lambda over ECS — and test your depth on networking, security, and reliability.
You'll receive a business scenario and design an AWS architecture on a whiteboard or virtual canvas. Interviewers expect you to name specific AWS services, discuss availability zones, regions, and failover strategies.
An interviewer from outside your hiring team who evaluates you against Amazon's hiring bar. This round is heavily behavioral, focused on Leadership Principles like Customer Obsession, Ownership, and Have Backbone; Disagree and Commit. The Bar Raiser has veto power.
One or two rounds of behavioral questions mapped to Amazon's 16 Leadership Principles. Each answer should follow the STAR format with quantified outcomes. Interviewers drill into specifics — vague stories don't pass.
For senior SA roles, you may be asked to prepare and deliver a technical presentation on an architecture you've designed. This tests your ability to communicate to mixed audiences and handle challenging questions.
Leadership Principles are the backbone of every Amazon and AWS interview. As an SA candidate, you'll face 2-3 rounds of LP-focused behavioral questions. Each answer should use the STAR format with specific metrics and outcomes. The principles most commonly tested for solutions architects are Customer Obsession, Ownership, Have Backbone, Dive Deep, Think Big, and Deliver Results.
Architecture design is the core technical evaluation for AWS solutions architects. Unlike generic system design interviews, AWS SA rounds expect you to name specific services, discuss availability zone and region strategies, and reason through AWS-native tradeoffs. Interviewers want to see that you can design production-grade architectures — not theoretical diagrams.
Clarify requirements — ask about users, traffic patterns, latency targets, compliance constraints, and budget before designing
Define scale and availability assumptions — establish expected load, peak traffic, and uptime requirements
Propose specific AWS services — name the services for each component (e.g., 'ALB for load balancing, Aurora for the database') and explain why
Design for multi-AZ and multi-region resilience — show how your architecture handles AZ failures and, if needed, regional failover
Address security and IAM — define IAM roles, security groups, encryption strategy, and network segmentation
Address cost optimization — identify the biggest cost drivers and mention levers like Reserved Instances, auto-scaling policies, or serverless alternatives
Summarize tradeoffs — restate the key decisions you made and what you'd revisit with more time or information
Security is a first-class concern in every AWS SA interview. Interviewers evaluate whether you build security into your architectures from the start — not as a bolt-on layer. IAM design, VPC architecture, and encryption strategies are tested in both dedicated security questions and as follow-ups during architecture rounds.
Cost optimization is one of the five pillars of the Well-Architected Framework, and AWS interviewers test it explicitly. These questions evaluate whether you can design cost-efficient architectures and advise customers on reducing their AWS spend without sacrificing reliability or performance.
AWS SA interviews expect you to name specific services, discuss multi-AZ strategies, and reason through cost tradeoffs in real time. Practice with an AI interviewer that evaluates your AWS-specific depth.
Can you name the right AWS service for each component and explain why you chose it over alternatives? Do you understand service-level tradeoffs?
Can you design production-grade, multi-AZ architectures under time pressure? Do you address availability, security, and cost from the start?
Do your behavioral answers demonstrate Customer Obsession, Ownership, and the other LPs with specific, quantified examples? This is weighted as heavily as technical skill.
Do you naturally incorporate the five pillars (operational excellence, security, reliability, performance efficiency, cost optimization) into your designs?
Can you explain complex AWS architectures to both technical teams and non-technical executives? Can you handle objections and scope solutions realistically?
AWS SA interviews are considered challenging because they test both deep AWS technical knowledge and Amazon's Leadership Principles simultaneously. The architecture rounds expect you to name specific AWS services, and the behavioral rounds require detailed STAR-format stories with quantified outcomes. Thorough preparation across both dimensions is essential.
Coding is rarely a major component of AWS SA interviews. Some roles may include light scripting exercises in Python or CloudFormation/Terraform, but the focus is on architecture design, service selection, and customer-facing communication — not algorithm problems.
The Bar Raiser round is primarily behavioral, focused on Leadership Principles. However, the Bar Raiser may ask follow-up questions that probe your technical depth. Their role is to evaluate whether you meet Amazon's overall hiring bar, with veto power over the decision.
Prioritize core compute (EC2, Lambda, ECS/EKS), storage (S3, EBS, DynamoDB, RDS/Aurora), networking (VPC, ALB/NLB, Route 53, CloudFront), security (IAM, KMS, Security Groups), and integration services (SQS, SNS, Kinesis, API Gateway). Depth on these covers the majority of architecture questions.
Certification isn't required, but AWS Solutions Architect Associate or Professional certification signals baseline knowledge and can help you pass the recruiter screen. However, certifications don't replace hands-on architecture experience — interviewers probe well beyond certification-level questions.
Typically 3-5 weeks from recruiter screen to offer. The loop usually includes 4-6 rounds over one or two interview days: recruiter call, technical deep dive, architecture design, Bar Raiser, and one or two Leadership Principles rounds. Senior roles may add a presentation round.
AWS SA interviews expect you to name specific AWS services in your designs rather than drawing generic architecture diagrams. They also include Amazon's Leadership Principles behavioral rounds and a Bar Raiser — elements you won't find in non-Amazon SA interviews. The overall bar for behavioral storytelling is higher.
Professional-level interviews go deeper on multi-account strategies, complex networking (Transit Gateway, Direct Connect), cost optimization at scale, and enterprise migration patterns. Associate-level questions focus more on core service selection and single-account architectures. Both levels test Leadership Principles equally.
