Key skills to assess
Behavioural Questions
4These questions explore how the candidate has handled real situations in the past. Past behaviour is one of the strongest predictors of future performance.
Describe the most complex cloud architecture you have designed. What were the key constraints and how did you address them?
Assesses depth of architectural experience and constraint-based design thinking
Tell me about a time a cloud migration you led encountered a major unexpected obstacle. How did you handle it?
Reveals resilience, adaptability and leadership during complex projects
Tell me about a time you had to convince leadership to invest in a significant infrastructure change. What was your approach?
Evaluates business communication and ability to build a technical business case
Tell me about a time you had to deprecate or decommission a legacy system as part of a cloud migration. How did you manage the transition?
Reveals change management skills and attention to operational continuity
Situational Questions
4Present hypothetical scenarios to understand how the candidate would approach challenges they are likely to face in the role.
Your monthly cloud bill has increased 40% over the last quarter with no corresponding traffic growth. How do you investigate and address this?
Evaluates cost management skills and systematic troubleshooting
A development team wants to deploy a new service but your security team raises concerns about the proposed architecture. How do you mediate?
Assesses stakeholder management and ability to balance competing requirements
An application experiences intermittent latency spikes during peak hours despite auto-scaling being configured. What do you investigate?
Tests systematic debugging of cloud performance issues
Your organisation wants to adopt a multi-cloud strategy. What factors do you consider and what are the potential pitfalls?
Assesses strategic thinking about multi-cloud complexity and vendor management
Technical Questions
4Assess the candidate's domain expertise, tools proficiency and problem-solving ability with role-specific questions.
How would you design a multi-region, active-active architecture for a financial services application with strict data residency requirements?
Tests knowledge of distributed systems, compliance and data sovereignty
Compare serverless, container-based and VM-based architectures. How do you decide which to use for a given workload?
Tests breadth of compute knowledge and practical trade-off analysis
Explain your approach to infrastructure as code. How do you manage state, versioning and team collaboration?
Tests IaC maturity and practical implementation knowledge
Describe how you would implement a disaster recovery strategy with a 15-minute RPO and 1-hour RTO across two cloud regions.
Assesses DR planning knowledge and practical implementation skills
Competency Questions
3Measure specific skills and competencies against the requirements of the role using structured, evidence-based questions.
How do you evaluate whether to use a managed service or build a self-managed solution on cloud infrastructure?
Evaluates build-vs-buy judgement in a cloud context
How do you approach cloud security differently from traditional on-premises security?
Tests understanding of the shared responsibility model and cloud-native security
What is your approach to documenting and communicating architectural decisions to both technical and non-technical audiences?
Evaluates communication skills and documentation practices
Interview tips for this role
- Ask candidates to whiteboard or diagram an architecture during the interview. This reveals how they think through problems in real time.
- Probe deeply on cost. Many architects can design elegant systems but the best ones also optimise for the bill.
- Look for candidates who ask clarifying questions about business requirements before jumping to technical solutions.
- Assess their ability to explain complex architectural concepts simply. Cloud architects must communicate effectively with diverse stakeholders.
Frequently asked questions
What cloud certifications matter most for a cloud architect?
AWS Solutions Architect Professional, Google Cloud Professional Cloud Architect and Azure Solutions Architect Expert are the most respected. These demonstrate broad platform knowledge. However, certifications should validate experience rather than substitute for it. Prioritise candidates with proven project delivery over those with certifications alone.
Should a cloud architect be hands-on or purely advisory?
The best cloud architects maintain hands-on skills even as they move into more strategic roles. They should be able to write infrastructure as code, debug complex issues and prototype solutions. Purely advisory architects who cannot validate their designs with working implementations often produce impractical architectures.
How do you assess a cloud architect candidate with experience in a different cloud platform than yours?
Core architectural principles transfer across cloud platforms. A strong AWS architect can learn Azure or GCP relatively quickly. Focus on their understanding of distributed systems, networking, security and cost optimisation rather than platform-specific service names. Give them credit for multi-platform awareness.
