How to Hire a Cloud Solutions Architect (AWS)

Q: In AWS, if you want your application to adapt to sudden increases in user traffic, which service should you primarily configure to automatically add or remove EC2 instances based on demand?

Correct answer: Auto Scaling Group. Auto Scaling Groups automatically adjust the number of EC2 instances based on real-time demand, ensuring your application scales efficiently.

Q: In a high-traffic production environment, which AWS approach is most effective for ensuring scalability during sudden load spikes?

Correct answer: Configure EC2 Auto Scaling groups paired with an Elastic Load Balancer. Auto Scaling groups combined with an Elastic Load Balancer allow dynamic, automated scaling to handle load spikes efficiently.

Q: In a high-traffic production environment using AWS Lambda, which approach would best prevent throttling issues due to concurrent executions?

Correct answer: Use reserved concurrency settings to allot a dedicated pool for the function. Using reserved concurrency ensures that a Lambda function has a guaranteed number of executions, which prevents system-wide throttling during traffic spikes.

Q: What approach do you take when tasked with learning a new technical concept or tool in AWS?

Why it matters: Evaluates learning agility and self-directed problem solving. What to listen for: Green flags: References official documentation, building prototype sandboxes, writing tests, and asking structured questions.

Q: Describe a complex technical bottleneck you resolved in AWS. What was the root cause?

Why it matters: Evaluates real-world optimization and diagnostics capability. What to listen for: Green flags: Uses profiling tools, isolates latency sources, measures before and after, and documents lessons learned.

Q: How do you evaluate architectural trade-offs when designing high-throughput systems in AWS?

Why it matters: Evaluates architectural pragmatism over hype-driven development. What to listen for: Green flags: Evaluates operational complexity, network latency, data consistency (CAP theorem), and organizational fit.

Q: When deploying a static website on AWS, which service provides an easy and cost-effective solution with global content delivery and HTTPS support?

Correct answer: Amazon S3 with Amazon CloudFront. Using Amazon S3 for storage and CloudFront for content delivery is a best practice for hosting static websites securely and cost-effectively.

Q: When designing a serverless application that requires asynchronous processing, which AWS service integration is best suited to decouple task submission from processing?

Correct answer: Use Amazon SQS in combination with AWS Lambda. Integrating Amazon SQS with AWS Lambda decouples the tasks from processing and efficiently handles asynchronous workloads.

Q: When migrating a legacy on-premise application to AWS with minimal downtime, which approach leverages modern practices while ensuring a smooth transition?

Correct answer: Employ AWS Server Migration Service for incremental replication. AWS Server Migration Service facilitates incremental migration with minimal downtime, allowing legacy applications to be transitioned to AWS reliably.

Q: Describe a difficult bug you encountered in a recent project and how you solved it.

Why it matters: Evaluates systematic debugging process. What to listen for: Green flags: Uses logs, debuggers, isolation techniques, and root-cause analysis.

Hiring Workflow, Step by Step

Every stage of this hire can run in SkillSauce on one board, from the first applicant to the offer. The level sections below add the detail for junior (0-3 years), mid-level (3-6 years) and senior (6+ years) hires.

1
Open a Job Profile for the role
Create a Job Profile for the role: one Kanban board, free on every plan, that holds every candidate, test and interview for this hire. Write the job description with the free Job Description Generator, or start from the template in your level below.
2
Fill the candidate pool
Publish the job on your Career Page and share the link on LinkedIn, X and job boards, so every applicant lands on the board. To reach people who have not applied, search Candidate Lookup by domain and seniority, then narrow by industry, company and location. You can also import LinkedIn profiles by URL, upload resumes in bulk or import a CSV.
3
Shortlist the strongest resumes
Move applicants into the Resume Shortlister: TESSA AI scores every resume against the Job Profile and shows its reasoning, so you can see why each candidate made the cut before you send a single test.
4
Test the skills the role needs
Send the shortlist an IT assessment on AWS, Cloud Architecture and RDS. Build it from the Question Library of 320,000+ questions, or let TESSA AI generate it when your exact skill mix is missing, and keep AI proctoring on for remote candidates.
5
Interview with TESSA AI
Invite the candidates who pass to a TESSA AI interview on the role itself, in any of 100+ languages. Add a Culture Fit round to see how they work with a team like yours, and a Behavioural round for senior hires, where judgment and ownership matter most.
6
Meet the shortlist
Schedule the live interviews on Zoom or Google Meet with Google Calendar invites, and keep candidates posted on WhatsApp or email.
7
Decide together and make the offer
Compare finalists on their Reports: scored results for each test and AI interview, plus the proctoring activity of proctored tests. Collect your hiring team’s feedback on each candidate, then make the offer with the email templates in your level below.
