rollbacks in AWS Amplify?
An ideal candidate should explain the version
control features offered by Amplify and how they can be utilized to manage
application deployments. They should mention techniques like creating branches for
development, testing, and production environments, and rolling back to previous
versions if necessary.
Suppose an application built using AWS Amplify
experiences performance issues. How would you investigate and troubleshoot the
problem?
Look for candidates who mention utilizing AWS
Amplify's monitoring and logging capabilities, such as CloudWatch logs and metrics.
They should discuss analyzing performance metrics, identifying bottlenecks, and
leveraging Amplify's debugging tools to troubleshoot issues related to API calls,
data storage, or authentication.
Describe how you would implement continuous
integration and continuous deployment (CI/CD) for an application built with AWS
Amplify.
The candidate should discuss their experience
with CI/CD pipelines and mention how they would integrate AWS Amplify with popular
CI/CD tools like AWS CodePipeline or Jenkins. They should highlight the steps
involved in automating the build, test, and deployment processes, ensuring efficient
and reliable application delivery.
Tell us about a project where you had to collaborate
with a cross-functional team while using AWS Amplify. How did you ensure effective
communication and successful project delivery?
Look for candidates who emphasize their
teamwork skills, ability to coordinate efforts with designers, backend developers,
or other stakeholders. They should discuss their communication strategies, including
regular meetings, task tracking, and leveraging collaborative tools to ensure smooth
collaboration throughout the project.
Describe a situation where you encountered a
challenging issue while working with AWS Amplify. How did you handle it?
The candidate should discuss their
problem-solving skills, ability to research documentation and online resources, and
their approach to troubleshooting. Look for answers that highlight their
perseverance, initiative, and ability to seek assistance when needed to resolve
complex issues.
How do you stay up-to-date with the latest
advancements and best practices in AWS Amplify?
A strong candidate should mention their
dedication to continuous learning, attending webinars or conferences, following AWS
blogs or developer communities, and actively participating in relevant online
forums. They should emphasize their ability to adapt to new features and best
practices within the evolving AWS Amplify ecosystem.
Describe a situation where you had to make
architectural decisions while developing an application using AWS Amplify. How did
you ensure scalability, security, and cost-efficiency?
Look for candidates who demonstrate a deep
understanding of AWS Amplify's architectural principles. They should discuss their
approach to designing a scalable and secure architecture, utilizing services like
AWS Lambda, Amazon API Gateway, and AWS Identity and Access Management (IAM). They
should also mention techniques for optimizing costs, such as leveraging serverless
computing or implementing efficient data storage strategies.
How do you handle feedback or suggestions from team
members or stakeholders during the development process?
The candidate should emphasize their ability
to receive feedback constructively, adapt to changes, and collaborate effectively
with team members. They should discuss their approach to actively seeking feedback,
addressing concerns or suggestions, and maintaining a positive and collaborative
mindset throughout the iterative development process.
