How to Find Full Stack Developer Jobs in the Netherlands for English-Speakers
Top 5 Technical Interview Questions Asked to Full Stack Developer
- Purpose: This question assesses your understanding of API design and data fetching strategies.
- Answer Focus: REST is a traditional API design that relies on endpoints corresponding to different resources. GraphQL, on the other hand, allows clients to request only the data they need through a single endpoint, offering more flexibility and efficiency. You should discuss scenarios where each would be appropriate, such as REST for simpler, well-defined resources, and GraphQL for complex data retrieval needs with multiple nested relationships.
- Purpose: This tests your understanding of how JavaScript handles events, which is crucial for optimizing front-end performance.
- Answer Focus: Event delegation allows you to attach a single event listener to a parent element to manage events triggered by its child elements. This is efficient because it reduces the number of event listeners needed, especially in dynamic content. You might explain how event bubbling works and how event delegation leverages it.
- Purpose: This question evaluates your knowledge of database management and your ability to choose the right tool for the job.
- Answer Focus: SQL databases are relational and use structured query language for defining and manipulating data, making them ideal for complex queries and structured data. NoSQL databases are non-relational and can handle unstructured or semi-structured data, offering flexibility and scalability. You should discuss use cases such as SQL for financial records and NoSQL for handling large volumes of data like social media feeds.
- Explain the concept of “Promises” in JavaScript and how they differ from callbacks.
- Purpose: This question checks your knowledge of DevOps practices and your ability to automate deployment processes.
- Answer Focus: A CI/CD pipeline automates the process of code integration, testing, and deployment. You should outline steps such as setting up a version control system (e.g., Git), using a CI tool (e.g., Jenkins, GitLab CI), automating testing, and deploying the application to a staging or production environment using tools like Docker and Kubernetes. Highlight the benefits of CI/CD in improving deployment frequency and reliability.
