Example Technical Interview Questions and Answers

Practice makes perfect. Use these examples as inspiration for crafting your own answers:

Question: Explain the difference between SQL and NoSQL databases.

Strong Answer: “SQL databases are relational databases that use a structured schema to store data. They are well-suited for applications that require data integrity and consistency. NoSQL databases, on the other hand, are non-relational databases that offer more flexibility and scalability. They are often used for applications that need to handle large volumes of unstructured data. A good example is choosing a SQL database for financial transactions where accuracy is key, versus a NoSQL database for a social media feed where speed and scalability are more critical.”

Question: How would you design a scalable API?

Strong Answer: “To design a scalable API, I would focus on several key aspects. First, I’d ensure the API is stateless, meaning each request contains all the information needed for processing, avoiding server-side sessions. Second, I’d implement caching mechanisms to reduce the load on the backend servers. Third, I’d use a load balancer to distribute traffic across multiple servers. Finally, I’d monitor the API’s performance and scale resources as needed. For example, if we’re building an API for an e-commerce platform, we’d use a CDN to cache product images and API responses, reducing latency and improving the user experience.”

Question: What are the key considerations when choosing a cloud provider?

Strong Answer: “When choosing a cloud provider, I would consider factors such as cost, performance, security, and compliance. Cost is a major consideration, as different providers offer different pricing models. Performance is also important, as the cloud provider should be able to meet the application’s performance requirements. Security is critical, as the cloud provider should have robust security measures in place to protect data. Compliance is also a factor, as the cloud provider should comply with relevant regulations. For instance, a healthcare company needs a cloud provider compliant with HIPAA, while a financial institution needs one compliant with PCI DSS.”
