Examples of Technical IT Interview Questions and Answers in Germany

Full-Stack Developer:

Question: Explain the difference between SQL and NoSQL databases.
Answer: SQL databases are relational databases that use structured query language (SQL) for data manipulation. They have a predefined schema and use tables to store data. NoSQL databases are non-relational and don’t use SQL for data manipulation. They have a dynamic schema and can store unstructured data in various formats such as key-value, document, column-family, or graph stores.

Backend Developer:

Question: What is the difference between a RESTful API and a GraphQL API?
Answer: A RESTful API follows a representational state transfer (REST) architecture and uses standard HTTP methods to interact with resources. It usually returns data in JSON or XML format. A GraphQL API, on the other hand, is a query language for APIs that allows the client to request only the data it needs, reducing over-fetching or under-fetching of data. GraphQL enables more precise control over data retrieval and manipulation.
