Real-World Examples of Technical IT Interview Questions and Answers for Various IT Roles in Germany
Front-end Developer:
Question: How would you optimize a website’s performance?
Answer: I would use techniques such as minimizing HTTP requests, compressing files, enabling browser caching, minifying CSS and JavaScript files, optimizing images, and using a Content Delivery Network (CDN) to improve the website’s loading speed.
IT Support:
Question: How would you troubleshoot a slow computer?
Answer: I would first check for any hardware issues, such as insufficient RAM or hard drive space. Next, I would look for software-related issues, including outdated drivers, malware, or a high number of startup programs. I would also investigate the computer’s settings, including power management options and visual effects, to identify any potential optimizations.
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.
