• Authentication vs. Authorization: A question on authentication, which the candidate initially confused with authorization.
• DBMS: "What are ACID properties and their meaning?" and "What is an entity in the ER Diagram?"

Overall Experience: The candidate felt relieved to be asked about cloud computing, which they could answer. They also felt proficient in JavaScript and DBMS topics. The interview seemed to cover a mix of technical knowledge and project-specific discussions.
