What is an API gateway?
Once the interviewer begins to ask questions about a certain topic, they may proceed to ask similar questions. These can be a standalone question or a follow-up of their original inquiry. By doing this, the interviewer indicates that the topic they are asking about is important to the organization. They seek to confirm your understanding of the topic and explore your knowledge in this area. It is not unusual for an interviewer to remain on a single topic for a long time or even for a large portion of the interview. This may occur if the hiring manager has indicated that the person who previously held this job had a problem in this area.
Regardless of how many times an interviewer asks you about the same topic, you should continue to answer in a calm, consistent manner. Keep your answer direct and to the point, and anticipate a follow-up question. Always remember to use simple, easy-to-understand language during an interview since you are not aware of the technical competence of all the interviewers. If you sense that the interviewer does not understand your responses, you can ask a clarifying question or offer to explain the answer differently.
"An API gateway is a tool that sits between a web client and the website's backend services. It acts as a reverse proxy, accepting all application programming interface calls, routing them to the web services required to fulfill them, and returning the appropriate results. API gateways can access all the website's resources, but typically interact with microservices in the web architecture."
