Hi everyone,
As announced in the last session, we're starting our Microservices Interview Preparation session today (27th August) for 5 year subscribers.
This is a 2 part session with the next session happening next Thursday.
We will discuss the Top 25 Microservices interview questions with practical examples and demos. These questions are based on real interview experiences shared by our C# Developer Community.
1. What are Microservices? Explain Microservices architecture. (TCS, INFY, CTS, CAP, WIP, VIR, LTI, ACN, GL)
2. What is the difference between Monolithic and Microservices architecture? (TCS, INFY, CTS, CAP, WIP, VIR, GL, LTI, PER)
3. How do Microservices communicate with each other? (CTS, GL, VIR, EPAM, DEL, TCS)
4. Synchronous vs Asynchronous communication in Microservices? (CTS, EPAM, DEL, VIR)
5. REST API vs Message Queue/Event Bus — when would you use each? (VIR, CTS, GL)
6. What are the advantages and disadvantages/challenges of Microservices? (INFY, CTS, VIR, CAP)
7. How do you identify or define Microservice boundaries? (VIR, EPAM, DEL)
8. What is Domain-Driven Design (DDD), and how is it related to Microservices? (EPAM, DEL, PS)
9. What is a Bounded Context and how does it help define Microservices? (EPAM, TW, DEL)
10. What is an API Gateway and why is it required? (CTS, TCS, ACN, EPAM, CAP)

13. What is the Saga Pattern? (EPAM, DEL, ACN, CTS, VIR)
14. Saga Choreography vs Orchestration? (EPAM, DEL, ACN, CTS)
15. What is CQRS and why/when would you use it? (EPAM, DEL, PS, ACN)
16. How do you maintain data consistency / eventual consistency across Microservices? (CTS, GL, EPAM, DEL)
17. How do you handle failures and fault tolerance in Microservices? (GL, CTS, INFY, EPAM)
18. Explain Retry and Circuit Breaker patterns. (INFY, CTS, EPAM, ACN, CAP)
