AI-powered Software Architect mock interviews

Design a scalable and fault-tolerant system architecture for a real-time chat application with millions of concurrent users. Discuss the key components, data storage strategy, and potential bottlenecks.

Explain how you would design a microservices architecture for a high-traffic e-commerce platform. Discuss the communication protocols between microservices, data consistency strategies, and ways to handle service failures.

How would you design a communication protocol between microservices to ensure efficient and reliable data exchange while considering factors like latency, message formats, and error handling mechanisms?

Can you explain the concept of service discovery in the context of microservices architecture and discuss its importance in ensuring scalability and fault tolerance?

Discuss the trade-offs between using an array and a linked list to implement a priority queue. In what scenarios would you prefer one over the other?

Explain the difference between a stack and a queue. Provide a real-world example where you would use each data structure.

Explain the difference between Dijkstra's algorithm and A* search algorithm. When would you choose one over the other?

Describe how you would optimize a recursive algorithm using dynamic programming. Provide an example scenario where this optimization would be beneficial.

Describe a situation where you had to communicate a complex idea to a non-technical stakeholder. How did you ensure effective communication and understanding? What strategies did you use to overcome any potential misunderstandings?

Can you provide an example of a time when you had to navigate a challenging team dynamic to successfully deliver a project? How did you approach the situation and what was the outcome?
