Summary

Went through two rounds with Applied Intuition and the second one was genuinely one of the worst interview experiences I've had. The interviewer showed up late, spent most of the session making snide comments about my system design, and cut the whole thing short. Rejection came right after, which, yeah, not a shock.

Suggested Approach

Start by clarifying the problem's functional and non-functional requirements, then sketch a high-level design before diving into component details. Iterate through scalability, trade-offs, and bottlenecks, and always tie decisions back to the requirements and constraints.

Pro tip: Drive the conversation by stating your assumptions explicitly and asking the interviewer to confirm them—this shows collaboration and prevents you from solving the wrong problem. Also, proactively discuss trade-offs and alternatives, not just your chosen solution.

1. Clarify Requirements

Ask questions to understand the problem's scope, functional requirements (e.g., features, users), and non-functional requirements (e.g., scale, latency, consistency, availability).

2. High-Level Design

Sketch the main components (e.g., clients, servers, databases, caches, queues) and how they interact. Keep it abstract and focus on data flow.

3. Deep Dive into Components

Elaborate on critical components: data storage (SQL vs NoSQL), APIs, scaling strategies (sharding, replication), and handling bottlenecks.

4. Address Trade-offs and Bottlenecks

Discuss trade-offs (e.g., consistency vs availability, latency vs cost) and identify potential bottlenecks (e.g., single points of failure) with mitigation strategies.

5. Summarize and Iterate

Recap the design, highlight how it meets requirements, and suggest improvements or next steps based on feedback.

Key Points to Mention

  • Scalability (horizontal vs vertical scaling, sharding, partitioning)
  • Data storage choices (SQL vs NoSQL, CAP theorem, indexing)
  • Caching strategies (CDN, Redis, Memcached) and when to use them
  • Load balancing and fault tolerance (redundancy, failover)
  • API design and communication protocols (REST, gRPC, message queues)
  • Monitoring, logging, and deployment considerations
