10 Priority Practice Questions
Offer.cc editorial practice exercises; they are not an official company question bank or actual interview questions.
Use a shopping cart as a system design exercise: discuss the data model, pricing, inventory checks, sessions, persistence, and scaling options for a hypothetical traffic spike. State constraints, trade-offs, and failure paths.
QuickSelect for average O(n) or min-heap of size K for O(n log K). Discuss when each approach is preferred.
STAR format. Focus on respectfully challenging the decision with data, the resolution process, and what you learned.
Model as a directed graph. Use Kahn's algorithm (BFS) or DFS with cycle detection. Return order or detect impossibility.
Use an event-driven design to practice order states, payment processing, inventory reservation, and idempotency. Compare queues and pub-sub patterns without assuming a specific internal service.
Use a hash map to locate nodes and a doubly linked list to maintain recency. Explain node movement, updates to existing keys, and eviction while you code.
STAR format. Show initiative — don't say 'it wasn't my job'. Emphasize cross-team impact and long-term thinking.
Build a Trie from the word list. DFS on the board using the Trie for pruning. Remove found words to avoid duplicates.
Practice Base62 encoding, distributed storage, and edge caching. Discuss expiration, custom aliases, collision handling, and observability.
STAR format. Show how you identified unnecessary complexity, proposed a simpler solution, and measured the improvement.
Common Mistakes to Avoid
Section sources [1] SDE II Interview Prep [2] Software Development Interview Topics
Treating practice prompts as a fixed question bank
The prompts train problem solving, communication, and trade-offs; they do not claim that the company asks the same questions. Practice transferable methods instead of memorizing answers.
Giving a conclusion without trade-offs
State assumptions, explain why you chose an approach, and name alternatives. Ask for clarification when information is missing so the reasoning remains useful across questions.
Skipping edge cases and validation
After answering, check input boundaries, failure paths, complexity, and engineering constraints. Validate the approach with one concrete example and correct any gap you find.
Not checking the latest role instructions
Roles, teams, and recruiting arrangements change. Recheck the official role sources before the interview and follow the recruiter’s latest instructions for language, tools, and process.
