10 Priority Practice Questions
Offer.cc editorial practice exercises; they are not an official company question bank or actual interview questions.
Use LinkedHashMap directly or combine a hash map with a doubly linked list. Explain how get, put, and eviction remain O(1). Then discuss a thread-safe design with ConcurrentHashMap and locks.
Practice pub-sub, quote aggregation, and compression. Define latency and throughput targets before comparing queues, consistency, and recovery options.
BFS for unweighted graph shortest path. Variant: shortest path with K obstacle eliminations. Use state (row, col, obstacles_left) for BFS.
Order, OrderBook, Trade, Instrument class hierarchy. Discuss limit vs market orders, order lifecycle, and state machine design.
Use stacks for repeat counts and the string that precedes each opening bracket. On a closing bracket, pop, expand, and append the segment. Cover nested input, empty strings, and malformed syntax.
Buy/sell order books, price-time priority matching. Discuss data structure choices (red-black tree/heap), performance optimization, and fairness guarantees.
Maintain the best sum ending at the current position and the global best. Extend the exercise to return subarray bounds and handle a circular array. Explain initialization for an all-negative input.
synchronized vs ReentrantLock, volatile, ConcurrentHashMap, ThreadPoolExecutor. Discuss deadlock prevention and producer-consumer patterns.
Batch VaR (Value at Risk) calculation. Discuss Monte Carlo simulation, parallel computation, data partitioning, and result caching strategies.
Atomicity, Consistency, Isolation, Durability. Explain why each matters using financial transaction scenarios. Discuss isolation level trade-offs.
Common Mistakes to Avoid
Section sources [3] Your Guide to HackerRank Success
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.
