Preview List
1. Implement an LRU Cache
Why you might get asked this:
This question tests your understanding of data structures (hash maps, doubly linked lists) and your ability to design an efficient caching system with O(1) average time complexity for get
and put
operations.
How to answer:
Use a hash map to store key-node pairs for O(1) lookup. Use a doubly linked list to maintain recency, placing recently used items at the front and evicting from the tail.
Example answer:
"I would implement an LRU cache using a hash map to store key-value pairs (where value is a node in a doubly linked list) and a doubly linked list to manage the order of usage. get
operations update node position to the front; put
operations add/move nodes to front and evict the least recently used from the tail if capacity is exceeded, ensuring O(1) performance."
2. Binary Search Variants
Why you might get asked this:
This assesses your ability to apply a fundamental algorithm, handle edge cases, and adapt to variations like finding first/last occurrences, or elements greater/smaller than a target.
How to answer:
Clearly define search space left
and right
pointers. Adjust them based on comparison. Pay close attention to conditions for mid
calculation and loop termination to avoid off-by-one errors and infinite loops.
Example answer:
"Binary search is ideal for sorted arrays. The key is correctly adjusting low
and high
pointers, and handling the mid
calculation (low + (high - low) / 2
). For variants, like finding the first occurrence, I'd refine the condition to continue searching left even on a match, storing the result."
3. Graph Traversals (DFS, BFS)
Why you might get asked this:
Graphs are ubiquitous in AI (e.g., knowledge graphs, neural networks). This tests your understanding of fundamental search algorithms and their application in various scenarios.
How to answer:
Explain DFS (stack/recursion, depth-first exploration) and BFS (queue, level-by-level exploration). Discuss their use cases (e.g., shortest path with BFS, topological sort with DFS). Provide pseudocode for one.
Example answer:
"DFS uses a stack (or recursion) to explore as far as possible along each branch before backtracking; useful for cycle detection or topological sort. BFS uses a queue to explore neighbors level by level; ideal for shortest path in unweighted graphs. I'd typically use an adjacency list for graph representation."
4. Design an In-Memory Database
Why you might get asked this:
This tests your understanding of data structures, concurrency, transaction management (ACID properties), and system design principles for low-latency data storage.
How to answer:
Discuss using hash maps for storage, B-trees for indexing. Address concurrency (locks, MVCC), transaction isolation (snapshots), and persistence mechanisms (WAL). Emphasize simplicity for in-memory.
Example answer:
"For an in-memory database, I'd use hash maps for efficient key-value storage. To support transactions, I'd consider Multi-Version Concurrency Control (MVCC) for non-blocking reads. Write-Ahead Logging (WAL) would be used for durability to recover state on restart. Data structures like skip lists or B-trees could support range queries effectively."
5. Versioned Data Stores
Why you might get asked this:
OpenAI often deals with evolving models and data. This assesses your ability to design systems that track changes, allow rollbacks, and provide historical querying.
How to answer:
Explain storing data alongside a version identifier (e.g., timestamp, commit ID). Discuss strategies like storing deltas, full copies, or using a log-structured merge-tree (LSM-tree) architecture.
Example answer:
"A versioned data store requires associating data with a timestamp or version ID. One approach is to append new versions rather than overwriting, using a log-structured store. Queries would then specify a version or retrieve the latest. Garbage collection for old versions would be necessary based on retention policies."
6. Time-Based Key-Value Store
Why you might get asked this:
This combines key-value store concepts with temporal querying, relevant for applications needing to retrieve data as it existed at a specific point in time.
How to answer:
For each key, store a sorted list of (timestamp, value) pairs. When queried for a key at a specific timestamp, perform a binary search on the list to find the appropriate version.
Example answer:
"For a time-based key-value store, each key would map to a sorted list of (timestamp, value)
tuples. When get(key, timestamp)
is called, I'd use binary search on that list to find the largest timestamp less than or equal to the query timestamp, returning its associated value. put(key, value, timestamp)
would insert into the sorted list."
7. Concurrency Problems (Coroutines, Threads)
Why you might get asked this:
High-performance AI systems require efficient resource utilization and parallel processing. This tests your understanding of concurrent programming paradigms and safe resource sharing.
How to answer:
Discuss threads vs. coroutines, their respective overheads and use cases (CPU-bound vs. I/O-bound). Explain common issues (race conditions, deadlocks) and solutions (locks, semaphores, message passing).
Example answer:
"Concurrency problems arise from shared mutable state. For threads, I'd use locks or mutexes to protect critical sections, or concurrent data structures. Coroutines are more suited for I/O-bound tasks, offering cooperative multitasking without thread overhead. The producer-consumer pattern can be solved using queues with appropriate synchronization."
8. Recursive Backtracking
Why you might get asked this:
Many combinatorial optimization and search problems, common in AI planning and constraint satisfaction, can be elegantly solved using backtracking.
How to answer:
Explain backtracking as a systematic way to explore all possible solutions by building candidates incrementally. If a partial solution violates constraints, abandon it and backtrack. Define base cases and recursive steps.
Example answer:
"Recursive backtracking is a general algorithm for solving problems that incrementally build a solution, removing candidates that fail to satisfy constraints. It typically involves a recursive function that tries to add one piece to the current solution. If it works, recurse; otherwise, undo the change and try another option. Base cases define a complete solution or a dead end."
9. Object-Oriented Programming (OOP) Design
Why you might get asked this:
This evaluates your ability to structure complex software with maintainability, scalability, and reusability in mind, fundamental for large codebases like those at OpenAI.
How to answer:

Example answer:
"OOP emphasizes organizing code around objects with data and behavior. Encapsulation hides internal state, inheritance promotes code reuse, and polymorphism allows flexible method calls. I'd use abstraction to define clear interfaces. This promotes modularity and makes systems easier to maintain and scale, especially in a large project like an OpenAI model."
10. Algorithm Optimization for Latency
Why you might get asked this:
In AI, especially with LLMs, inference latency is critical for user experience. This tests your practical understanding of optimizing algorithms for real-world performance constraints.
How to answer:
Discuss identifying bottlenecks (profiling), optimizing data structures, reducing redundant computations, using caching, and leveraging parallelism (GPU/TPU acceleration if applicable). Mention algorithmic complexity.
Example answer:
"Optimizing for latency involves profiling to find bottlenecks. I'd first analyze the algorithm's time complexity. Techniques include choosing more efficient data structures, memoization/caching intermediate results, parallelizing computations, and optimizing low-level operations. For LLMs, this might involve quantization, pruning, or model distillation to reduce inference time without significant accuracy loss."
11. Dynamic Programming Problems
Why you might get asked this:
DP is crucial for optimization problems where subproblems overlap, common in sequence modeling, bioinformatics, and some AI planning tasks.
How to answer:
Explain DP's two key properties: overlapping subproblems and optimal substructure. Describe both memoization (top-down) and tabulation (bottom-up) approaches, providing a simple example like Fibonacci.
Example answer:
"Dynamic Programming solves complex problems by breaking them into simpler overlapping subproblems and storing their solutions to avoid recomputation. This can be done top-down with memoization or bottom-up with tabulation. The optimal substructure property means an optimal solution to the problem can be constructed from optimal solutions of its subproblems."
12. Tree Traversal Algorithms
Why you might get asked this:
Trees are fundamental data structures (e.g., parse trees in NLP, decision trees in ML). This assesses your knowledge of how to navigate and process data within them.
How to answer:
Explain In-order, Pre-order, and Post-order traversals for binary trees, describing when each is useful. Mention level-order (BFS) for tree structures. Provide recursive or iterative implementations.
Example answer:
"Tree traversals systematically visit nodes. Pre-order (root, left, right) is useful for creating a copy or expressing prefix notation. In-order (left, root, right) for sorted output of a BST. Post-order (left, right, root) for deleting nodes or evaluating postfix expressions. BFS/level-order traverses layer by layer."
13. String Manipulation Challenges
Why you might get asked this:
String processing is common in NLP and data parsing. This tests your ability to handle text efficiently, considering edge cases, character sets, and performance.
How to answer:
Discuss various string operations (substring, concatenation, regex) and efficient algorithms (KMP for pattern matching, dynamic programming for edit distance). Emphasize immutability and potential performance issues.
Example answer:
"String manipulation often involves common operations like searching, replacing, or parsing. Efficiency is key; for example, avoiding repeated string concatenation in loops. I'd consider using optimized library functions or specific algorithms like KMP for pattern searching, or dynamic programming for tasks like longest common subsequence, ensuring edge cases are handled."
14. Sorting Algorithms Analysis/Implementation
Why you might get asked this:
While often solved by library functions, understanding sorting algorithms (Quicksort, Mergesort, Heapsort) demonstrates foundational CS knowledge and complexity analysis skills.
How to answer:
Describe the principles of a few key sorting algorithms (e.g., Quick Sort, Merge Sort, Heap Sort), their time/space complexities, stability, and when to choose one over another.
Example answer:
"Merge Sort is stable and has O(N log N) worst-case time complexity, but uses O(N) space. Quick Sort is typically faster in practice (O(N log N) average) but O(N^2) worst-case and unstable. Heap Sort is O(N log N) in-place. The choice depends on data size, stability requirements, and memory constraints."
15. Bit Manipulation Techniques
Why you might get asked this:
This tests your ability to perform low-level optimizations, understand data representation, and solve problems efficiently using bitwise operations, useful in specific performance-critical contexts.
How to answer:
Explain common bitwise operators (AND, OR, XOR, NOT, shifts). Provide examples of their use in tasks like checking/setting bits, counting set bits, or optimizing arithmetic operations.
Example answer:
"Bit manipulation is about operating directly on the binary representation of numbers using operators like AND, OR, XOR, NOT, and shifts. It's useful for low-level optimizations, flag management, or solving problems efficiently like checking if a number is a power of two (n & (n-1) == 0
) or counting set bits."
16. Design an LLM-Powered Enterprise Search System
Why you might get asked this:
This is a core system design question at OpenAI, testing your ability to integrate LLMs into complex, scalable applications and address real-world challenges like indexing, latency, and cost.
How to answer:
Outline components: data ingestion, embedding generation (with vector DB), semantic search (retrieval augmented generation/RAG), LLM for synthesis/summarization, caching, monitoring. Discuss scalability, latency, and cost considerations.
Example answer:
"I'd design it with data ingestion, chunking, and embedding generation stored in a vector database. User queries would be embedded and used for similarity search to retrieve relevant text chunks (RAG). These chunks, along with the query, would prompt an LLM for response synthesis. Caching embeddings and responses, plus asynchronous processing, would optimize performance. Security and access control are also crucial."
17. High-Scale Distributed Systems Design
Why you might get asked this:
OpenAI operates at a massive scale. This question assesses your understanding of distributed computing principles, fault tolerance, consistency, and scalability strategies.
How to answer:
Discuss CAP theorem, consistency models (strong, eventual), partitioning/sharding, replication, load balancing, fault detection, and recovery mechanisms. Use examples like Kafka, Cassandra, or Kubernetes.
Example answer:
"Designing high-scale distributed systems requires balancing consistency, availability, and partition tolerance. I'd consider data partitioning (sharding) for scalability, replication for fault tolerance, and load balancing for request distribution. Choosing the right consistency model, employing distributed consensus (e.g., Raft), and designing for failure are paramount to ensuring robustness."
18. Realtime Data Pipeline Design
Why you might get asked this:

Example answer:
"For a real-time data pipeline, I'd use Kafka for high-throughput ingestion and buffering. Stream processing frameworks like Apache Flink or Spark Streaming would handle transformations, aggregations, and enrichments with low latency. Data would then be loaded into a fast query store, like a time-series database or an in-memory cache, ensuring fault tolerance and monitoring throughout."
19. Experience with LLMs and Fine-Tuning
Why you might get asked this:
Direct experience with LLMs is highly valued. This probes your practical skills in applying, adapting, and optimizing large models for specific tasks.
How to answer:
Describe specific projects where you worked with LLMs. Detail prompt engineering, dataset preparation, fine-tuning techniques (LoRA, QLoRA), evaluation metrics, and optimization challenges (latency, cost, bias).
Example answer:
"I've fine-tuned GPT-style models for domain-specific tasks, focusing on prompt engineering to elicit desired behaviors and creating high-quality datasets for fine-tuning. I've experimented with LoRA for efficient adaptation and optimized inference latency through techniques like quantization and model distillation, always evaluating for performance and potential biases."
20. Handling Ambiguity in Requirements
Why you might get asked this:
AI research and product development often involve ill-defined problems. This tests your ability to navigate uncertainty, ask clarifying questions, and iterate.
How to answer:
Explain your process: ask clarifying questions, identify assumptions, break down the problem, propose iterative solutions, communicate trade-offs, and seek feedback early. Emphasize a structured yet flexible approach.
Example answer:
"When faced with ambiguous requirements, my first step is to ask clarifying questions to narrow down the scope and identify key constraints. I'd then propose a minimal viable solution, outlining my assumptions, and iterate closely with stakeholders. This iterative approach allows for course correction and ensures alignment as understanding evolves, reducing risk."

Example answer:
"Attention mechanisms allow models to focus on relevant parts of the input sequence. Self-attention, as used in Transformers, calculates a weighted sum of input values, where weights are determined by the similarity between a query and keys. Multi-head attention performs this process in parallel, allowing the model to capture diverse relationships and long-range dependencies effectively."
22. Explain Backpropagation and Gradient Descent
Why you might get asked this:
These are the foundational algorithms for training neural networks. You must demonstrate a deep understanding of how models learn.
How to answer:
Explain gradient descent as an iterative optimization algorithm that minimizes a loss function by moving in the direction of the steepest descent. Describe backpropagation as the method to calculate these gradients efficiently using the chain rule.
Example answer:
"Gradient Descent is an optimization algorithm that iteratively adjusts model parameters to minimize a loss function by moving in the direction opposite to the gradient. Backpropagation is the algorithm that computes these gradients efficiently through the network using the chain rule, propagating errors backwards from the output layer to update weights in each layer."
23. Feature Engineering Strategies
Why you might get asked this:
Effective feature engineering can significantly improve model performance, especially in traditional ML settings or when preparing data for deep learning.
How to answer:
Discuss techniques like creating interaction terms, polynomial features, binning, one-hot encoding, target encoding, and dimensionality reduction. Emphasize domain knowledge and iterative experimentation.
Example answer:
"Feature engineering involves transforming raw data into features that better represent the underlying problem to the model. Strategies include creating interaction terms, polynomial features, handling categorical data with one-hot or target encoding, and using aggregation or time-based features. It's often an iterative process requiring domain expertise and experimentation to find optimal representations."
24. Model Evaluation Metrics
Why you might get asked this:
Properly evaluating models is critical for selecting the best performing ones and understanding their limitations. This tests your ability to choose and interpret relevant metrics.
How to answer:
Discuss common metrics for different tasks (e.g., accuracy, precision, recall, F1-score, ROC-AUC for classification; RMSE, MAE, R-squared for regression). Explain their trade-offs and when to use each.
Example answer:
"For classification, I consider precision and recall (and F1-score) over pure accuracy, especially for imbalanced datasets. ROC-AUC gives a comprehensive view of classifier performance across thresholds. For regression, RMSE (root mean squared error) or MAE (mean absolute error) are standard. The choice of metric heavily depends on the business objective and data characteristics."
