Communication may vary, so staying proactive with follow-ups is beneficial.

Now, let’s dive into the types of interview questions you can expect at each stage.

3.1. Algorithms & Data Structures

Expect questions that test your ability to design and implement efficient algorithms and data structures, focusing on both correctness and performance. You should be comfortable translating real-world scenarios into code and explaining your approach. Interviewers will look for clarity in logic, optimal time/space complexity, and clean communication of trade-offs.

3.1.1 Implementing a priority queue used linked lists
Briefly describe how you would create a priority queue using a linked list, focusing on insert and remove operations. Discuss how you maintain order and optimize for speed.
Example answer: "I'd use a singly linked list and insert elements in sorted order to maintain priority. Removal would always take from the head, ensuring the highest-priority item is served first."

3.1.2 The task is to implement a shortest path algorithm (like Dijkstra's or Bellman-Ford) to find the shortest path from a start node to an end node in a given graph. The graph is represented as a 2D array where each cell represents a node and the value in the cell represents the cost to traverse to that node.
Discuss your approach for choosing the algorithm, handling edge cases, and optimizing for time/space.
Example answer: "I'd use Dijkstra's algorithm for non-negative weights, maintaining a min-heap for efficient selection of the next node, and track visited nodes to avoid cycles."

3.1.3 Given an array of non-negative integers representing a 2D terrain's height levels, create an algorithm to calculate the total trapped rainwater. The rainwater can only be trapped between two higher terrain levels and cannot flow out through the edges. The algorithm should have a time complexity of O(n) and space complexity of O(n). Provide an explanation and a Python implementation. Include an example input and output.
Explain how you would approach the problem using two-pointer or stack-based methods, and justify your complexity claims.
Example answer: "I'd iterate from both ends, keeping track of left and right max heights, and accumulate water trapped at each position based on the minimum of the two."

3.1.4 Create a binary tree from a sorted list.
Describe how you would construct a balanced binary search tree, emphasizing recursion and base cases.
Example answer: "I'd recursively select the middle element as the root, then build left and right subtrees from the remaining halves to ensure balance."

3.1.5 Implement a basic LRU cache.
Summarize how you would design an LRU cache using appropriate data structures to ensure O(1) access and eviction.
Example answer: "I'd combine a doubly linked list for order and a hash map for quick lookup, updating the list on every access and removing the least recently used item when full."

3.2. System Design & Architecture

These questions evaluate your ability to architect scalable, maintainable systems. You’ll need to demonstrate understanding of trade-offs, modularity, and reliability. Focus on communicating your design choices and how they meet business requirements.

Outline your system components, data flow, and how you’d manage scalability and reliability.
Example answer: "I'd separate user management, parking spot allocation, and payment into microservices, using a central database and caching for quick spot lookup."

3.2.2 Design a database for a ride-sharing app.
Discuss schema design, normalization, and key entities such as users, rides, and payments.
Example answer: "I'd model users, drivers, rides, and transactions as separate tables, with foreign keys for relationships and indexing for fast matching."

3.2.3 System design for a digital classroom service.
Describe your approach to supporting real-time collaboration, data privacy, and scalability.
Example answer: "I'd use a cloud-based architecture with real-time messaging, role-based access control, and sharding to support large classrooms."

3.2.4 Design a data warehouse for a new online retailer
Explain how you would structure the warehouse, ETL pipelines, and support analytics needs.
Example answer: "I'd use a star schema with fact tables for sales and dimension tables for products and customers, automating ETL for nightly updates."

3.2.5 Design a data pipeline for hourly user analytics.
Summarize your choices for data ingestion, transformation, and aggregation, ensuring reliability and scalability.
Example answer: "I'd use a streaming platform for real-time ingestion, batch jobs for hourly aggregation, and store results in a time-series database."

3.3. Machine Learning & Modeling

You’ll be asked about building, evaluating, and deploying models. Expect to discuss feature selection, metrics, and business impact. Be ready to explain your choices and how they relate to real-world problems.

3.3.1 Building a model to predict if a driver on Uber will accept a ride request or not
Describe your approach to feature engineering, model selection, and evaluating performance.
Example answer: "I'd use historical acceptance data, engineer features like time of day and location, and train a logistic regression model, validating with AUC and precision-recall."

3.3.2 Let's say that you're designing the TikTok FYP algorithm. How would you build the recommendation engine?
Discuss collaborative filtering, content-based methods, and how you’d measure success.
Example answer: "I'd blend user interaction signals with video features, train a deep learning model, and optimize for engagement and diversity in recommendations."

3.3.3 How would you differentiate between scrapers and real people given a person's browsing history on your site?
Explain your approach to feature extraction, anomaly detection, and evaluation.
Example answer: "I'd extract behavioral features like session length and page transitions, then use clustering or supervised learning to classify users."

3.3.4 Generating Discover Weekly
Summarize your method for personalizing recommendations using user history and collaborative filtering.
Example answer: "I'd aggregate user listening history, find similar users, and recommend unseen tracks, updating weekly with fresh data."

3.3.5 Designing a Fraud Detection System: There has been an increase in fraudulent transactions, and you’ve been asked to design an enhanced fraud detection system. What key metrics would you track to identify and prevent fraudulent activity? How would these metrics help detect fraud in real-time and improve the overall security of the platform?
Discuss metrics like transaction velocity, anomaly scores, and explain how you’d implement real-time detection.
Example answer: "I'd track transaction frequency, location mismatches, and use supervised models for anomaly detection, with alerts for high-risk events."

3.4. SQL & Data Manipulation

These questions assess your ability to write efficient queries, transform data, and interpret results. Be ready to explain your approach to joins, aggregations, and optimization.

3.4.1 Find how much overlapping jobs are costing the company
Explain how you’d join tables and aggregate costs for overlapping jobs.
Example answer: "I'd use window functions to identify overlaps, sum costs, and group by job type to quantify total impact."

3.4.2 Count total tickets, tickets with agent assignment, and tickets without agent assignment.
Describe your approach to conditional aggregation and filtering.
Example answer: "I'd use CASE statements to count tickets by agent status, grouping results for reporting."

3.4.3 Modifying a billion rows
Discuss strategies for efficiently updating large tables, such as batching and indexing.
Example answer: "I'd partition updates, use bulk operations, and monitor for locking issues to minimize downtime."

3.4.4 Find all users that were at some point "Excited" and have never been "Bored" with a campaign
Explain how you’d use conditional aggregation or filtering to identify qualifying users.
Example answer: "I'd group by user, filter for those with 'Excited' events and exclude any with 'Bored' events using HAVING clauses."

3.4.5 Write a query to compute the average time it takes for each user to respond to the previous system message
Describe your use of window functions to align messages and calculate time differences.
Example answer: "I'd use LEAD or LAG to pair messages, calculate response times, and aggregate by user."
