3.1.1 Design the system supporting an application for a parking system
Outline the key components, data flows, and scalability considerations for the system. Emphasize modularity, fault tolerance, and how you would handle real-time updates and user interactions.
Example answer: “I’d start by defining core modules such as user management, parking slot allocation, and payment integration. I’d use a microservices architecture to allow independent scaling and deploy real-time notifications using WebSockets for live updates.”

3.1.2 System design for a digital classroom service
Describe how you would architect a platform for virtual learning, considering user access, data storage, and interactive features. Highlight choices around technology stacks and performance optimizations.
Example answer: “I’d architect the platform with separate services for authentication, course content, and live video. For scalability, I’d use cloud storage for materials and a CDN for fast content delivery.”

3.1.3 Design a data warehouse for a new online retailer
Explain your approach to structuring a data warehouse to support analytics and reporting. Discuss schema design, ETL processes, and how you’d ensure data consistency and scalability.
Example answer: “I’d use a star schema for transaction analytics, with nightly ETL jobs to aggregate sales data. Partitioning tables by date would keep queries efficient and simplify maintenance.”

3.1.4 Design a scalable ETL pipeline for ingesting heterogeneous data from Skyscanner's partners
Detail how you would build an ETL pipeline to handle varying data formats and large volumes. Focus on error handling, data validation, and automation.
Example answer: “I’d set up an ingestion layer using Apache Kafka, followed by transformation jobs in Spark to normalize partner data. Automated quality checks and alerting would catch anomalies early.”

3.2. Data Engineering & Pipelines

These questions test your ability to process, clean, and aggregate large datasets efficiently. Highlight your experience with data pipelines, ETL, and data integrity solutions.

3.2.1 Design an end-to-end data pipeline to process and serve data for predicting bicycle rental volumes
Describe each stage of the pipeline, from ingestion to model serving, and discuss how you’d ensure reliability and scalability.
Example answer: “I’d automate data collection from rental stations, clean and aggregate the data in a cloud warehouse, and deploy a predictive model via an API for real-time volume forecasts.”

3.2.2 Design a data pipeline for hourly user analytics
Explain how you’d collect, aggregate, and visualize user activity data on an hourly basis.
Example answer: “I’d use scheduled ETL jobs to pull logs, aggregate metrics in a time-series database, and update dashboards every hour for actionable insights.”

3.2.3 Ensuring data quality within a complex ETL setup
Discuss strategies for monitoring and improving data quality in ETL processes, especially with diverse data sources.
Example answer: “I’d implement automated validation checks at each ETL stage and use sampling to verify accuracy. Regular audits and anomaly detection would catch systemic issues.”

3.2.4 How would you approach improving the quality of airline data?
Share your process for identifying and resolving data quality problems, including tools and frameworks you’d use.

3.3. Algorithms & Problem Solving

You’ll be asked to demonstrate your algorithmic thinking and ability to optimize for performance. Prepare to discuss time and space complexity, edge cases, and problem decomposition.

3.3.1 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.
Walk through your algorithm choice, complexity analysis, and handling of edge scenarios like unreachable nodes.
Example answer: “I’d use Dijkstra’s algorithm for non-negative costs, maintaining a priority queue for efficiency. For negative weights, Bellman-Ford would ensure correctness despite increased complexity.”

3.3.2 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.
Describe your approach to solving the problem, focusing on optimal time and space complexity.
Example answer: “I’d precompute max heights from both ends, then iterate to sum trapped water per cell. This uses two auxiliary arrays for O(n) space and a single pass for O(n) time.”

3.3.3 Create your own algorithm for the popular children's game, "Tower of Hanoi".
Explain the recursive solution and discuss how you’d generalize it for any number of disks.
Example answer: “The algorithm moves n-1 disks to an auxiliary peg, shifts the largest disk, then moves the n-1 disks onto it recursively. I’d optimize for minimal moves and stack overflows for large n.”

3.3.4 Write a function to return the names and ids for ids that we haven't scraped yet.
Discuss efficient ways to compare and filter large lists, emphasizing performance and scalability.

Example answer: “I’d build a centralized feature repository with versioning and automated updates, then connect it to SageMaker pipelines for streamlined model training and deployment.”

3.4.2 Building a model to predict if a driver on Uber will accept a ride request or not
Describe your approach to feature selection, model choice, and evaluation.
Example answer: “I’d use historical ride data to engineer features like location, time, and driver history, then train a logistic regression or gradient boosting model, optimizing for accuracy and recall.”

3.4.3 Let's say that you're designing the TikTok FYP algorithm. How would you build the recommendation engine?
Discuss the data sources, modeling techniques, and evaluation metrics you’d use to personalize recommendations.
Example answer: “I’d combine collaborative filtering with content-based models, leveraging user behavior and video metadata. I’d A/B test ranking strategies and use engagement metrics for evaluation.”

3.4.4 A logical proof sketch outlining why the k-Means algorithm is guaranteed to converge
Summarize the mathematical reasoning behind k-Means convergence, focusing on iterative optimization and objective function reduction.
Example answer: “Each iteration of k-Means reduces the total within-cluster variance, and since there are finite possible assignments, the algorithm must eventually stabilize.”

3.5. Communication & Data Visualization

Prepare to show your ability to translate technical findings into actionable insights for non-technical audiences. Focus on storytelling, visualization, and tailoring your message.

3.5.1 How to present complex data insights with clarity and adaptability tailored to a specific audience
Describe your strategy for structuring presentations and choosing visualizations that resonate with stakeholders.
Example answer: “I start by understanding the audience’s goals, then use clear visuals and concise narratives. I adapt technical depth based on the group and highlight actionable takeaways.”

3.5.2 Making data-driven insights actionable for those without technical expertise
Explain your approach to simplifying complex analyses and fostering understanding among non-technical colleagues.
Example answer: “I use analogies and focus on business impact, avoiding jargon and illustrating findings with relatable examples.”

3.5.3 Demystifying data for non-technical users through visualization and clear communication
Share methods for making data accessible, including dashboard design and interactive reports.
Example answer: “I build intuitive dashboards with clear labels and filters, and provide tooltips or guides to help users interpret the results.”
