Now, let’s dive into the specific interview questions you can expect throughout the process.

3.1. Algorithms & Data Structures

Expect questions that evaluate your grasp of algorithmic fundamentals and data structure design, especially in the context of scalable healthcare and data-intensive applications. VideaHealth values engineers who can design robust solutions for real-world problems, so be prepared to discuss both implementation and optimization.

3.1.1 Given an array of integers, write a function to calculate the minimum absolute distance between two elements then return all pairs having that absolute difference.
Start by sorting the array or using a hashmap to efficiently track pairs and distances. Emphasize clarity in edge cases such as duplicate values and negative numbers.

Example answer: "I would first sort the array to easily compare adjacent values, then iterate to find the minimum difference and collect all pairs matching that difference."

3.1.2 Search for a value in log(n) over a sorted array that has been shifted.
Explain how to adapt binary search to handle the shift, identifying the pivot point and narrowing your search accordingly.

Example answer: "I would use a modified binary search to locate the pivot, then determine which subarray to search for the target value, maintaining O(log n) complexity."

3.1.3 Given the root node, verify if a binary search tree is valid or not.
Discuss recursive or iterative approaches, ensuring that each node satisfies BST properties within proper value bounds.

Example answer: "I’d use recursion to check that every node falls within the valid min/max range as I traverse the tree, confirming BST validity."

3.1.4 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.
Describe your choice of algorithm for the graph type and how you would optimize for performance and memory.

Example answer: "For non-negative weights, I’d use Dijkstra’s algorithm with a priority queue, ensuring efficient updates and path reconstruction."

3.1.5 Implementing a priority queue used linked lists.
Outline how to structure the linked list and manage insertions and removals while maintaining priority order.

Example answer: "I’d insert elements in sorted order so that removals are always from the head, and use traversal for insertions to keep the queue efficient."

3.2. System Design & Data Engineering

These questions assess your ability to design scalable data pipelines and systems suitable for healthcare data, including ingestion, transformation, and storage. VideaHealth looks for engineers who can balance robustness, maintainability, and performance.

3.2.1 Design a robust, scalable pipeline for uploading, parsing, storing, and reporting on customer CSV data.
Discuss modular pipeline stages, error handling, and monitoring, with a focus on scalability and data consistency.

Example answer: "I’d use a multi-stage ETL pipeline with validation, schema enforcement, and parallel processing, storing results in a normalized database."

3.2.2 Aggregating and collecting unstructured data.
Describe your approach to extracting structure from raw data, leveraging tools for parsing and enrichment.

Example answer: "I’d use data parsing libraries and NLP techniques to extract entities, then store structured results for downstream analytics."

3.2.3 Design a scalable ETL pipeline for ingesting heterogeneous data from Skyscanner's partners.
Highlight schema mapping, error resilience, and how you’d handle evolving data formats.

Example answer: "I’d build modular connectors and schema transformers for each partner, with automated validation and fallback mechanisms."

3.2.4 Let's say that you're in charge of getting payment data into your internal data warehouse.
Focus on data integrity, latency, and auditability, especially for sensitive financial data.

Example answer: "I’d implement incremental loads with transaction logs, strict validation, and encryption for secure storage."

3.2.5 How would you design database indexing for efficient metadata queries when storing large Blobs?
Discuss trade-offs between index types, metadata schemas, and query performance.

Example answer: "I’d use composite indexes on frequently queried metadata fields and partition large tables to optimize access speed."

3.3. Machine Learning & Modeling

VideaHealth expects software engineers to understand core ML concepts, particularly those relevant to healthcare applications. Questions will probe your reasoning about model selection, evaluation, and deployment.

3.3.1 A logical proof sketch outlining why the k-Means algorithm is guaranteed to converge
Summarize the iterative nature of k-Means and how the objective function ensures convergence.

Example answer: "Each iteration reduces the total within-cluster variance, and since there are a finite number of partitions, the process must converge."

3.3.2 Creating a machine learning model for evaluating a patient's health
Describe your approach to feature selection, model choice, and validation for healthcare risk.

Example answer: "I’d select clinically relevant features, use logistic regression or tree-based models, and validate with cross-validation and ROC analysis."

3.3.3 Let's say that you're designing the TikTok FYP algorithm. How would you build the recommendation engine?
Explain your approach to collaborative filtering, feature engineering, and handling cold start problems.

Example answer: "I’d combine user interaction histories with content features, using matrix factorization and deep learning for personalized recommendations."

3.3.4 How does the transformer compute self-attention and why is decoder masking necessary during training?
Describe the mathematical basis for self-attention and the role of masking in sequence models.

Example answer: "Self-attention computes weighted averages of input tokens; masking prevents the decoder from seeing future tokens during training."

3.3.5 Delivering an exceptional customer experience by focusing on key customer-centric parameters
Discuss which metrics matter most and how you would model and improve user experience.

Example answer: "I’d track delivery times, ratings, and repeat usage, using regression models to identify improvement opportunities."

3.4. Product & Feature Analysis

These questions evaluate your ability to analyze, improve, and communicate about software features—critical for healthcare platforms where usability and reliability are paramount.

3.4.1 What kind of analysis would you conduct to recommend changes to the UI?
Discuss user journey mapping, funnel analysis, and how you’d use data to prioritize UI improvements.

Example answer: "I’d analyze drop-off points in user flows, conduct A/B tests, and gather qualitative feedback to guide UI changes."

3.4.2 Let's say that we want to improve the "search" feature on the Facebook app.
Explain how you’d analyze current search performance and propose data-driven enhancements.

Example answer: "I’d review search logs, identify common failure cases, and test new ranking algorithms to boost relevance."

3.4.3 How would you analyze how the feature is performing?
Describe key metrics, cohort analysis, and experimentation to assess feature impact.

Example answer: "I’d track conversion rates, segment users by engagement, and run controlled experiments to measure improvements."

3.4.4 Designing a dynamic sales dashboard to track McDonald's branch performance in real-time
Focus on real-time data aggregation, visualization choices, and alerting for key metrics.

Example answer: "I’d use streaming data pipelines and interactive dashboards to surface performance trends and actionable insights."

3.4.5 How to present complex data insights with clarity and adaptability tailored to a specific audience
Discuss tailoring your message, using visualizations, and adapting for technical versus non-technical stakeholders.

Example answer: "I’d use clear visuals, focus on actionable findings, and adjust my explanations based on the audience’s familiarity with data."
