Next, let’s dive into the specific interview questions commonly asked throughout the Acumen Software Engineer process.

Below are sample interview questions you may encounter for the Software Engineer role at Acumen. These questions target the technical and business acumen competencies required at Acumen, with a strong emphasis on algorithms, data handling, system design, and clear communication of insights. Focus on demonstrating practical engineering problem-solving, the ability to design scalable systems, and your understanding of how software solutions drive business outcomes.

3.1 Algorithms & Data Structures

Expect questions that assess your understanding of core algorithms, data structures, and their application to real-world problems. Acumen values efficient solutions and clarity in reasoning, so be prepared to discuss trade-offs and edge cases.

3.1.1 Implementing a priority queue used linked lists.
Explain how you would structure nodes, maintain order during insertions, and efficiently handle removals. Discuss time and space complexity and potential optimizations.

Example answer: "I’d implement the queue with a linked list where each node contains a value and a priority. Insertions traverse the list to maintain sorted order, and removals always take the highest-priority node from the head. This approach is simple but can be optimized with a doubly linked list for faster removals."

3.1.2 Detect a cycle in a singly linked list.
Describe the algorithm (e.g., Floyd’s Tortoise and Hare), why it works, and how you’d handle edge cases like empty or single-node lists.

Example answer: "I’d use two pointers moving at different speeds; if they ever meet, a cycle exists. This method is efficient, requiring no extra space and handling all list sizes."

3.1.3 Create a binary tree from a sorted list.
Discuss how to recursively split the list to ensure the tree is balanced, and explain the benefits of this structure for search operations.

Example answer: "I’d recursively select the middle element as the root, then repeat for left and right sublists. This guarantees a balanced tree for optimal search performance."

3.1.4 Designing a dynamic sales dashboard to track McDonald's branch performance in real-time
Explain how you’d structure the backend, efficiently update rankings, and handle high-frequency data streams.

Example answer: "I’d use a distributed cache for real-time updates and a priority queue to maintain branch rankings, with periodic batch processing for historical trends."

3.2 System Design & Data Engineering

These questions evaluate your ability to architect scalable systems, design robust data pipelines, and ensure data integrity within complex environments. Acumen seeks engineers who can translate business requirements into resilient technical solutions.

3.2.1 System design for a digital classroom service.
Describe your approach to user management, real-time collaboration, and scalability. Address potential bottlenecks and security concerns.

Example answer: "I’d use microservices for modularity, WebSocket for real-time updates, and cloud storage for scalability. Security would be managed via role-based access controls."

3.2.2 Design a scalable ETL pipeline for ingesting heterogeneous data from Skyscanner's partners.
Outline how you’d handle schema variability, ensure data quality, and automate error handling.

Example answer: "I’d use a schema registry for validation, implement automated anomaly detection, and design modular ETL stages to handle different partner formats."

3.2.3 Aggregating and collecting unstructured data.
Discuss strategies for parsing, storing, and retrieving unstructured data efficiently.

Example answer: "I’d use a NoSQL database for flexible storage, implement text parsing with regular expressions, and batch process data for downstream analytics."

3.2.4 Design an end-to-end data pipeline to process and serve data for predicting bicycle rental volumes.
Explain how you’d architect ingestion, transformation, and predictive modeling components.

Example answer: "I’d set up streaming ingestion, use Spark for feature engineering, and deploy models with a REST API for real-time predictions."

3.2.5 Design a data warehouse for a new online retailer
Describe schema design, partitioning strategy, and how you’d optimize for query performance and reporting.

Example answer: "I’d use a star schema for analytics, partition tables by date, and index key columns for fast reporting."

3.3 Data Quality, Cleaning & Business Acumen

Acumen expects engineers to ensure high data quality and understand the business impact of their work. Questions in this section target your experience with messy data, ETL processes, and communicating technical decisions to non-technical stakeholders.

3.3.1 Ensuring data quality within a complex ETL setup
Explain your approach to monitoring, validation, and remediation of data issues across multiple sources.

Example answer: "I’d implement automated data validation checks, use anomaly detection for key metrics, and maintain detailed logs for auditability."

3.3.2 Describing a real-world data cleaning and organization project
Share how you diagnosed issues, chose cleaning methods, and balanced speed with accuracy.

Example answer: "I started with profiling, applied imputation for missing values, and documented each transformation to ensure reproducibility."

3.3.3 How would you answer when an Interviewer asks why you applied to their company?
Focus on aligning your skills and interests with Acumen’s mission and business challenges.

Example answer: "I’m excited by Acumen’s focus on data-driven decision making and believe my experience in scalable systems will help deliver impactful solutions."

3.3.4 How to present complex data insights with clarity and adaptability tailored to a specific audience
Discuss strategies for simplifying technical findings and tailoring presentations to stakeholder needs.

Example answer: "I use visualizations and analogies, tailor depth to audience expertise, and always link insights to business outcomes."

3.3.5 Making data-driven insights actionable for those without technical expertise
Describe methods for bridging the gap between technical analysis and actionable business recommendations.

Example answer: "I translate findings into business terms, use clear visuals, and provide concrete next steps."

3.3.6 Demystifying data for non-technical users through visualization and clear communication
Explain how you enable self-service analytics and foster data literacy.

Example answer: "I build interactive dashboards, offer training sessions, and document key metrics in plain language."

3.4 Probability, Statistics & Experimentation

Acumen values engineers who can apply statistical reasoning to business problems, design experiments, and interpret results for actionable insights.

3.4.1 The role of A/B testing in measuring the success rate of an analytics experiment
Discuss experimental design, key metrics, and how to ensure validity.

3.4.2 What is the difference between the Z and t tests?
Clarify when to use each test, assumptions, and implications for business decisions.

Example answer: "Z-tests require known variance and large samples; t-tests are for smaller samples or unknown variance. Choosing correctly ensures reliable results."

3.4.3 How would you establish causal inference to measure the effect of curated playlists on engagement without A/B?
Describe quasi-experimental methods like propensity matching and regression analysis.

Example answer: "I’d use propensity score matching to control for confounders and regression to estimate impact, ensuring robust causal claims."

3.4.4 Delivering an exceptional customer experience by focusing on key customer-centric parameters
Explain how you’d identify, measure, and optimize relevant metrics.

Example answer: "I’d track NPS, delivery times, and order accuracy, then analyze drivers of satisfaction to prioritize improvements."
