Next, let’s dive into the specific types of questions you can expect during the Plaxonic Technologies Software Engineer interview process.

3.1. Algorithms & Data Structures

Expect questions that assess your ability to design, analyze, and optimize classic algorithms and data structures. Plaxonic Technologies values engineers who write efficient, scalable code and can articulate trade-offs between different approaches.

3.1.1 Create your own algorithm for the popular children's game, "Tower of Hanoi".
Describe the recursive solution, outline the base case, and discuss the number of moves required. Emphasize clarity in breaking down complex problems.

Example answer: “I’d use a recursive function with three parameters for source, target, and auxiliary pegs. The base case is moving a single disk directly, and for n disks, I’d recursively move n-1 disks, shift the nth disk, then move n-1 disks onto the nth.”

3.1.2 Implementing a priority queue used linked lists.
Explain how you’d organize nodes to maintain order upon insertion and removal, and discuss time complexity for each operation.

Example answer: “I’d insert each new node at the correct position by traversing the linked list, ensuring the highest priority is always at the head. Removal would be constant time, and insertion would be linear.”

3.1.3 Write a function that tests whether a string of brackets is balanced.
Discuss using a stack to track opening brackets and validate matches as you iterate through the string.

Example answer: “I’d use a stack to push opening brackets and pop when a matching closing bracket is found. If the stack is empty at the end, the string is balanced.”

3.1.4 Create a function that converts each integer in the list into its corresponding Roman numeral representation.
Show how you’d map integer values to Roman symbols and iterate from largest to smallest, subtracting values as you build the numeral.

Example answer: “I’d create a value-symbol map, loop through each integer, and repeatedly subtract the largest possible value, appending the symbol until the number reaches zero.”

3.1.5 Implementing the Fibonacci sequence using three different methods: recursively, iteratively, and using memoization.
Compare the pros and cons of each approach in terms of readability and efficiency.

Example answer: “Recursion is simple but inefficient for large n, iteration is fast and uses less memory, and memoization combines recursion with a cache for optimal performance.”

3.2. System Design & Scalability

You’ll be tested on your ability to architect scalable, maintainable systems and reason about technical trade-offs. Plaxonic Technologies values engineers who can balance performance, reliability, and extensibility.

3.2.1 System design for a digital classroom service.
Outline the main components, data flow, and how you’d ensure scalability and security. Mention potential challenges with real-time collaboration.

Example answer: “I’d design modular services for authentication, content management, and live sessions. Scalability would be supported with load balancers and cloud storage, while real-time APIs handle collaboration.”

3.2.2 Design a data warehouse for a new online retailer.
Discuss schema design, ETL pipelines, and how you’d optimize for analytical queries.

Example answer: “I’d use a star schema with fact and dimension tables, design ETL jobs for regular updates, and index for fast reporting. Partitioning and caching would improve performance.”

3.2.3 Design a scalable ETL pipeline for ingesting heterogeneous data from Skyscanner's partners.
Explain your approach to data normalization, error handling, and monitoring.

Example answer: “I’d build modular ETL stages to parse, clean, and unify data, with logging for errors and automated alerts. Schema mapping ensures consistency across sources.”

3.2.4 Aggregating and collecting unstructured data.
Describe strategies for extracting meaningful features and storing unstructured inputs efficiently.

Example answer: “I’d use NLP to extract entities, store raw data in a data lake, and process batches into structured formats for downstream analytics.”

3.3. Machine Learning & AI Concepts

Expect questions on core machine learning techniques, model optimization, and explainability. Plaxonic Technologies looks for engineers who understand both theory and practical implications of deploying ML models.

3.3.1 Implement logistic regression from scratch in code.
Describe the steps for initializing parameters, computing gradients, and iteratively updating weights.

Example answer: “I’d initialize weights, use the sigmoid function for predictions, calculate the loss, and update weights via gradient descent until convergence.”

3.3.2 Implement one-hot encoding algorithmically.
Explain how you’d transform categorical variables into binary vectors and discuss the impact on model input.

Example answer: “I’d map each category to a unique vector with one active bit, ensuring compatibility with models that require numeric input.”

3.3.3 Implement the k-means clustering algorithm in python from scratch.
Walk through initialization, assignment, and update steps, and discuss how you’d determine convergence.

Example answer: “I’d randomly select k centroids, assign points to the nearest centroid, update centroids, and repeat until assignments no longer change.”

3.3.4 How does the transformer compute self-attention and why is decoder masking necessary during training?
Articulate the mathematical process of self-attention and clarify the purpose of masking in sequence generation.

Example answer: “Self-attention calculates weighted combinations of inputs; masking prevents information leakage during training by hiding future tokens.”

3.3.5 Explain the concept of PEFT, its advantages and limitations.
Summarize how Parameter-Efficient Fine-Tuning works and when it’s preferable to full model retraining.

Example answer: “PEFT updates only select parameters, reducing resource needs and overfitting risk, but may limit model expressiveness for major domain shifts.”

3.4. Data Engineering & ETL

You’ll encounter questions about building robust data pipelines, cleaning data, and ensuring data integrity. Plaxonic Technologies expects engineers to automate, monitor, and optimize data processes.

3.4.1 Describing a real-world data cleaning and organization project.
Detail your approach to profiling, cleaning, and validating datasets, including tools used.

Example answer: “I started with exploratory analysis to identify issues, applied imputation for missing values, and validated results with summary statistics.”

3.4.2 Ensuring data quality within a complex ETL setup.
Discuss strategies for monitoring, alerting, and remediating data issues in production pipelines.

Example answer: “I implemented automated checks for completeness and consistency, logged anomalies, and set up dashboards to monitor pipeline health.”

3.4.3 Modifying a billion rows.
Describe how you’d approach large-scale updates efficiently, considering indexing and transaction safety.

Example answer: “I’d batch updates, use parallel processing, and ensure rollback support in case of errors to maintain data integrity.”

3.5 Behavioral Questions

3.5.1 Tell me about a time you used data to make a decision. What was the outcome and how did you communicate your findings?

3.5.2 Describe a challenging data project and how you handled it. What technical and interpersonal hurdles did you overcome?

3.5.3 How do you handle unclear requirements or ambiguity when starting a new project?

3.5.4 Tell me about a time when your colleagues didn’t agree with your approach. How did you bring them into the conversation and address their concerns?

3.5.5 Talk about a time when you had trouble communicating with stakeholders. How did you overcome it?

3.5.6 Describe a time you had to negotiate scope creep when multiple teams kept adding last-minute requests. How did you keep the project on track?

3.5.7 When leadership demanded a quicker deadline than you felt was realistic, what steps did you take to reset expectations while still showing progress?

3.5.8 Give an example of how you balanced short-term wins with long-term data integrity when pressured to ship a dashboard quickly.

3.5.9 Tell me about a situation where you had to influence stakeholders without formal authority to adopt a data-driven recommendation.

3.5.10 Describe how you prioritized backlog items when multiple executives marked their requests as “high priority.”
