Example scenarios:

• "Walk me through your solution to the second coding question from your online assessment. What was the bottleneck, and how would you rewrite this to improve spatial efficiency?"
• "Given a stream of incoming simulation data points, write a function to dynamically find the largest elements using a heap structure."

Low-Level & Object-Oriented Design (LLD/OOD)

You will be asked to design and implement software systems that demonstrate a mastery of object-oriented principles. The interviewers want to see that you can write clean, compilable, and highly structured code on the spot.

Be ready to go over:

• Encapsulation & Inheritance – Designing clean class hierarchies while avoiding common pitfalls like the diamond problem in C++.
• Design Patterns – Utilizing standard patterns (e.g., Singleton, Factory, Observer) where appropriate to solve architectural challenges.
• Interface Design – Creating clear, decoupled interfaces that make software systems easy to test and extend.

Advanced concepts (less common):

• Custom memory allocators in C++
• Thread safety in multi-threaded object designs
• Operator overloading and template metaprogramming

Example scenarios:

• "Design a low-level simulation of an automated coffee machine. Write the class definitions and implement the core state transition logic using OOP principles."
• "Implement a movie-ticket booking system. Show how you handle concurrent seat selection and define the relationships between users, theaters, and shows."

Core CS Fundamentals & Language Semantics

MathWorks relies heavily on low-level language performance and robust system architectures. You must show an in-depth understanding of how your chosen programming language interacts with the underlying operating system and hardware.

Be ready to go over:

• Memory Management – Pointers, references, stack vs. heap allocation, and smart pointers (e.g., std::unique_ptr, std::shared_ptr in C++).
• Operating System Basics – Processes vs. threads, concurrency, deadlocks, and memory-mapped files.
• Database and Networking – Basic relational database concepts, indexing, and networking protocols if relevant to the role.

Example scenarios:

• "Explain the difference between a shallow copy and a deep copy. Write a class in C++ that safely implements a deep copy constructor."
• "What happens under the hood when a virtual function is called in C++? Explain the mechanics of the vtable and vptr."
