This morning, I just led a student to complete MathWorks Latest OA. Surprisingly, it only took 15 minutes to pass both programming questions! The whole process was very smooth and gave me the opportunity to review the question types and solution ideas for the latest OA in 2026.
If you have not done MathWorks OA, or are preparing for similar logic + implementation programming questions, this article can help you quickly understand: question style, problem-solving routines, high-frequency test points and time management skills. More importantly, you can learn from the practical experience of my students, prepare your heart and hands in advance, and make the OA process as smooth as autopilot.
OA Overall Review
The two questions in this OA are very conventional, and the difficulty level is the same as that of LeetCode Easy ~ Medium.
The system interface is simple, the input and output are smooth, and 60 minutes is enough time. Because students have practiced "logic + implementation questions" simulations with us several times before, the whole process is almost in autopilot mode, and the whole process is extremely stable.
There are no algorithm traps in MathWorks' OA. What is actually tested is coding skills and proficiency in basic questions. Rhythm and communication are more important than skills.
Q1: Valid Parentheses String
Problem:
You are given several strings containing only parentheses characters '(', ')', '{', '}', '[', ']'.
For each string, determine if it is valid — meaning all brackets are closed and ordered correctly.
Solution Idea:
Use a Stack to simulate the matching process.
- Traverse each character.
- If it's an opening bracket, push it to the stack.
- If it's a closing bracket, check whether it matches the top element of the stack.
- If it matches, pop; otherwise, return invalid immediately.
At the end, if the stack is empty, the string is valid.
This is basically the LeetCode "Valid Parentheses" template question - super straightforward, perfect warm- up. up.
Q2: Maximum Overlapping Team Size
Problem:
You are given N time intervals representing the working hours of different teams.
Find the maximum number of teams that are active (overlapping) at the same time.
Solution Idea:
Classic interval overlap problem - similar to "Meeting Rooms II."
- Extract all start and end points.
- Mark starts as
+1, ends as-1. - Sort all points by time, and accumulate the counts.
- Keep track of the maximum cumulative value - that's the maximum overlapping team size.
It can also be done via prefix counting or sweep line method; both are efficient since the input size is small.
FAQ: MathWorks OA Frequently Asked Questions
Q1: On what platform is OA done?
Official own platform, the interface is refreshing and stable, no need to install additional plug-ins.
Q2: Is there any filming or surveillance?
There is no camera monitoring, but the whole thing is recorded to detect the environment, and cutting the screen is not recommended.
Q3: Title style?
Favor basic algorithms and logic questions, the code requires simplicity and clarity, and does not test strange techniques.
Q4: Difficulty compared to other companies?
Obviously easier than financial OA (Citadel, IMC), but also simpler than Amazon OA, belongs to the "pure coding implementation" type of testing.
Programhelp Make you stand out in the OA
Logic+implementation OA like MathWorks is most likely to lose points on details (boundaries, formatting, time management). We offer a remote no-trace assist program that can help you in a limited time:
- Real-time voice alerts for input and output specifications;
- Simulated official environment preview;
- On-line seamless collaboration ensures synchronization of code rhythm and thought process;
- Comes with a review of common questions.
Many students relied on this program to get interviews with MathWorks, NVIDIA, Stripe and other companies.
If you also want to preview the OA tempo, feel free to private message us for the latest program.
