A very smooth process. Mathworks really knows how to take care of their potential employees.

Online Round:

• 5 aptitude/maths questions.
• 2 coding questions. Leetcode medium/hard questions. Even if you solve one of the questions perfectly, you would get the telephonic screen.

Telephonic Screen: One of the hardest telephonic rounds I have had. The interviewer goes through every project on the resume and asks a lot of questions related to those projects. After that, there is an object-oriented design question. The last 20 minutes are spent coding on the HackerRank platform. You have to pass all the test cases to qualify for the next round. Mathworks expects candidates to have exceptional communication and technical skills.

On-site Interview: They take care of all the logistics properly and ensure you don't have to spend a single dollar on-site. Stay at the Marriott the day before the interview.

• 2 hours technical interview: 1 hour to explain one project in detail.
• 1 hour coding round: Very tough question and you should pass all test cases on HackerRank.
• Manager round: Behavioral questions.
• HR round: Salary/Benefits.

If you pass the tough coding round on-site, you have a good chance of getting through.
