Applied and received a Hirevue at first with 4 standard behavioral questions. Afterwards received a Hackerrank Coding challenge. Challenge was divided into 3 parts. First part was math questions, (15 minutes) 5 of them in MCQ format with topics ranging from basic calc to discrete math. Second part was coding challenge 2 questions (45 minutes total) of medium difficulty. Final part was (30 minutes) 10 questions related to Matlab (ie syntax, output, plotting) in MCQ format. Important to note that final (Matlab) section was optional but definitely recommended. Despite passing all test cases in coding challenge didn't proceed to live interview. Overall wouldn't recommend.
Interview questions [3]
Question 1
Coding question: Convert Binary to decimal where binary is given as a linked list?
I applied online. The process took 3 weeks. I interviewed at MathWorks (Natick, MA) in Oct 2017
Interview
Initial HR phone screen (brief), partially informative, partially behavioral interview. Online Coding Challenge, with plenty of flexibility. Follow-up phone interview with a Software Engineer.
All steps above were completed within 2 weeks. I was called about a week later by the HR representative but was not available at the time, and was unable to get in contact with HR again. After a while, I checked the Mathworks careers website and found my application status had been updated to "Match not ideal at this time." I assumed that was a 'no.'
Interview questions [3]
Question 1
The HR phone screen was informative, more about me learning about the company and the job than about testing my personality/work ethic. Some behavioral/resume questions.
The Coding Challenge was 1 hour in length at a time of my choosing within a week from the HR phone call. I was expected to complete 2 challenges, and was given a choice between two different challenges for each (given four challenges, do 1 or 2 AND 3 or 4). I was allowed to use C++ or Java, provided that I use both (one for each problem).
The follow-up phone interview was 45 minutes in length, and began with a review of my code from the challenges. I was asked to run through how I came about my answer and how it works, then asked about its efficiency. An extension question was asked for each (how would I change my code to account for this new stipulation?). Then I was asked a handful of unrelated programming questions, most of which involved writing code (e.g. design an inheritance hierarchy to represent this real-life situation).
