I applied through an employee referral. The process took 1 week. I interviewed at MathWorks in Aug 2013
Interview
I applied through employee referral and got an email for a technical phone interview. I didn't have an initial HR round. I was asked to submit a coding assignment prior to the interview(Java and C++). The interview lasted for almost an hour, with half of the time spend on going through the code and questions pertaining to it, which covered almost all the OOPs concepts. A few questions related to algorithms and time complexity were also asked. Previous work experience was also discussed. Almost all the questions were similar to the ones posted here.
