The first round was telephonic interview which lasted for 45-50 minutes.Questions were a mix of behavioral and technical.After a week I was informed that I have cleared the 1st round and had to attend a telephonic technical interview.The interview was conducted a week later.I was asked basic questions from Math(Linear algebra),DSP,C and Matlab.The interview lasted for about an hour.The next day I was informed of the results,I had to attend the next round which is F-F at the Mathworks office. The first round which lasted for an hour was on puzzles and basic C programming.The second round was an advanced version of the 2nd telephonic interview.This one was a bit tough.Next was the lunch session where I got to meet the team members and had the chance to clarify all my doubts regarding the job.The next one was behavioral interview with the Manager.This round was followed by the video conferencing round with onsite Manager.Finally came the HR round. People were very friendly.I never felt stressed out at any point.The site interview started at around 10 AM and lasted till 5:30 PM.
