I spoke with the QE team manager in a 1hr 1-on-1 interview. Then, I spoke with an HR person about MathWorks for 30 minutes or so. Then I took a technical interview with a future team member on using the MATLAB test infrastructure. Finally, I gave a 30-40 minute presentation on a technical topic, and met several of the team members as well as two managers. I'd say about 8 hours total of interviewing time.

Very streamlined process, applied somewhere in the beginning of February and immediately got an OA, which consisted of 2 LC type questions (one graph based, and the other based on intervals) and Matlab MCQ questions. Later was contacted by the manager to schedule a quick 15 minute interview where she talked a bit about the company and asked BQ + some questions about resume. The last round included 3 back to back interviews over 4 hours (Technical-> Manager -> HR). Technical round involved an OOP based question and a LC styled question along with some questions about projects. The next two rounds were strictly behavioral based. The interview process was very smooth! Received a verbal offer within 3 working days followed by the formal offer. Whole process took around two months.
