Overall, a very positive interview process with MathWorks. Stephen might be the best and most responsive hiring manager I have ever met. The entire interview lasted one month. I had the 1st round interview with the hiring manager through a virtual meeting to talk about my past work. And then I had a followed up phone call with HR to discuss salary and other stuff. The next round was talking to another UX manager at a different team. After that, they gave me a week to complete a take-home UX design challenge(I also prepared a deck to present the process and solution). For the final onsite, I did a 30-40mins portfolio presentation and had five 1-1 sessions to talk to different teams. Mathworks did background check and reference check before informing the final offer. They have a very restrictive salary policy; if you don't reach senior level, then you might receive the same salary as people with fewer years of working experience. And they are not very willing to negotiate salary. In the end, I got a much better offer from a different company so I rejected the offer from Mathworks.
