There was a phone screen with HR, Coding Challenge B on Hackerrank I didn't get past Hackerrank. Hackerrank has a Math Challenge which is fairly easy. There is a challenge with python or matlab and with C++,JAVA,C (whatever non scripting language you are comfortable with). If you pass this part you have an onsite with the hiring manager. Hackerank is doable if you are good at solving a lot of problems in a small amount of time. I never got a decision from the recruiter or the hiring manager. They updated my status on the online MATHWORKS jobs portal and didn't bother notifying me. They also don't respond to emails if you request update for your status. Very unprofessional.
