MathWorks Engineering Development Group EDG Associate interview questions

First was the group discussion round. Groups of 6-6 people were created and each group had 20 minutes to discuss on a topic. First a chance was given to each and every person and then the discussion was completely open. I passed the GD round. After that i had technical interview which started off by basic questions on cpp how to take command line args some oops question but after that went completely off the course like he asked how to host a ml model in cpp or how will i call apis in cpp. I was rejected after this interview as i wasnt able to answer the offcourse interview questions.
