1. 5 question video interview with same questions mentioned by most of the people in glassdoor 2. Technical phone interview questions The interviewer asked me questions related to Embedded systems and OS related, Most of the questions related scheduling, Preemption, priority inversion, real time OS etc. I answered all of them really well with examples. Then the interviewer asked me questions on C programming related to static variables, array bound checking ,pointers. The unexpected part was related to math. The recruiter said that there will be math related questions on calculus, Linear algebra etc. But interviewer asked me questions on probability, Arithmetic progression etc. I answered questions related to probability but i forget formulas related to AP. I remembered after interview. That's was annoying for me. Matlab questions were easy on plots, title, legend .
