first round is mcq + coding round the mcq is based on microprocessors. After clearing that you will have 2-3 technical rounds. You must use C launguage and all rounds are online for me.

Initially, they conduct an online exam based on core embeeded systems and c programming language. Then, they shortlist students for an 1st round interview. At this first round of interview, they more concentrate on C language questions and coding. They will shortlist the students for further rounds(interviews).
