First round is written test on which they will ask aptitude, coding and digital electronics. The coding will be mostly based on sorting and searching. The digital electronics will also be basic. The aptitude section is what I felt difficult.

So basically 1st round is aptitude + digital + programming (in return format). Atitude - logical reasoning, quantitative aptitude. (Average finding, probability) Kind of questions Digital - half adder, truth table, demultiplexer, Boolean equations, Transistor, D-flipflop. (Read everything with its application and principal) Programing - we can use any programming language to slove the problem. 1. Printing only the even numbers. N=32. 2. Finding ambiguity . 3 . Which is based on looping concept. You have to be strong in these 3 areas so then you'll be able to clear the interview. Hoping that it's helpful.
