Hiring process is around 7-9 rounds usually. I had 7 rounds in which I got eliminated in the 4th round. It starts with a aptitude test of 15 questions, 75 minutes. All questions are technical related to physics and circuit solving. (Electric circuits, Digital & Analog Electronics, Mostly 12th std Physics like Projectile motion and also Electrostatics). They will give yoy the formulae, you should know how/when to apply it) 2nd round is programming, It consisted of 3 questions... you can solve in C only. Questions were easy to moderate. 3rd & 4th rounds are held parallely, Technical and General HR rounds. They ask about your stuff in resume, the technicality behind those. 5th is Long programming. Programming questions that are moderate-tough level. Logical solving. They test your approach to the solution
