1st round was technical+basic aptitude+GK. 2nd round was GD. Then finally interview. Questions were asked mainly from resume in interview. Technical questions were very basic. GD too was general topics.

The interview mostly revolves around the instrumentation and it's fundamental knowledge . Alos along with what is present in your resume. Question relate to thermodynamics, working of sensors, . Previous projects done by you. Team player skills. Overall the interview are not hard but it's better for someone who has some instrumentation study background.
