I applied through an employee referral. I interviewed at Promac Engineering Industries (Bengaluru) in Aug 2015
Interview
went smooth, long waiting process, have patience and learn to greet senior engineers.
all other skills are same as the normal interview process and keep record of your academics, the last stage distinguishes you same like the tata, and isro process.
Interview questions [2]
Question 1
normal, know your maths and mechanical engineering (mostly defects, welding, stress relieving, NDT, etc...)
