Efftronics Systems Service Engineer interview questions

There will be 6 rounds except physical tests Written test, TR, IQ test, psychometric test, Physical checkup like ECG,Blood test and sugar test etc, HR, Manager. Don't waste your time to go the interview for service engineer role because we have to travel a lot on trains but the company look is good . In the physical test they took me to hospital and they asked me to run on tread mill for 12 mins. after every 3 minutes the thread mill height increasing, ECG,EEG,Sugar and BP test. I didn't understand they are taking this test for army selection are service Engineer selection and they asked me to write the bond for 3 years.
