This section was the litmus test.

Most of the questions asked were from :-MOM, TOM, DME, THERMODYNAMICS, CAD/CAM & F. M.

The best strategy to go about this round is to attempt what you know and flag questions you are uncertain of. Remember there is a 0. 25 negative marking.

Technical Interview Questions:

In this round you will be tested for your basic knowledge relating to mechanical engineering.

It starts with introduction. Do remember to mention your favourite subject (Most of the questions quizzed on). Next he asked me about my minor project which was based on design. He quizzed me on GD&T, Angle of projection, My role in the project & Scope for improvement.


1) Build your resume/CV it adds worth to your skills and gives a message that you are ready to work at the industry level.
2) Everyone gets nervous.  (Just don't show it).
3) Above all prepare well by referring websites like indiabix.com and some others just to know where you stand.

HR Questions:

This in my opinion was the easiest round.

1) Introduce yourself.
2) Family Background.
3) Strengths & Weakness.
4) What do you know about BOSCH?
