There is a regular fix question according to your experience.
If you are fresher then interview for you will be from engineering syllabus.
And if you are a veteran, then question will regarding your experience, your present or current company product details, manufacturing process, your achievments etc. But, the common questions are as below.
- Tell me about yourself.
Which include, your education, your experience, your native place.
2.Tell me about your family background .
- Tell me about your strength and weaknesses .
Because of not prepare, lots of candidate jumbling on this question.
- If you are fresher then for you,
Why you want to join our organisation.
- And, if you are veteran, then for you,
-Why you want to leave or left your job, and why you want to join our organisation. -How you can contribute, to our organisation. - What is your current job profile.
All above questions are compulsory, and must prepare it all.
Dont allow interviewer to talk more, you extent your communication.
But, in your communication, dont include or mention such thing, about which you dont have knowledge.
Best Luck!
