Technical Questions depends on what that particular company is about. Ex. If it’s bridge construction company they’ll ask you about structural part, pre stress concreting etc. Questions can be raised from your seminar, training & project topics during B.Tech/M.Tech. and Main projects going on nearby your area.

General questions are based on about yourself, about hobbies. You should be well acquainted with the place you belong from, company you worked in past n also the one you are joining.

Will update Later. Good Luck.
