Civil Engineering Interview Questions

Hello Friends,

Are you appearing for an interview for the first time as a fresher for civil engineering job? First of all you are lucky if you get a chance to attend an interview. Basically most of the companies ask this question ‘Who Sent You?’. Reference plays an very important role in our civil engineering industry.

Here i am going to share Top Entry Level Engineering Interview Questions and their Answers. Thus questions will help you a lot in Interview. Fresher students can increase their theoretical knowledge.Generally in interview for Fresher students or candidates asking the basic knowledge about related to Civil Engineering field and also common questions relate to civil engineering.

If the applicant is giving Civil Engineering Technical Interview For Civil Site Engineer for the first time then the interviewer take interview from the Introduction to the Basics of the civil engineering.
