Updated June 10, 2019

When appearing in an interview that tests your technical strengths, you may feel a bit uneasy even if you know all that you are supposed to.

Technical interviews are overwhelming because many questions may be asked that you have only book knowledge of; and since most of us do not remember what we read in course books during college, we can feel a little intimidated.

 

One does not have to feel intimidated though. If you have earned a college degree in a particular discipline and are preparing yourself for an interview, research what questions you may be asked and read up on them.

Since you have already grasped the concepts in college, reading them once more will help you recall them, and you will be prepared for the toughest of questions.

To make this more understandable, let us take the example of a GIS technician preparing for an interview.

GIS is a complicated field, and an interview for a GIS Technician position means many technical questions thrown your way. Let us see what questions (and their answers) you might be asked during an interview for this position.
