Hello candidate,

There are two very basic things which we should follow in order to crack any interview, in general. The first thing is to create smart and effective impression in the eyes of the recruiter through a smart approach of answering the questions, and second is to have a good knowledge of both practical as well as theoretical matter of your subject.

Always remember that the person who is recruiting you is looking for an individual who has good management skills, and is an able communicator with his team I should have knowledge about his work.

Hope it helps!!
