It's urgent please check out grammatical my errors.

Actually I am to going for giving interview in coaching institute. So If they had asked me that question I would have reply as such a way as I given here. Whether this reply is correct or not.

Q.1- Why are you taken two years gap after completing Engineering degree?

Sir, During my engineering degree, I did not apply for any company because I want to become a tutor of competitive exams. Even my college offered me a job as a Assistant professor but I denied them. Actually, during my placement Arvind Sharma who is came from "ILLUMINATE MINDS" company in my college and he asked students " Any one interested in aptitude tutor job." I replied him "Yes sir I am interested." and then he told me okay you will clear each and every topic then I will call you. but due to some serious family issue I had not prepared for a very long time. Even Arvind sir called me but I denied him because I was not prepared. So I started preparing reasoning and Quantative Aptitude and I am searching opportunity and I have seen this opportunity in your organisation.
