Greetings !!

There won't be any issues related to the gap period. Once you cleared NET, you may be enrolled as assistant professor in college . At the time of interview , you should be able to convince your panel by giving reasonable justification for your gap. What ultimately decides is that one's own passion towards the subject. If you are passionate in teaching , definitely you will excel in it. Wish You all the Best. If any doubts, pls feel free to ask.

Thank You !!
