Hello Vikash,
Even if you don’t have work experience you can apply for IIFT. It is not mentioned anywhere that it is compulsory to have work experience. However, I feel they might question you regarding the gap between your graduation (which took place in 2016 I assume). What did you do in these two years? You can apply, but in the interview round you might be asked this question.

Kindly contact me if you have confusion about this.

I hope this was helpful and all the best!
