Dear Maneesha,

As of i can see you want to know about interview skills of commerce teacher recruitment.

First of all, I would recommend you to believe in yourself. Be confident. Sharpen your skills as well.

Dress in formals appropriately. Be polite to interviewers, even teachers are supposed to be polite itself.

Moreover, there are many videos in youtube where you will get to see real interview happening. You can visit them to improvise yourself.

Hope this helps.

All the Best!!
