if someone is placed with a certain company on campus placements and stil he has two semesters to go If he gets a KT in any of the semester does the job remains with him or not?
Did you mean arrears in any semester?
If yes, some company will allow to work, they will give you some time duration as well in which you have to clear the exams? It can vary based on companies. I have seen some companies which will allow those candidates to work as a contract employees till they clear the arrears(that to have some duration).
