Greetings !!

Usually competitive examinations doesn't require any previous work experience. But in some specialized vacancies like IBPS SO and certain supervisory level jobs do demand the same. If you are a fresher and a graduate you can appear for Bank , Insurance , SSC exams which actually doesn't demand any prior work experience. Stay focused in Exam preparation definitely u will be able to crack the exam. if any doubts, pls feel free to ask !

Wish you Good luck !
