## BSNL JTO Previous Year Question Paper

BSNL or Bharat Sanchar Nigam Limited recruits every year JTOs or junior telecom Officers, basically in three major categories, Telecom, Civil and Electrical.

Some questions we have presented here and the rest of the questions you will get from PDF which will help you to improve your understanding for upcoming exams.
