Latest BSNL TTA Updates

Last updated on Mar 30, 2023

BSNL holds a BSNL TTA Exam to recruit candidates for Telecom Technical Assistant (TTA) post. For the last recruitment cycle of BSNL TTA, a total number of 2700 vacancies were released. It is expected that the BSNL (Bharat Sanchar Nigam Limited) will release the same or more than the previous year's vacancies. The selection of the candidates for TTA will depend on Online Examination and Document Verification. Candidates can refer to the BSNL TTA previous years' papers to increase their chances of selection for this post.
