  • General: 40%

  • BC: 36.5%

  • EBC: 34%

  • SC/ST, Women and PwD: 32%

Stage 3: Bihar APO Interview

Candidates who qualify in the Main Examination will be shortlisted for the Bihar APO Interview.

The Interview carries 100 marks.

Candidates must meet the prescribed minimum qualifying marks in the relevant written papers, excluding Hindi and English, to become eligible for the Interview.

BPSC will call candidates for the Interview based on their Main Examination performance. As per the notification, candidates up to 2.5 times the number of advertised vacancies will be called for the Interview.

Appearing in the Interview is mandatory for candidates who qualify for it. A candidate who does not appear for the Interview will not be included in the final merit list.

Bihar APO Final Selection

The final selection is based on the candidate's performance in the Main Examination and Interview.

The Preliminary Examination marks are not included in the final merit calculation.

The selection process can be understood as:

Prelims → Mains → Interview → Final Merit List

The final merit list will be prepared by combining the marks obtained in the Main Examination and Interview.

If two or more candidates secure equal total marks, the candidate with higher marks in the Main Examination will be placed higher in the merit order. If the Main Examination marks are also equal, the prescribed alphabetical order based on the candidate's name in Devanagari script will be used.

The Bihar APO Selection Process 2026 is conducted in three stages: Prelims, Mains, and Interview. Since Prelims is only a screening stage, candidates should focus strongly on the Mains Examination, as its marks are considered for the final merit list along with the Interview. Candidates should understand the exam pattern, qualifying requirements, and shortlisting criteria at each stage to prepare effectively and improve their chances of final selection.
