Introduction:
The IBPS SO Exam is a competitive examination conducted by the Institute of Banking Personnel Selection (IBPS) to recruit Specialist Officers in various public sector banks. The selection process consists of multiple stages, including a preliminary exam, a mains exam, and an interview. In this response, we will discuss whether the marks obtained in each stage of the selection process are considered for the final selection in the IBPS SO Exam.

Preliminary Exam:
The preliminary exam is the first stage of the selection process. It is a screening test designed to shortlist candidates for the mains exam. The marks obtained in the preliminary exam are not considered for the final selection. However, candidates need to achieve the minimum qualifying marks set by the IBPS to be eligible for the mains exam.

Mains Exam:
The mains exam is the second stage of the selection process. It is a comprehensive test that assesses the candidate's knowledge and skills in their respective specialist field. The marks obtained in the mains exam are considered for the final selection. The mains exam consists of objective-type questions as well as descriptive questions, and the marks obtained in both sections are taken into account for the final selection.

Interview:
The interview is the final stage of the selection process. It evaluates the candidate's personality, communication skills, and suitability for the role of a Specialist Officer. The marks obtained in the interview are also considered for the final selection. The interview process may include a group discussion, personal interview, or both, depending on the bank's requirements.

Final Selection:
The final selection in the IBPS SO Exam is based on the marks obtained in the mains exam and the interview. The weightage given to each stage may vary from bank to bank. Generally, the mains exam carries a higher weightage compared to the interview. The combined marks obtained in the mains exam and the interview are used to prepare the final merit list, and candidates are selected based on their ranking in this list.

Conclusion:
In conclusion, the marks obtained in each stage of the selection process, namely the preliminary exam, mains exam, and interview, are considered for the final selection in the IBPS SO Exam. The marks obtained in the preliminary exam are used for shortlisting candidates for the mains exam, while the marks obtained in the mains exam and the interview are the key determinants of the final selection.
