IBPS strength is its research based capability to design multiple choice objective tests and tools for testing of candidates appearing for the post of clerks, probationary officers and SO (Specialist Officers) in banks across India. The IBPS clerk exam is universally adapted by nationalized banks across India to induct fresh graduates into various clerical posts. This exam comprises five sections covering Reasoning, English, Numerical Ability, General Awareness and Computer knowledge. Applicants first appear for a preliminary exam covering English, Numerical Ability and Reasoning. Only those candidates satisfying the cut off point for each section are eligible to appear for the final CWE. IBPS also conducts exams for recruitment to the post of probationary officer (PO) and specialist officer (SO). The exam pattern is similar to that conducted for recruiting clerks but with higher difficulty level for PO posts. The post of Specialist Officers covers agriculture field officer, rajbhasha adhikari, IT officer, law officer, technical officer, HR/Personnel officer and marketing officer as well as finance executives and chartered accountants.
