The banking sector selection process is generally long and complicated compared to the telecom sector. It involves preliminary interviews, application screening, employment tests assessing intelligence, aptitude, personality and proficiency, and comprehensive interviews. The telecom sector process is less formal and involves preliminary interviews, application forms, aptitude and reasoning tests, personality tests, technical and comprehensive interviews, background and security checks, and medical examinations. Both sectors require different skills, with banking focusing on financial background and analytical abilities, while telecom emphasizes technical knowledge of the telecommunications industry.
