Talent Screening is part of the admission phase where the selection is carried out solely on the basis of the information provided in the 'Talent Screener' tab of the application form whereas a knowledge-based interview is a structured interview that is also partly based on the information provided in the 'Talent Screener' tab, but is meant to assess your specific competencies. As your score may have varied according to your performance, a high score in the Talent Screener does not necessarily lead to a high score in the structured interview.
