# Invincio Services LLP > India's premier SSB interview mentorship institute, run exclusively by Ex-SSB Assessors (GTOs, Interviewing Officers and Psychologists) who have personally evaluated thousands of candidates at Services Selection Boards. Invincio is a Leadership Transformation Institute focused on personality evolution rather than rote memorisation.
