The Technical Graduate Course, popularly known as TGC, is one of the most prestigious officer entries into the Indian Army for engineering graduates. Every year, thousands of technically qualified candidates apply for this entry, hoping to combine their engineering expertise with the honor of serving as Army officers.
However, many TGC aspirants make one common mistake. They focus entirely on technical subjects and engineering concepts while overlooking the fact that the SSB Interview is not selecting engineers—it is selecting future leaders of soldiers. Technical knowledge is important, but Officer Like Qualities, leadership potential, responsibility, communication skills, and personality play a much greater role in the recommendation process.
