Round: Group Discussion
Experience: There was a healthy discussion, all 8 people of the group got enough opportunity to put forward their view. Regarding the topic, a lot many problems were discussed like intracity traffic, transportation, women empowerment, education etc. People got enough opportunity for asking cross question and also people handled cross questions maturely.
Tips: Try to think through multiple dimensions, don't restrict yourself to some specific domain. To generate points u can use SPELT method i.e. try to get points considering Social, Political, Economical, Legal and Technical aspects of an issue. Dont get aggresive give chance to others also to make their point. If you don't have your own points then also don't remain silent, try to add new dimension to the points made by other people. Be a good listener and try to summarize gd in an impressive manner.
