MBA aspirants will be tested in GD in a month time when most of the results will be out. GD is conducted by all B schools to test your soft skills in areas of communication, body language, gestures, and focus on domain knowledge.
The assigned topic for GD will be of argumentative nature so that discussion can be done on pros and cons of issue hence, whether you are taking positive or negative side of topic it becomes immaterial but how you are presenting your thoughts is very crucial and important.
You must conclude in each and every statement as you might not get chance to revive again because of numbers of participants. This will also lead to follow ups by others and it might prove to be decider for your leadership qualities.
Practice a lot, read a lot and get success in GD!!
