Group discussion is an important dimension of the selection process. Any institute requires students to work with others for effective functioning. Therefore, people skills are an important aspect of any MBA program.

In today's context, the educational institutes and organizations are interested in team players rather than individual contributors. During the Group Discussion, the panel essentially evaluates the candidate's potential to be a leader and also his/her ability to work in teams. Remember that institutes are typically on the look out for candidates who will inspire to lead and succeed and for that you need to be a good team player.

Here is a sample list of skills assessed during a group discussion:

Leadership skills: 
Ability to take leadership roles and ability to lead, inspire and carry the team along to help them achieve group's objectives.
Example: To be able to initiate the group discussion, or to be able to guide the group especially when the discussion begins losing relevance or try to encourage all members to participate in the discussion.

Communication skills: 
The participating candidates will be assessed in terms of clarity of thought, expression and aptness of language. One key aspect is listening. It indicates a willingness to accommodate others views. 
Example: To be able to use simple language and explain concepts clearly so that it is easily understood by all. You actually get negative marks for using esoteric jargons in an attempt to show-off your knowledge.

Interpersonal skills:
