 Q6. Have you ever had any conflict with the team member (like disagreement on some design decision ) and How you reacted to it ? General2016-11-30 15:55:39

Ans. [Open Ended Answer]

This is a very sensitive question and should be dealt with caution. Just simply saying that you never had any disagreement will present you as dumb team member. Showing your self as too aggressive in such decisions will present you as a trouble maker. You should present a situation where you had an argument / disagreement but eventually you and your team mates mutually found a way out of it.
