Ability to work in deadline mean you have ability to handle stress and also manage time. How many of you agree with this?

I do

Definitely, as this is a clear indication of time and stress management in one situation. 

This is because, you have to ensure that you are organised and orderly, without which you cannot meet deadlines, thereby affecting the time taken to handle the job and ultimately stresses you out if it is not carried out within the time limit.

So if the person is efficient, he will have this ability automatically.
