How do you priorities your work? (this question is asked in most of the job interview)

The best way for myself to prioritise my work is by looking at the objectives of the day and realising what is the most urgent and important.  These jobs can be done first.  Sometimes other more important jobs come in, where you may need to evaluate your tasks. Making sure your time manage also is a must. 

You can prioritise you work, by allocating task on basis of importance and urgency. You can mention time management techniques. 

try to be ahead of your work......... dont limit yourself to your job

What is the most important tasks that would significantly affect and influence business, Both Positively and negatively, however for me I prefer to end tasks as soon as i catch them. 

so this way I finish all in the appropriate time, and before even deadline got close. 

Meaning, you have to do what you have to do, so do it now.
