I don't think I've ever had the luxury of being able to work on one assignment at a time.
I don't even know if there is any position out there with that luxury.
In my last job,I had deadline after deadline.
Sometimes I had three deadlines falling on the same day.
Working on multiple assignments at once comes natural to me.
I never consciously thought,“Oh,gee,what am I going to do with all these assignments?”
I have been told I work very effciently.
