This is a common question, though few people answer it adequately. I don't believe denying weakness is ever the right response. I honestly stated the one thing I had to continuously be aware of and work on was my demeanor when assigning work/tasks. I could sometimes come across as demanding or over-bearing, although it was never my intention. The direct and blunt approach can often come off as abrasive and it's something I worked hard at improving each day.
