Our occupation influences our personality traits, our presentation, our approach to life in a major way. Few instances:  One who works in business development shows more shrudeness, speak more or flatter, pamper or  pacify more. Most of the people in accounts are silent. Likewise, people in quality department always find flaws. People in police are rude or less sensitive owing to their interactions with criminals.
So, there is nothing wrong to be so.It only shows your involvement you had in that role or job.
