How many stripes does a student pilot have?
Stripes don't have any standardized meaning in between companies. If a company wanted, it could give one stripe to its most senior captains and four stripes to the office dog.

If your employer or your school has issued you a uniform, then the number of stripes that you have is the number of stripes that they decided to put on that uniform. If you haven't been issued a uniform, then you don't have any stripes.
