Truthfully fill in the number of years you actually participated in the work. This number of years refers to the number of years I have worked since I joined the work. For example, if you have worked for 6 years, then fill in 6.
Your new employment time is less than half a year, so when applying for a credit card, your work experience can be appropriately extended to more than half a year. Please note, however, that banks should keep the consistency of information when they pay a return visit. Because more than half a year is the minimum threshold for banks to review applicants' working years.
