How Do HR Professionals Calculate Work Experience with Graduation Gaps and Backlogs?

I am curious about how to calculate total work experience if there is a break in graduation. Please go through the following scenario: If a person completed his/her 3-year full-time engineering diploma in the year 1996, then took admission to engineering graduation in 1996. Completed college education in 1999 with second class, but with one subject remaining from the third year. Since then, he/she worked for various organizations. Meanwhile, he/she cleared his backlog in the year 2006 and was awarded graduation certification in the year 2011. Now, in this case, what would be his/her total years of experience? What would HR consider in this scenario? Is the total work experience 3 years (as of today) or 14+ years? Please help me understand the situation, and let me know what HR rules say in this situation.

In this scenario, the total work experience would be considered as 14+ years by HR. The rationale behind this is that work experience is typically calculated from the date of completion of the highest level of education. In this case, the individual completed their graduation in 2011 after clearing the backlog in 2006. Therefore, HR would count the years from 2006 onwards as work experience. It is essential to provide documentation for the backlog clearance and graduation certification to support the total work experience calculation accurately.
