Hey everyone from the amazing leetcode community, i want to get an advice.

I have been programming since 2013, started freelncing since 2014 for 4 years, and later started working with software companies. During my freelancing years i have developed websites, web apps, and services. Which gained me a lot of experience, anyway i want to apply for google and i want to know if problems difficulty are based on expeirence? or do you think its not related at all?

I'm asking because freelancing years are elastic, its possible to consider them less, because sometimes certain months work was low volume, and work often includes not only engineering, but ux, seo, data entry, and servers optimization. I obviously want to mention all of this, but if i can make questions easier, raising my chance to succed, i'm willing to say that i have freelanced for 2 years instead of 4? what do you think?

Thanks
