Paperchase

Unlikely.

What if I’ve already gotten the interview

I didn't get my first job until I turned 16 (Minus some acting stuff I've done before), because this is the age that most employers (For part-time positions at least) look for. I've applied for various large companies and small companies alike in the past, in all sorts of fields, and most if not all of them had an age requirement of 16.

Now this isn't purely based off maturity and experience (Some of it is, I've got a few good offers because I dedicated a good few of my teenage years to volunteering in my local community, and working on bettering myself outside of school. If you haven't done stuff like this before, it's worth looking at, you'll definitely stand out to employers), a large reason that this requirement exists in companies is for various legal/insurance/safety reasons.

Paperchase, being a large multinational firm, will most likely take on people 16+. Don't feel disheartened by this, it's not a reflection of your own merit, you've done something many 14 year olds wouldn't even think of doing.
