who the fuck puts down "cosplay" as one of their hobbies for a job that doesn't involve some kind of sewing/costuming
come the fuck on

No sir, that's incorrect. My hobbies include reading spam email from Nigerian bankers and collecting limited edition Aluma Wallets.

Problem solving,
Creativity,
Team work,
Can travel long distances,
Can work in difficult environments,
Can get on well with strangers,
Being able to sew comes in handy when you least expect it (I've had many co-workers ask me to re-attach buttons on uniforms),
Money management,
Confidence,
Knowledge of different cultures.
There's been many times where cosplay has come up in conversations with people who I've worked for and whether they found it strange or cool at least I stay in their memory.
Interviews are about bullshitting to make yourself look good and cosplay is brilliant for bullshitting about.
I dress up as characters from kids cartoons= I am a very creative person who loves team activities and is always ready to try new things.

Considering I work in IT, any hobby that shows interaction with human beings puts you above the rest.
