Say if you ran your own company, or were high up in another company, and you were holding job interviews. some guy comes in for the job and he has on his resume, that he's a black/brown belt in jujitsu?
would that make you respect the guy more, because you're aware of how much effort and dedication that takes, or would that not matter at all. I only ask because I was in a job interview the other day and the guy picks up on the fact I do bjj, he said some shit like 'isn't that the ufc thing?' so i say yes, and the guy starts asking me all these crazy questions like could i kick his ass(didn't know what to say to that). he then pretty much offered me the job, i'm guessing he was abit of a fanboy, but the point is i can see how that would've gone the other way, how he might've thought i was some thug, because he doesn't know just how much effort and discipline it takes to get a black belt(i'm not a black belt by the way)
thoughts?
If you're right out of college and don't have much else to put, it's not so bad putting such extracurricular things that demonstrate ambition, motivation, etc.
After a certain point of experience... after a few years or so... if people still have things that aren't specific to the actual industry and actual work experience on their resume, it is looked at as fluff and people see right through the attempt.
However, it also can help immensely to point out specifics about yourself for a few reasons:
1) As with your example, there is a chance that the interviewer will be into the same things as you and then you basically hit a home run.
2) Even if they aren't into it specifically, it personifies you and helps you stand out in their minds. You're not just one of a billion finance grads with a 3.0 GPA who they were forced to sit through another boring conversation with about your stupid undergrad classes... after all, they're also interviewing you to see if you're someone they wanna see 5 days a week... are you "cool" and "normal"... making yourself into a real person is better than being yet another resume.
So my advice, FWIW, is to not put anything like BJJ on your actual resume (unless you are really just out of college) but make damned sure it comes up either in the conversation, phone interview, cover letter (that many people don't read, though) or in some other casual context. Not as bragging but as an aside that you mention and hope they "take the bait" and ask about it further (which they probably will).
I liken it to flirting with girls in a bar or something. Sure, if you make a lot of money, drive a nice car, and are a BJJ black belt, it can all help you get laid... but going right up to a girl and saying it it soo obvious.. so maybe you make it look like you just happen to mention it in conversation or something rather than just walking up to the girl and saying "Hi, I'm a trader, I drive a BMW and I have a black belt in BJJ, wanna come home with me?"
