If I were a hiring manager, I would be impressed
I’m not going to lie, I would put it on mine. I don’t know why there’s so much hate for you asking. I think it’s an impressive skill. But what do I know?
For what it’s worth, I would be impressed if you could successfully count cards
At the same time, 4 out of 5 people who try to count cards fail at it anyways so they still end up losing to the casino.
It’s not advisable to be making up stuff on a resume just to look cool and stand out. I’d just go with full disclosure and admit to relying on a cheat sheet when playing texas holdem with friends.
Honestly counting cards isn’t that impressive… if you can memorize basic strategy and learn to keep a running plus-one / minus-one count going in your head it’s not that hard with some practice. The hardest part is translating from mastery on the computer to mastery in the casino (making conversation, appearing relaxed and not too focused on the cards).
I’ve made some money at card-counting – although I’ve never been banned from a casino. Regardless, it would be totally amateurish to include it on your resume.
I personally have an angle with sportsbooks that I’ve used to steadily supplement my income (I’ve also been banned / limited at multiple sportsbooks) – but it goes without saying that I would never include it on my resume of professional accomplishments.
Definitely don’t write that you have been banned from casinos. I’m neutral on including poker on the resume- some roles might appreciate the applied use of probability (trading/strats/pricing), while others probably won’t.
When I was an undergrad applying for jobs I listed my poker winnings # (reasonably impressive). Not sure if I mention on there that I started with $60.
My first boss after college kept on calling me phil ivey as a joke from time to time. Guess it helped.
