E-sports competitor

E-sports competitor is technically not a career but an Afterschool activity like the Scout (career) featured in The Sims 4: Seasons

As with any career, your Sim can join the E-Sports Competitor career by sitting down at a laptop, computer, using their cell phone or by the career tab on the user interface. You will then be given the option to choose which of the two new careers you would like your Sim to join. You can also click on the Foxbury Arena and click the button that says Join a Sports Team

If you get the highest level (check here for the level Career tracks) you can become a level 5 Tech guru in e-sports.
