Important PSA: we've received reports of scammers who are posing as Manticore recruiters using a fraudulent email address. Legit emails from Manticore will always come from a address - note the plural 'games', not singular.
For real roles at Manticore, we'll communicate by official email. We don't use gmail addresses, and we don't ask candidates to switch to a messaging app like Telegram. We do always do video interviews, so you'll see us on camera.
As this is becoming more common in the game industry, we recommend all job hunters carefully note the "from" email of recruiters. Never share your banking information or make a purchase of equipment based on a social media message. If in doubt, reach out to others at the company.
