It seems that navigating to Roblox Corporate will then redirect you incorrectly to Roblox Corporate which will then redirect you to the correct place https://careers.roblox.com/
When initially redirected to corp.roblox.com/careers you are met with a “Request Approval Form”, with most entries being set to “null”.
Expected behavior
Roblox Corporate should direct you to straight to https://careers.roblox.com/
