Which of these domains TLDs do you prefer?

career.chat seems more unique and I can tell it fits your idea quite well @emekaonu

I prefer career.chat , but I have these two worries which apply to all of us, and may for years to come;

1. people are trained to use a 3-letter extension, and may be confused by a longer or shorter one
2. people will remember a *.co as *.com and when they don't see what they were supposed to won't try the *.co

I'd say avoid .co's as much as possible, they're terribly confusing.

Perhaps add a get/try-like suffix and stick to .com's instead?
