This question is about the new profile page as now visible only here on Meta Stack Exchange.
In the 'Edit profile & settings' tab, you can set your Stack Overflow Careers link. I have three questions about this:
The input is called "Stack Overflow Careers link", but when you enter crap, the message says:
The Stack Overflow Careers link or username entered does not appear to be a valid Stack Overflow Careers link or username.
It's unclear to me if a username is OK as well, and what I should use as my username (my email? My id?)
Not a question, but a bug: my id as a number is accepted, but the link generated, https://careers.stackoverflow.com/260375, gives a Page Not Found.
I can't find any link that is accepted and works. These are all not accepted at the moment:
What am I supposed to enter here?
