I found it went to careers.microsoft.com from the link in internal hrweb
You can see hiring manager and level if you sign in with your microsoft credentials (there is an employee sign in button). That said, the search sucks. By default they search by relevance so you see months old posts at the top. For me, i want to search by role, level and city and sort by newest. I also want to save the search criteria so that i dont have to select all the criteria every time i gets signed out. And you get auto signed out really quickly, not sure why they cant keep you signed in for at least a week.
