I have tried to create my profile on Careers, but being an invitation-based system and having no one around I could get invitation from, I tried my luck posting my address at the details pane - the one which says
No doubt! You can request an invitation by entering your email address below, and we will review it.
How long does this review process take and will I even get a response in the case I'm not accepted? I know I'm a little bit impatient here, but after 2 weeks of waiting, I'm not sure anymore whether I should keep waiting or simply give up.
