Can I hire and look for work with the same email?
Yes. The same address can have a job seeker side and an employer side. Signing in opens both, and each keeps its own applications, listings and settings.
If you are signed in as an employer and press Apply, the site offers to continue as a job seeker on the same address, with no new code.
Your applications belong to the job seeker side and your vacancies to the employer side, so look for each in its own place: My applications for what you sent, your account for what you posted.
On a shared or office computer, signing in closes anyone else’s account left open in that browser, so two people never sit in each other’s accounts.
