I was talking to a recruiter about a possible role with a company and she said she'd put me forward for it. The recruiter works with that company but not for that company, and there has not been any contract between me and the recruiter either. Since talking to the recruiter about the role, a little more than a month went by, and I never heard anything back so I assumed their client wasn't interested, and forgot all about it.
Then I saw an advert for a different vacancy, and I applied directly to the company. Now the hiring manager there likes my CV enough to invite me for an interview, and apparently tells the recruiter about it.
Then the recruiter e-mails me to ask why I didn't tell her. And I reply, saying essentially "I've been applying for a lot of positions lately, don't remember all the names, must've just gone ahead without checking with you. Sorry, I didn't mean to cause you any bother".
How should I proceed with this pursuit? Should I try and involve the recruiter again? Or shrug it off?
