Should I keep following up with this guy who offered me a job?

Asked by Anonymous - 1 week ago

I went to a talk a few weeks ago and I met one of the speakers afterwards. He's the CEO of a start-up and we spoke for about 30 minutes about his business and how they've literally just started hiring lots of people for the product team. I told him I work as a product manager myself and he asked me a few basic things about university, experience and that sort of thing. At the end he gave me his business card and said he thought I'd "fit in" at his company and I should email him my CV. Anyway I emailed him the CV and he replied saying "thanks I'll pass this on to our team lead". No response for 2 weeks so I sent a follow-up. Still no response. Should I keep emailing him or just take it as a rejection?
