I think that if the company is the sort of company that is interested in online reputation, they will also be well aware of the negative SEO that can possibly happen and are usually good at being able to tell when it's happening/happened.
I wouldn't worry about it to be honest and if you're really worried that is going to have an impact on what the outcome of your job interview will be, just slyly mention it or bring it up, so that in the back of their mind,t hey know what's going down. As long as you have been targeted and not just lying, as that won't end up going well at all!
Good luck wither way!
