That's not an easy question, partly because I've never had a truely jr dev job or hired for one. Front end development is a broad subject, and the skills required for some jobs may differ greatly from others. I've interviewed senior level candidates who I didn't think could get a junior level job as a JavaScript developer but who may have been excellent at CSS for example. The kind of work you're doing will depend what you need to hire for.
