Hi Greg :)
1) To clarify, the theme can be translated into any other language, but is not multilingual in the sense that users can select from various languages. This is a possibility using a plugin such as WPML, and our team are working with the developers of that plugin for this as mentioned
here, however we do not currently have a time frame for when this will be available for JobRoller.
2) This essentially comes down to the
job listing queries that you create and will depend how you manage the various languages/countries - a single installation or multiple instances for each country (e.g. china/yourdomain.com, italy/yourdomain.com etc). You'd need to create many queries if you're using multiple countries on the same install. Thanks.
