I mean if you are somewhere 1/3 of the whole day you naturally get to know the people you are around everyday. As well as the fact that you already have a filter of commonality, everyone I work with already has been filtered to live in the same town, at the same company and is also a fellow engineer. No one's harassing someone into dating them due to being around them a lot and if they did that sounds like some type of #metoo situation and probably would get you fired pretty quickly nowadays. If you don't want to date a coworker you are free to not date them but I don't see how, for example my coworkers that just got married have an inferior relationship because they didn't meet 'naturally'. In fact I would consider getting to know someone by talking to them everyday one of the most natural forms vs meeting someone online.
