Which Microsoft office is everyone using at work?

I'm looking at changing jobs. Reception or admin type of jobs.
I did business admin courses years ago (Office 2007) but obviously time has moved on.jobs

What is the most used Office now? I'm looking to buy it and update myself before I start applying for jobs

Office365 and agree on SharePoint but I don't like it, I think it's only a matter of time before shared drives are gone though
