Clive
Most "complete" scheme lists are nothing of the sort. They're the companies that paid to be on the list. Clive's directory comes from watching the whole market: every UK company over 50 employees, checked against their own careers pages. If a scheme is open, it's here. If it's here, it's real.
Job boards list whoever bought a slot and call it "the market". Clive builds this list the hard way, by reading every careers page in the country, so the brilliant scheme at a company you've never heard of sits right next to the famous one everybody applies to.
Schemes open, close, quietly reopen, and change deadlines without telling anyone. Clive checks constantly. What you see here is what's actually open, not what was open when someone last updated a spreadsheet.
This page is here if you like scrolling. The faster route is to tell Clive what you want. He'll read the whole list for you and come back with the handful that actually fit, reasons attached.
