grizedale, the stage 2 is pure HR - no technical questions at all. Expect a stone faced "thankyou" to each question and no discussion!
You'd do well to read up on standard HR question banks, there's plenty around
on the net, there'll be some ones you can't predict or expect though so don't be surprised if you get one that you hadn't even considered.
There's not much you can do for that interview in terms of preparation, just make sure you can think up situations that you've been in recently that show off your good points
PS: hope it goes well neodude
