Applied online. Got an email later on with a series of tests. Some easy, some harder, Math test was basic but timed. Then came a test for pattern recognition where they'd throw you a sequence of figures and ask yout to select what the next figure in the sequence would be. Then got called in for interviews. First was a guy with some easy qs about finances and then a couple of minutes of timed mental math (tough). Then a more senior guys just asking regular interview qs.

An online assessment or two then a super day. Super day had 6 30 min interviews spread across the day. Not too hard individually, but it's an exhausting day. They were very nice to me throughout.
