3 stages, first stage is a hackerank hosted test called Revolut Ops Analytical test. This 1hr test is a mixture of numerical reasoning questions, basic applied stats and several open ended written questions. They recommend 90 seconds per analytical questions and 6 min per written answer. 90 seconds is not long for the analytical questions unless you know immediately the answer- thus makes it very hard to have the self discipline to allocate 6min for the written parts! Failed the test - would be good to know score or general details of performance, I never failed a test like this before
