First I had to fill the online application. Second stage was a psychometric, numerical and IQ online test. After I had to do a phone interview with a person from HR. The last stage in which I did not manage to reach, is the assessment center in London. It was too demanding for the position and as far as I understood it is extremely competitive. Even if my online score tests were successful as well as my phone interview they probably are looking for individuals who graduated from high ranking universities. Bare in mind that I have also a masters which is not required for the latter position.
