I should say first- the process is very long. I applied from the official website and got a notice for a video-recording interview after a week. There are about ten questions, and I had time to prepare 30sec and 90sec to talk for each. After over a week, I moved on to the next interview via phone which took about an hour. It'll be fine if you fully understand the job description, but the HR also asks you about the product range (Apart from the terminal) and recent financial news. I couldn't give the perfect answers for these but passed as I could show genuine interests and passion. After a few days, HR told me about the next round with the team leaders (each from analytics and sales) and the feedback of my phone interview. Before the face-to-face interview, I was also invited to the open day to talk with the analytics team. The team leader interview took about an hour, and it contains a lot of "What if" question that you have to answer with the required skills for the position, the estimated situation based on your understanding on the job, and how you approach it based on your experiences. I couldn't pass this, but there are two (!) more if you are successful. For me, the whole process took over 2 months. Further, I came to London from North East for two times (open-day, and an inteview), so bear in mind the transportation fee if you come from outside London
