It was very technical. You willl need to know broad range and depth of the role. I will highly recommend to know your cv from top to bottom as well as the job description.
The process took 3 months. I interviewed at Kookmin Bank (London, England) in May 2022
Interview
Overall interview questions themselves were quite straightforward. Basic understanding of loans is good to have. General questions on knowledge gained through education and internships. Interview process can be dragged on for a long time.
