I applied online. The process took 4 weeks. I interviewed at Barclays (London, England) in Nov 2018
Interview
first apply online and receive an online test invitation for general numerical analysis, then video interview that consists of questions for specific role, then coding test, and final onsite interview that takes almost one day
The interview contains several questions about explaining the context including finance, stats (regression and prob) and ml. The questions are not very hard but need to be explained carefully and clearly.

Question 1
Some questions about concept for example the Bayesian theorem.
3 rounds, two technicals + one behavioral, not hard for the content, but very hard to get selected since headcounts are so limited. All the interviewers are nice and kind. good experience with a bad result.
