The second stage (online assignment) was quite easy. Questions are logic-based and you have plenty of time. There are 2 parts, tests and coding tasks. For some of coding tasks you can use only python, but they are very easy, and they give you python-sample.

Multi-stage interview. First you upload your CV, then next stage is technical where you need to solve LeetCode style questions and you are constrainted by time (around an hour I believe), then the next stage you need to answer loads of soft skills questions and record your self answering a few of them. Last stage is about assessment centre where you work with others and come up with solutions to problems.
