Test with basic math and language questions. We participated in small groups of 6 people. The test (although described as eady) was demanding. We had about an hour to complete.

I did 4 interviews 1st : With manager to talk about my CV and career path 2nd : Case study with team and R&D for technical questions 3rd : Online skill test 4th : HR interview was very basic, questions were about hobbies or why do you want to leave my current company. I was excepting more challenging questions. Hr told me me that they were deciding between me and other candidate and will let me know in 3 days. And I never received any feedback from HR ( even I wrote many times )
