First a short telephone call with a recruitment agency. Then a short call, a longer video interview with an aptitude test (verbal/non-verbal reasoning), another short video interview, then a final longer interview with a Software Testing specific test.
Each interview was about a week apart, so the whole process took a very long time. Although this was partially due to various people being on holiday.
Overall, I felt very welcomed throughout the process, with no sense of intimidation, which I appreciated.
