Initially the process would be some tests done in a 100% automated way. I passed all of them, including the main one which was the coding challenge, and to my surprise without any justification two months later they told me that I was not able because they had "manually reviewed" my test and I had not passed, yes, 2 months later. Besides that they told me that I would need to wait another 3 months to try again, but I did it in an event promoted by them, Jump Start, where even if I failed I could redo the test in 48 hours. Turing lacks transparency and clear rules, the rules change all the time according to their wishes.
