Turing Software Engineer interview questions

You have to create a profile in their application. After the profile, there would be online coding challenges, then a lot of tech stack tests. After you complete these tests and update your profile. You have to wait until they respond back. I got an invitation for a call with their internal recruiter and she said they will match you with the client within 4 weeks. It has been already 4 weeks and never heard back from them. Got contacted after 10 weeks saying you have not passed the Coding Challenge. Even their system congratulated me on passing the test. After wasting my 10 weeks with them, they just realized that I have not passed the test. That seems totally unprofessional to me.
