Dida Machine Learning Scientist interview questions

Without an initial interview to get to know the company, they started the process with a take-home task right away. They specified that I should only hand in the results of the task, but after a week they requested the code, too. In the interview I explained my solution, discussed my past experience, and did a small coding exercise. After three weeks they told me that I wouldn't get an offer. Overall, the process was a little chaotic and starting with a task seems the wrong way around.
