Amazon Web Services ML Engineer interview questions

The first step was an online assessment, composed of three coding questions plus a behavioural test. The second step was a technical phone call with an interviewer. The third and last step was the onsite round, composed of 4 consecutive interviews. At the end, they don't provide any feedback. If you are rejected, they just send you a disrespectful "noreply" email, which doesn't help you understand what went well and what didn't.
