Apple Data Engineer interview questions

They asked me to tell them about myself. The first sentence in my speech was about the length of my experience, the second sentence was about my tech stack. My speech is not monotonous and not too long (less than a minute). I was interrupted before I finished the speech and they asked me about the number of years of my experience and my tech stack again. Then I was asked about how I have used Greenplum, what kind of pipelines I used Greenplum for and how data was partitioned and so on. Finally, there were standard questions like what challenges I met. When I asked whether the team use Greenplum (it's not in the requirements), they answered with one word "no". After an hour I got a rejection email.

It was very tough than I thought. We have to strong in fundamentals and also programming. I created the resume for this interview to match with its JD. so then only you'll get the call.
