They asked me to tell them about myself.

The first sentence in my speech was about the length of my experience, and the second sentence was about my tech stack.

My speech was not monotonous and not too long (less than a minute).

I was interrupted before I finished my 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.

Finally, there were standard questions, like what challenges I met.

When I asked whether the team uses Greenplum (it's not in the requirements), they answered with one word: "no".

After an hour, I received a rejection email.

Tell me about yourself.

The Greenplum is mentioned in your CV. In what way did you use it?
