The interview consisted of two exploitation rounds and one design round.

There were significant gaps between the exploitation rounds. The design round focused on the systems that were implemented.

The interviewer seemed unreceptive to listening and was primarily focused on covering his predetermined questions, rather than engaging in a two-way conversation. He also exhibited a dismissive attitude and lacked humility.

The interviewer appeared confused when discussing and explaining the different architectures.

I don't believe he fully grasped the scope of the various problems involved.

No feedback was provided. I would not recommend this interview process.

Designing scaled-up systems.

Skipping this to keep the questions within the org.
