A ridiculous process, punctuated by the fact that one of the interviewers in my loop was a senior data engineer who seemed to lack knowledge of basic data modeling and warehousing theories and concepts.

This interviewer also had difficulty speaking English, and I spent half the time trying to explain concepts that she couldn't comprehend due to her poor English proficiency.

The technical questions weren't that difficult; what's tough about the process are the redundant leadership questions. They tend to ask the same question repeatedly across different loops and expect a different answer each time.

Suffice it to say, I didn't get an offer, and that's probably a good thing. It's not hard to see why there's so much employee turnover there.
