Kaizen Analytix interview questions

The interviewer was late by more than 10 minutes, gave no introduction about themselves, the company or cared to ask about me. They dove straight to technical questions, asked about 20 technical questions (some of which was not even a part of my experience in the resume), and then live coding. It felt like a sprint, where I was scrambling to finish one, and before you know, they were jumping to the next.

Went through 5 rounds. In one of the rounds, they sent me a case study where my task was to analyze and provide recommendations. Straight forward even that the data set I received was not good (I think they used a dataset from Kaggle but they cut parts of it randomly without looking which parts they were cutting). When I presented the case, the manager didn't know about the data set and didn't know that it included one month not a one year data although he's the one who sent it! Anyways, I passed all that and moved from one round to another. They asked me for extra stuff and analysis and I had no issue to submit what they asked for on time even though I was on vacation. Finally, they asked me for a final round of interviews with the manager who is responsible for New York office ( I think he's a co-founder). He was not supposed to be my manager for this position. Not even a smile when I met with him. It was obvious that he profiled me from my name. He was putting a religion symbol behind him and I felt he didn't want to have this call. He asked me some general questions and didn't hear back from this company afterwards even though I followed up with them multiple times. I just wanted a formal decline at least as a sign of respect of the time I spent with them. So UNPROFESSIONAL -- STAY AWAY
