I wasted my valuable time and a PTO.

A recruiter contacted me and introduced me to a role on a team in the Unity Analytics organization.

The interview process was as follows:

1. A brief phone call with the recruiter.
2. A 1-hour phone screen with a hiring manager.
3. A 5-hour onsite interview with five people, including the hiring manager, a developer, a data analyst, a designer, and a project manager.

First, the hiring manager was 10 minutes late for the phone call. What he first said was, "Ask me any question if you have." So, I said, "Let's introduce each other first. Let me tell you a little bit about my background." My first thoughts on him were that he is not organized. My mistake here was I should have asked more questions about the role and what he wanted to build with me. He didn't give me a clear picture of what he would do with me. He just kept saying, "Your background looks very close to what I'm looking for."

Second, the onsite interview was pointless. There were pointless and inappropriate questions for a person applying for a data engineer role. There was no question/discussion about system/database architecture. One of the interviewers even said something negative about a project that I would be working on if I joined. He said there was no need to have those features. One of the interviewers gave me an API doc about a strange programming language that seemed to be used for programming a chip that you could buy on Amazon, and asked me to write some code using the language. Really?

The hiring manager started from saying, "Ask me questions if you have" again. After a pointless conversation, he asked me to write an algorithm that could be used in a Go game. Sorry, I am not interested in this type of problem.

I took some interviews at some major tech companies in the past. Many of them asked me to solve problems that we could actually face in the real world or in live data systems. I learned a lot from those questions/discussions, which made me feel like I want to work with those teams or these people. But, with the experience with the team at Unity, no. I don't want to work with this team. Wasted my time.

Already described above.
