The process involved a lot of steps and many interview stages with HR and other people.

It seemed very disorganized and unprepared.

The process was strange, with a focus on brain teasers unrelated to the job.

While I understand that, I expected some conversation related to the actual role.

The people were nice, but the interaction felt awkward.

There was very little interest in my actual skills or knowledge.

I felt that they were trying to prove how smart they were, rather than consider me.
