I had a recruiter call, followed by a hiring manager call. Later, I was given a take-home coding challenge where I was provided with data and asked to solve some questions.

I gave him two perfect solutions to the coding challenge, using two different technologies.

I also had a follow-up interview with the hiring manager.

However, I did not pass the interview. There was no proper explanation for the rejection.

I felt the hiring manager was afraid of hiring me.

It felt like they were working with my employer and simply rejected me after wasting all my time.

Gave data to analyze. Asked to answer a few questions.
