My very bad experience in the interviews started with two online interviews.

One was in coding. I was nervous and had difficulties answering (coding an iterator), but the next was in design and went very well (designing a calculator).

Yet, I received a decline. Later, they called me again for a different position. I passed the phone interview and they sent me a Codility exam. I completed all 3 questions almost successfully in 90 minutes. But with no explanation, I was declined again.

Microsoft's interview process is so frustrating.

I am very disappointed.

I really recommend considering if you want to go through such a frustrating process.

Coding an iterator by yourself.

Design a calculator and do some coding.

Codility with three different questions. 90 minutes.
