An offline test was conducted before I had a face-to-face interview.

The offline test involved creating a small project.

I was interviewed in Potsdam and had to go through three rounds of interviews.

1. Technical Round: (Tip: Know your basics; design patterns are important.)
2. Case Study Round: (Tip: Know your domain. I was asked to explain the complete architecture of my previous project, including hardware limitations and the pros and cons of moving it to the cloud.)
3. HR + Manager Round: (Tip: Be prepared for questions on your notice period, salary expectations, and motivation.)

Each of these rounds lasted for one hour.

What is the Strategy pattern?
