I applied online.

The HR department called me and appointed an interview at their offices.

They told me that the process should take up to an hour.

The interviewer asked me to introduce myself and speak about my projects, resume, and work.

The interview consisted of two questions. It is important to solve them in the minimum time, not to be delayed with the answer. So, when you prepare for the interview, solve them in an exam simulation.

Also, they mentioned that this job is not defined as R&D in their company.

You have a black box which sorts 2 numbers: big and small (an output of a box: smallest and highest). The question has two sections:

Section A: Create a system which sorts 4 numbers.

Section B: Make your previous system sort 5 numbers.

Different question: Write a code which performs the '7 boom' game.
