After a few calls talking about my CV and the company as well as the projects I was invited to take a test. It was an online test, live coding on HackerRank platform. It gives you only 1,5 hour to complete 3 tasks. The platform compiles incredibly slowly do don't make my mistake - code in your IDE and then copy-paste. There is just too little time so if you don't type quickly while thinking then this is not for you.
