I was referred by a friend. The interview had two rounds, both online with a video call.

The HR round was very typical. They told me about the company and how they operate, some projects, and the training options. The HR lady was very kind, and we discussed a few questions in English.

The technical round was one hour long with a people lead who was also a tech lead. We talked for about 20 minutes in English about my CV and my previous projects. He wanted to know if I could discuss technical details of my work and my experiences. Then he asked about the frameworks and technologies that I mentioned in my CV. Make sure that you actually know about the stuff you put in your CV because they will ask about everything.

Then I had to explain the SOLID principles as if I were to tell them to a junior colleague. Some design patterns, multithreading, and front-end questions.

The interviewer was a super nice, chill person. He made sure that I was comfortable during the interview, and he told me that he did not mean to embarrass me by asking something I do not have experience with.

I got an offer the next morning.
