Software Improvement Group Frontend Developer interview questions

The first interview was by phone with the HR. The purpose of this interview was to know me better. The second interview was with the director of technology and HR. They asked me why I wanted to work there, what I would bring to the company, preivous experiences related to the vacancy, etc. Finally, I had the technical interview with two employees. This was a little bit weired because they gave me a piece of paper with a code to analyse.
