Prestatech Software Engineer Working Student interview questions

After applying for the position I got an invitation for an online Coding Challenge to solve. After „successfully“ completing the challenge I met the VP of HR which introduced me into the company and was open for all my questions. In the next I had a meeting with a senior software engineer where I had to solve a specific task. The engineer was very nice and helpful, he gave hints when being stuck and was open to answer questions. As last step I had the chance to meet the CTO. He asked me questions about my high-level software architecture knowledge.
