I interviewed for the company in November, having sent a response before that. Standard interview with HR with standard questions about motivation and work experience. HR promised to come back with feedback in two business days but did not. My clarifying email asking for feedback was also unanswered. It's not professional that such a large company can't build a normal process for interacting with candidates. If even a potential candidate isn't a good fit, you can always respond with feedback instead of just disappearing and ignoring messages.

Relaxed, it's all about getting to know more about you. I was interviewed by both the HR manager and the team leader on the 1st round. And then by the manager from belgium on the 2nd round. Overall it was a great interview process.
