Three steps to go. Basically, they test how well you can deal with actual issues with the position and would hear how well you know about the company and the role. If you pass the first two steps, you can have an opportunity for the one-to-one interview. All the interviewers were very warm, welcoming, and friendly. The more you show your interest in the company and position, they will want to know more about you through additional questions and happily answer you whatever question you ask.
