Interview steps with a phone screen (30 mins). The recruiter was an immensely polite, courteous, and fun person, probably the best I have ever experienced. Then came the technical screen of 60 mins, which was quite easy and smooth. I stumbled at the data the challenge (7 days), which admittedly was my fault as I didn't stick to the questions and failed to address the core last question with confidence. Throughout the entire team was courtious and humble. I didn't go further with them, but this should be a good place to work at with high moral standards.
