Varonis Systems Presales Engineer interview questions

First I have been interviewed by their HR. Then phone interview with a manager from US. It was fun and challenging with many security related questions. I have passed successfully. Then I had a phone interview with two managers from Germany. They also asked multiple security related questions and also challenged with some questions about the role. They promised to meet me in person but never came back. Quite weird because cybersecurity field is a small world and we can bump on each other in future.
