Cloudera Senior Software Engineer, Test and Automation interview questions

I've connected to Cloudera internal recruiter via LinkedIn. The process took approximately 2.5 weeks before phone screening interview. On the phone I was asked to design in-order iterator class for a BST. That went well, and I had on-site inerview afler a week. On-site lasted 5.5 hrs, with 6 people. The QA director had half-an-hour, the rest 1 hr each. Besides director and hiring manager, who asked me general behavioral and QA methodologies questions, it was mostly algorithms and coding on the white board. Everybody was very friendly and helpful. The atmosphere was great. Hiring manager took me to lunch. And I even got goody bag to take home :-) Unfortunately, my coding skills were not up to their standards, and I've got rejected.
