Atlassian Java Technical Architect - Integration interview questions

I applied through LinkedIn for a relocation position. I was contacted by a recruiter after 1 (or two) day. First step was having a Java test online. Screening. This test was composed of multiple answers questions and coding. It wasn't easy, however it was fair. After less than a day the recruiter called me to tell me I passed with good results. He even detailed me the topics I made it wrong. Next step was coding online using Skype. I got some partially working system, added it to my IDE and for an hour we did TDD and pair programming while talking on the problems and how to solve them. I LOVED it ! Once again, after a day, the recruiter contacted me and asked me how I felt. I got the feedback again. A very detailed feedback of pros and cons. I really liked the feedback idea. Highly professional. Third step I didn't pass. I had an interview with a manager and a senior developer. They asked me about the system I am currently working on. I described to them, but apparently I didn't do very well. After getting feedback for this interview, I understood what went wrong. Most of the parts I just didn't explain very good. Overall, it was fun and interesting. Very professional interviewers and recruiter. LOVED their feedback system
