Fujitsu Software Architect interview questions

The first interview (with HR) was very professional and positive. The second (technical) interview was little strange. No questions about technical background. One technical question. And lot of questions about my preferences (Which OS do you like? Which framework do you like between JaveEE and Spring?). I was little disapointed, because choosing Java developer by desktop OS preference is very unprofessional, from my point of view.
