Equifax Lead Java Developer interview questions

Very unprofessional. Not good. HR contacted me and arranged an interview with a junior java developer. I didn't expect a junior developer would interview me and also while driving back to his home. Even though I was good in one of the skills, he asked which other skill do you know other than this known skill. He didn't know much about hadoop and just argued there is nothing to to do from application point of view in order for it to work in secured hadoop environment; he said just the secured hadoop environment should be setup.
