SAP Big Data/Data Visualization Developer interview questions

I applied online in mid May 2016, and got email from recruiter in about two weeks and set up a phone screen. BUT the recruiter didn't call at the time so I followed up by email. Then we rescheduled the phone screen, but AGAIN, I didn't get the call for the rescheduled phone screen. So I followed up the THIRD time for rescheduling, and finally the recruiter did call. It only lasted about 10 min, and I introduced my background, and the recruiter only asked some logistic questions (e.g. time of availability, salary expectation etc.), and seemed very indifferent about talking to a candidate (didn't even want to introduce about this role). Very ridiculous experience.
