Dart Container Software Development interview questions

SAP Position. Half of the questions are NOT behavior questions. I got interview from two different teams. They use WebEx. Always on Friday. The recruiter from the second team can not access the microphone of WebEx (Can't believe it……), 5 min later they decided to postpone the interview. On the job description, there is no specific team information, but in the interview, both recruiter from two teams asked questions like "We are xxx team, there is no background on your resume, tell me why you have interest in this position ?"……Definitely, you can not answer you have no interest in their position, then you have to try to give them a reason, and after that they would ask you a lot of very detailed questions regarding specific concept on the textbook or things you would record on your notes, rather than remember in your mind everyday. The whole interview let me feel they do not care or respect what you did from your previous experience (I do have SAP experience). After the interview, you just got a feeling - why there is so many things I do not know! Seems like they forget no body no everything regarding SAP! The whole interview process is just waste of my time.
