SAP Software Developer interview questions

I had total of 5 rounds. 1st and 2nd Technical followed by 1 Managerial round , 1 LOB round( someone from different business line / Team will interview you) and final HR round. I cleared all rounds. It was worst interview experience. Hr person was way too much rude. After 1 month of selection and follow up mails of Documents required, I was told that Position became inactive. Advice to Management: If you are trying to hire 4years experienced person then please respect their time and if you are not sure about position then don't call for interview and waste candidate's time.
