SAP Developer interview questions

I applied online. Got a call within 2 weeks. They were nice people and made and I found myself comfortable within no time. They asked questions in Java, Python and JavaScript, most of which I could answer. Later they increased the difficulty level, in which I was also able to answer those questions. By the end of the interview they said the interview was good and I did well and I could be getting a response from them within few weeks. I waited for almost 1 month, after which I decided to ask them for their response. They replied saying it would need more time, and again after almost 3 weeks, tired of waiting, I again asked them for their response. Got no response yet. Overall interview was good, but the process after it is too much time consuming.

Second round was paper based coding round where they gave two coding question on DS and basic pattern or array based questions . Third Round was Technical round where they had asked from OS , DS , C , C++ , JAVA ,SQL and everything you have gone through since last semester .
