Then interviewer shifted to os question. I didn’t revised my concepts in OS i told him about it, Still he asked about

Different Types of scheduling algorithms. 

Thread loop questions. 

I didn’t remember i answered any of these question perfectly. Just Prepare OS and DBMS as best as you can for OYO. 

There was 3rd round for few students. I was told to wait forr the result . At Last i was offered a SLI with OYO.
