Johnson Controls Developer interview questions

It's a on-campus interview for MTech student where 21 students were selected by a MCQ test based on core CS questions. I thought interview would be based on DS or project as it's an sde role, but everyone was asked DBMS and SQL query and project related questions, literally everyone. And only 7 were selected for HR round, 3 students got the job and 1 got the internship.

My experience of interview is good, Below is the interview process 1. First Round is Technical Round Type of Questions: Basics of technology, Scenario based questions, Conditional questions Difficulty: Medium/ Moderate 2. HR Round Salary Negotiation
