IBM Softwareentwickler interview questions

I have a technical interview in Oct 2024 and it covered the basic knowledge on their tech stack such as node.js and Java. One algorithm problem, not complex but somehow tricky.

Interview started with the introduction, I told them about my projects. After that some OS and CN question answered all except one. after that they told me to open notepad and write a SQL Query. can't understand the first but did the second one. Asked to write a DSA problem on online editor as I completed the logic they asked me to explain it, I did. HR said the interview is over and asked if I want to ask about something, I asked about new cloud bridge of IBM, he answered. Interview end.
