IBM SRE/DevOps Engineer interview questions

I applied for this position through campus selection, which had three rounds: a coding round, a technical interview, and an HR interview. The interview experience was really great, and there was no need to feel tense about the questions—they asked only what was mentioned in the job description provided beforehand. The interview started with a basic introduction about myself, followed by a question about my preferred programming language, to which I replied, "Python." They directly asked about OOP concepts and continued with questions based on my responses. If I could answer well, they would dive deeper into the topic. The interview was conducted online and had a very friendly atmosphere.
