The interviewer was very experienced in mainframe and cloud (20 years exp). He was more focused on cloud technologies, less on other stuff like CP/DSA. He gave me a question and immediately after my answer, he gave me satisfactory answers. He grilled me on my cloud knowledge; luckily, I had a project on my resume, so I survived there. Apart from this, I would suggest having at least one big project that you can explain in-depth for a long time. For example, in my case, out of 45 minutes of the interview, at least 20-25 minutes I spoke about my projects and contributions there. The rest were some basic core questions, and then the results were told just after the interview by other team members (selected or not). Some of my friends had system-design-heavy interviews. Luck matters!
