I participated in 3 stages:

• A phone call with a recruiter: The usual discussion, nothing special to mention.
• A culture fit discussion: Various questions about my CV, career objectives, and expectations from the company, but also a presentation about Dynatrace. The format was informative and friendly, not technical.
• A technical interview: Overall, a pretty relaxed format with a live coding session. However, like others have mentioned, it's risky to deviate from "how they want you to resolve the challenge," even if you're doing quite well. I definitely own my mistakes, so there's nothing to mention there. Nevertheless, when we had different opinions, they didn't really like it, even though both sides were valid. This is pretty common in large corporations.

Skipping to the technical session:

There were general knowledge questions from the software testing discipline, technical questions about my past experiences, and a live coding session where I was asked to write a test solution from scratch.
