It was all good; they were very informative, and I enjoyed the whole process. Even though I didn't pass the first round, it felt like training for me. I had prepared 15 examples from my background, but unfortunately, during the interview, when they asked about the most innovative product I had worked on, it was from 15 years ago, and I couldn't recall all the details. They really delved deep. Prepare as if you are going to present to your own manager, who will ask more detailed questions.
