The interview process is pretty straightforward. They mainly ask questions from your resume and fundamental data engineering concepts. It's recommended to focus on one cloud platform, as questions will be tailored to that. My experience was positive, and the interview concluded within 30 minutes. If your fundamentals are strong, you'll find it quite easy.
