Understand how GCP handles scalability, security, and cost management. Practice scenario-based questions to demonstrate problem-solving skills. Hands-on experience through labs or personal projects can be invaluable. Additionally, explore case studies to see how companies leverage GCP for real-world solutions. This preparation will boost your confidence and technical understanding.
