From an interviewer's perspective, the key is to assess the candidate's ability to apply security principles in real-world scenarios, particularly in cloud and financial contexts. They would evaluate technical skills such as designing secure architectures, writing secure code, and performing security reviews, while also gauging problem-solving abilities in balancing security with usability. Look for evidence of experience with tools and frameworks relevant to the industry, such as AWS security services or compliance standards like GDPR or PCI-DSS, and ensure the candidate demonstrates a collaborative approach when working with cross-functional teams. The focus should be on both theoretical knowledge and practical application to confirm the candidate can contribute effectively to Stably's security goals.
