My interview process for SQL and API development starts with an initial screening where a recruiter assesses my background and technical skills. This is followed by a technical assessment to evaluate my proficiency with SQL queries and API development through coding challenges or take-home assignments. Next, there is a technical interview with engineers focusing on SQL concepts, database design, optimization techniques, as well as API design, REST principles, and implementation. Finally, a behavioral interview evaluates my fit within the team and company culture, with questions about past projects and collaboration experiences.
