Colloquio
In my interview process is designed to thoroughly assess candidates skills in SQL, MongoDB, and React. For SQL, we focus on fundamental query writing, joins, normalization, and indexing. MongoDB evaluation includes CRUD operations, aggregation, indexing, and schema design. React assessment covers component lifecycle, state management, JSX, and routing.

Colloquio
My interview process for React involves an initial screening where a recruiter verifies my background and skills, followed by a technical assessment to evaluate my React proficiency through coding challenges or take-home assignments. Next, there’s a technical interview with engineers focusing on React concepts, JavaScript, and problem-solving abilities. Finally, a behavioral interview assesses my fit within the team and company culture, often including questions about past projects and collaboration experiences.
