In our interview process, we have a few different stages to really get a good sense of a candidate's abilities. First, we start with an online assessment, which is usually a set of coding challenges or multiple-choice questions. It helps us gauge their basic coding skills and problem-solving abilities. After that, we move on to a more in-depth assessment focused on Data Structures and Algorithms (DSA). Here, candidates tackle more complex coding problems and theoretical questions to evaluate their understanding of fundamental concepts. Finally, there's the technical interview, where candidates work through real-world problems, discussing their solutions and demonstrating their knowledge of system design, optimization techniques, and relevant technologies. It's a thorough process that gives us a comprehensive view of each candidate's capabilities.

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.
