In a three-round interview process comprising two technical and one HR round, the emphasis is on evaluating both technical skills and personal fit. Technical rounds typically assess problem-solving abilities and knowledge relevant to the role, often including challenging coding tasks. A difficult coding round suggests a focus on deep technical proficiency and the ability to handle complex challenges. The HR round serves to evaluate cultural fit, communication skills, and alignment with company values. Overall, this structured approach aims to thoroughly assess candidates' capabilities and suitability for the position, ensuring those selected can contribute effectively to the company's goals and culture.
