The interview process was well-structured and relatively efficient. It typically consisted of multiple rounds:
Online assessment / initial screening: Focused on data structures and algorithms, with medium-to-hard LeetCode-style problems.
Technical interviews (2–3 rounds): Covered core computer science fundamentals (data structures, algorithms, system design basics), along with problem-solving and coding in real time. Interviewers also asked follow-up questions to evaluate depth of understanding and optimization.
Project discussion: Detailed discussion of past projects, including design decisions, trade-offs, and real-world impact.
HR / behavioral round: Focused on communication skills, teamwork, and cultural fit.
Overall, the process emphasized strong coding ability, solid fundamentals, and the ability to think clearly under pressure. Interviewers were generally professional, though the difficulty level was on the higher side, especially for algorithm questions.
