Interview Process
The interview process began with an HR call on January 7, followed by an email to confirm availability. The technical review was scheduled for January 11. The interview was conducted by a senior engineer who started with a brief introduction. The candidate was given the option to choose between coding or discussing their project first and opted for coding.
The coding portion was conducted on HackerRank, where the candidate encountered a classic problem involving arrays and depth-first search (DFS). They experienced some difficulty due to forgetting specific details about the backtracking template but managed to complete the task. After finishing the coding challenge, they discussed their project for a while, and the interviewer shared insights about their own work experience. The overall atmosphere of the interview was relaxed, with the interviewer encouraging the candidate to look up the backtracking template online if needed.
