Interview Process

The interview consisted of multiple rounds. The first round involved coding on a laptop with a focus on file I/O operations. The candidate was required to read input from a file specified by a given path, where each line contained a word. This round lasted for about one and a half hours. The interviewer was described as impatient and unwilling to clarify questions, leading to a negative experience. After completing the coding task, the candidate was asked to run and validate their code with two examples provided by the interviewer.
