Interview Preparation Tips
I was informed by the HR team that my interview would be conducted in person, with all rounds taking place on the same day, and that I would receive the results the same day. As a result, I traveled a considerable distance to attend.for the interview the told me to wait for the 3 hrs.
- During the interview, it was disheartening to find that the interviewer seemed uninterested in my responses. I was asked to write queries on paper, and while I was explaining them, the interviewer was preoccupied with reading emails and all other work. Despite providing correct answers, the experience felt dismissive.
After the interview, I was asked to wait for feedback. After waiting for two hours, the HR team informed me that my review was still in process and that they would follow up. After three days and multiple follow-ups, I was eventually told that I did not clear the round.
While I am okay with the outcome, I have a few requests for companies conducting interviews:
1.Respect Candidates' Efforts and Time: Please be considerate of the efforts and time candidates invest, especially those who travel long distances.
2. Clear Communication: If face-to-face interviews are required, particularly for final rounds, please communicate this clearly to avoid unnecessary travel and inconvenience.
I hope these points help improve the interview process for future candidates.
