A person is expected to answer to the best of his abilities in job interviews, exams, etc. It is also understood that at times a person will guess or make educated guesses. Despite knowing this norm, the company has offered this job to you. If you honestly feel you have spoken a clear lie, then make tawbah and istighfar.
