Answer:
False.
Step-by-step explanation:
In an interview for a job, there is no specific rule to be followed that an interviewee must follow. An interview is a perfect time to get to know more about the company's needs and also to advertise yourself.
But in case the job is no something that you like, then you must call the interviewer back and thank them for their time and also tell them the reason for the job rejection. Moreover, it is unethical to abruptly decline any job offer. Also, rejecting a job during the interview is not a standard procedure, for it will only make you seem more unethical and disrespectful.
Therefore, it is not true that rejecting a job on the spot during an interview is a standard procedure.
