The tactic of applying to as many companies as possible and taking all offered interviews can lead you to place where you have to make a tricky decision. When you're at a job interview and the interviewer offers you a job on the spot, you might want to hold out for another company's offer. The key to keep from offending the company that's extended an offer is to be gracious and respectfully request some time to think about the offer.
Asking For Time
If an interviewer offers you a job during an interview, avoid accepting it on the spot -- even if you think it's the right choice. Instead, ask for some time to think it over. If you're waiting on an offer from another company you've interviewed with, tell the interviewer that you are excited about the offer but that you've also interviewed with another company and you need some time to consider your options. The interviewer might give you a up to a week to make your decision. If you prefer, ask the interviewer whether you can get back to him with your decision on a specific date. However, don't ask for more time than one week or the interviewer might decide to offer the job to someone else.
Talking to the Other Company
Call the other company and ask to speak to the person with whom you interviewed. Tell the person you have received a job offer and you need to give them an answer within the week. State that you are very interested in the opportunity he has and ask when he will make a hiring decision. You might find that the interviewer is uncertain about a date for a hiring decision or he might say that the decision won't happen within the week. He also might say that he is planning on making a decision within a few days. Whatever the case, if you would rather take the second company's offer, make it clear that you are waiting on a hiring decision before you accept another job. Ask the interviewer whether you may call him back within a few days to check on the status of the decision.
Asking for Additional Time
If you've followed up with the second company and the interviewer still hasn't made a hiring decision, you can call the first company and ask for additional time. However, you might not get the response you want. The first company probably has at least one other candidate who is eligible for the job offer, and the interviewer might decide to withdraw your offer. Keep in mind that the other candidate is also waiting for an answer, and could move on if the interviewer doesn't give her a timely reply about the status of the job. Also, the interviewer will be aware that you are stalling because you are waiting to hear about another job offer, so it will seem as if you are more interested in what the other company has to offer. It all depends on whether you can afford to pass up a decent job opportunity in favor of one that might never materialize.
Making a Decision
If the company you are waiting to hear from about a job offer doesn't respond within the time limit given from the company who offered you a job, you have to make a decision. You can accept the offer that's on the table or decide to decline and wait out the other company. Be advised that the other company might never offer you a job.
就是說要權衡你自己的利弊，無論是說還是不說，都要保證自己利益的最大化，不要竹籃打水，兩邊都落空了。
