Interview: It takes seven days to pay for a gold bar. How many times do I have to cut it off at least?

In the recruitment interview of multinational enterprises, there are often wonderful interview questions, focusing on the thinking mode and thinking transformation ability of job seekers. Because this ability is related to the state of strain and innovation in work. Answer this kind of interview questions, and be brave enough to break the mindset.

Many years ago, Microsoft had an interview question: you hired someone to work for you for seven days, and the salary was a gold bar. But this person requires a gold bar every day, and you should also pay your salary every day to ensure the completion of the construction period. How many times have you cut gold bars at least? Not long ago, there was a company that imitated this problem on both sides.

The first candidate pondered a little, "I think it should be cut six pieces, with an average of seven pieces, and give employees one piece every day, so that the daily salary will be paid." The interviewer listened, deadpan, waved, next.

The second candidate thought for a long time, "Why can't I put myself in others' shoes?" Don't cut it once. I will mortgage the gold bars to the bank first, for example, exchange them for the equivalent currency of 700 yuan, and give employees 100 yuan every day. On the last day, employees were asked to redeem gold bars with 700 yuan. "This kind of thinking change is a bit big, and the interviewer is shocked. He didn't reflect it for a while, but he still thought it was beside the point. Wave and ask for the next one.

The third candidate, a doctor, replied without thinking, "At least twice. Cut the gold bars into one-seventh, two-seventh, four-seventh and three sections. On the first day, give employees one-seventh of the money. The next day, I gave two-seventh paragraphs and asked for one-seventh paragraphs. Give one seventh on the third day. On the fourth day, four or seven paragraphs were given, and one seventh and two seventh paragraphs were returned. Give him a seventh on the fifth day. On the sixth day, give him two-sevenths and ask for one-seventh back. Give him a seventh on the seventh day. "

PS: The doctor's answer was recorded by the interviewer in seconds. The doctor's way of thinking has been changed, and he can give the staff gold bars or take them back, thus forming a turnover of gold bars, and cutting them twice is enough. If you are a job seeker, is there a better answer?
