Catching cattle and crossing the bridge should be a means to achieve requirements. It is not like a real requirement in itself. The interviewer needs to dig out what the customer’s core requirement is and then give a good solution. My original answer missed a point that Huawei attaches great importance to: if it is clear that the cow is a customer’s pet and needs to be transported to a designated location far away across the river, and the customer originally hoped that Huawei would send the cow across the river, then Huawei’s marketing staff must We will dig deeply into what work the customer has for others to do after the cattle cross the river, and then give a better solution to make customer satisfaction exceed expectations, so as to start further cooperation. Of course, this is the job of marketing and sales. If it is an interview for R&D positions, you can remind the marketing and sales to ask more questions without going further. : First of all, the market must reconfirm the customer’s needs: clarify the reason why customers want cattle to cross the bridge, whether they want to eat beef or live cattle; if they want to eat beef, can they replace the cattle with beef of no lower quality If the answer is yes, the actual demand of the customer is to eat beef, and crossing the bridge with live cattle is no longer a customer demand that must be fulfilled. Experts are called to re-evaluate the solution. If you want live cattle, can you use cattle of the same quality on the other side of the river to meet customer needs? If the answer is yes, the actual demand of the customer is to live cattle on the other side of the river. Crossing the bridge is no longer a customer requirement that must be fulfilled. Convene experts to re-evaluate the solution. If it is confirmed that none of the above is confirmed, the cow is a customer pet and must be delivered to the customer’s new home on the other side of the river full of tails vigorously; in other words, the expert’s assessment is that the cow crossing the bridge is the best solution. Then the customer demand is refined into: send this 800 kg live cattle to the other side of the river. The difficulty in realizing the demand is: the bridge deck bearing only 700 kilograms. Good, the project leader (product manager) convened internal relevant personnel to start a brainstorming meeting, and the meeting time was strictly controlled within 1 hour. The following solutions were obtained during the meeting: 1. Reduce the pressure of the cattle on the bridge deck. Ways to achieve this include feeding the cows for a day; attaching a hot air balloon to the cows; 2. Strengthening the carrying capacity of the bridge. The evaluation found that the maximum load-bearing capacity of the bridge pier is 1000kg, and the load-bearing bottleneck of the bridge is on the bridge deck. It can be strengthened by laying pallets when the bridge is facing, and the cattle will be restored to the original state after passing; 3….Record the meeting conclusion, send it to R&D, and request R&D to give it Optimizing the plan, risk assessment, and avoiding measures. After a feasible plan is formed, the person in charge of the R&D project convenes a plan review, and optimizes and refines the plan according to the review opinions. If there are fatal problems or too many serious problems, the plan is reversed until the final The plan is confirmed by the market, and the market interface person confirms the feasibility with the customer separately, and the person in charge of the bridge confirms the release. After getting the pass instructions, they will be executed immediately, and the project leader will follow up in real time. The above actions must be formally recorded and filed for future reference. In the event of an accident, the entire organization will assume the responsibility and do its best to recover unnecessary losses. After Niu crossed the bridge, relevant personnel summarized the experience and cases for reference by colleagues. The conclusion of the meeting during the whole process may be very simple, but this meeting is still necessary. The purpose is to introduce the ability of the organization to reduce accidents and reduce risks. At the same time, it can reserve the resources of the entire organization so that various accidents can be dealt with in the process of crossing the river. Respond quickly. Let me talk about the hidden purpose behind this question: if the interviewer directly gives a specific and reliable solution, then this interviewer is more suitable for the basic level of R&D; if the interviewer gives a solution, not to say that he can finally If it is not achieved, you can be the project interface person; if the interviewer gives a full set of solution perspectives, he has either done his homework, or he can indeed lead the team to do the project. Tell me a little bit about the other respondent’s diss Niu Qiao question/interviewer’s opinion: Regarding whether Niu He Qiao is a good question, I think if I really encounter it in the interview, I still have to work hard for win-win cooperation, it is best not to face it. After I sent my email back to the company, I despised the interviewer. I sprayed it to show that I was very good. The professional circle said it was big and big, but when I went to the bottom, it was really small. There are encounters in the mountains and rivers, and there may be future encounters and cooperation. It is not necessary. And I think this question is pretty good in the interview. You think it’s a bit absurd, but in fact, doing engineering is like pulling a big cow across the bridge too much. Assuming that Xiaomao’s company is thriving and has money, he wants to buy a thermostat (equipment for temperature and humidity cycling to verify the reliability of the product), and the busy boss orders: Xiaomao, go buy a large thermostat and come back, I think we are old The third-party laboratory xxxx incubator that spends money to do experiments is good, and the money is enough. Can Xiaomao open Taobao/JD directly and buy a xxxx thermostat? If you buy it back and find that the laboratory door is 10cm smaller than the incubator, is it embarrassing to be unable to get in? I dismantled the door frame and dragged it in. It was found that the power distribution in the laboratory was 10% lower than that of the thermostat. Isn’t it annoying that the power distribution must be modified? When the after-sales service personnel of the thermostat were called to install after the power distribution reformation, the sales and service personnel commissioned the thermostat wiring and said in front of Xiaomao and the boss: Oh, this model is very old. , The volume remains unchanged, the size is 11cm smaller, the power consumption is 30% lower, the price is the same, and the installation, maintenance and use are very good. You see, if you buy the latest one, the door and the electricity are actually… Do you think the boss would really want to expel classmate Xiao Mao at this moment?
