I answered the 90% interview question. Why is it rejected?

This article was found on the shopping spree and was inspired to repost it here. Address: http://www.mitbbs.com/article_t/JobHunting/32327557.html

 

During the exchange interview, some people often ask a question: I answered 90% of the interview questions correctly. Why was it rejected?

We will discuss this issue.
Answer one of my questions:If the full score for an interview is 100, how much should you score if you answer 90% questions correctly?
If you think the score is 90, it means that you have not understood the interview, and there is no difference between the interview and the examination. The exam is to see if you are qualified, and the interview is to select the best one. Use the exam thinking to deal with the interview, buddy.

Now I want to answer my second question. If 10 people in a certain position can answer 90% correctly, why should they ask the other party to give you an offer? If you cannot solve this problem, your future interview success rate will always be 1/N (N indicates the number of people at your level when you compete for the same position ).

Have you ever thought about the following situations in your competitors:
-Someone can score 100 or even 150 points in an interview with a full score of 200.
-Someone can answer a question with 10 points to 50 points.
-Someone can use the wrong answer to defeat your correct answer
-Someone can take the offer from you with questions that he doesn't know.

For me,Correct answers to all interview questions can only be regarded as pass.
If you want to take advantage of the interview, you must: Get out of the questions, get out of the correct answers, and get out of your limitations.

How to get out of the question?
At another interview meeting, I asked the conventional question: are you good at independent development or cooperative development? There were 90% people on site who chose cooperative development. They believed that cooperation was needed by modern enterprises. 10% select independent development, indicating that the ability is strong and can be independent. At my prompt, someone was brave enough to choose both of them. I asked: "Are you both good at this? Who believes it ". The classmate was speechless immediately.

When 90% of you answer the same question, no matter how correct your answer is, it is useless.
When selecting A or B, have you ever thought about the two most direct options? You can also:
-Select both
-Both give up and select C.
-Select A for 30%, and B for 70%.
-.......

My answer to this question is: I am good at both cooperative development and independent development. I joined a project in a company in a certain month and cooperated with multiple parties to achieve excellent results. A month later, the leaders asked me to complete a task independently. After more than N attempts, I achieved amazing results.

By the way, I have never said "I am in a project" during the interview. The projects I mentioned must be: Time, place, people, events, and results.

Another example I often use: Write an SQL statement to delete a user from the Users table.
Correct answer: delete from users WHERE id = [userid]
After most of the students answered correctly, they returned home and waited for good news.
Let's calm down and analyze,Can anyone who has learned SQL for two days write this statement? This is a correct answerIt is useless even if you answer 100 questions, because it can only prove that you are a beginner.. Note: I am not saying "you are a beginner", I mean "you are a beginner"

Check whether the answer is better: First delete other data associated with the user, and then delete the user data.
What's better? Not only is the answer better, but it also shows "I have database experience"

In my experience, we never really delete user data. We only update the user status.
UPDATE users SET active = 0 WHERE id = [userid]
The answer clearly tells the other party that I understand both SQL and database, have project experience, and can use it flexibly.
Now let's take a look at the first correct answer. Is there any advantage?

In fact, many of my friends knew it early, but they couldn't tell it during the interview.

Some people will be curious. The interviewer asked SQL, would you expect to answer your project experience? During the interview, if possible, I will try to answer questions as far as possible. Only in this way can the question with 10 points be answered into 50 points.

This actually explains a phenomenon,Why does an interview fail to get an offer? You feel good becauseEasy questionHowever, if the question is easy, you will answer the question in an easy way, and ignore the available space.

I often say that there are no easy questions in the interview, because it is easy for you and others.
One principle,The questions that are easy to answer during the interview should be "a big question"

A question can be answered in many ways, and each answer can be answered in many ways. The interviewer can choose the best answer based on their own situation, the other company, and the best time.

For example, I interviewed a communication company during my 4th day, and the interview was arranged at night. One interview: Do you know the OSI Layer-7 protocol? I suddenly realized that we just completed the "Communication Principles" examination that afternoon. That is to say, all of my competitors (my classmates) are capable of turning back. So I replied: I know OSI's layer-7 protocol, but I can't remember the specific sequence. Let me take a look: at the bottom, the NIC network cable is the hardware layer. After the hardware is set up, the data passes through. The above is the data link layer. Once the data is connected, the network protocol can run, then the network layer ........When myI want to show my competitors to the interviewer.

Some people may ask, what if the answer to a simple question is so complicated and the time is not enough? I remind you again, can you separate the interview from the exam? If the exam time is not enough, points will be deducted if the questions are not completed, and the interview time will be controlled by the interviewer. If the interviewer has prepared 10 questions, the first five questions fully demonstrate your abilities and qualities. Do you need to do the last five questions?

Another example is that a friend of mine interviewed a Java job in Montreal (French), Canada. The question is: What is the difference between Abstract Class and Interface?
My friend replied: Class indicates "yes" and Interface indicates "yes.
Although the answer method is somewhat unconventional, I forgot the proper time and location. A Chinese-speaking applicant, a French-speaking interviewer, and two people discuss the relationship between "yes" and "yes" in English in both languages. Can you understand? If you cannot understand it, the other party certainly thinks that you are not clear about it.

Whether in preparation for the interview, interview, or analysis. We must clarify what the other party asks you?
What did you answer? If you are still thinking about the correct answer, go back to the beginning and repeat this article.You must make the analysis clearParty A's question is what kind of ability should be tested again, and all your answers contain the ability, whether it is sufficient, whether it is exceeded, and whether it is unexpected.Surprise?Only in this way can we prepare for an interview with top 10 questions.

My friend and I talked about one interview question: Now there is a house in Beijing, and the price is 2 million. If the house price increases by 10% every year, a software engineer will earn 0.4 million yuan a year. If he wants to buy this house, no loans, no salary increases, no other income, no food, no consumption every year, then how many years does he need to save enough money to buy this house?
The answer: A-5 years; B-7 years; C-8 years; D-9 years; E-can never afford

The correct answer to this question is that E can never afford it.
When I figured I could never afford it, I immediately realized that all of my competitors would choose E. In this case, there is a sudden whimsy, and there is no work und. That is to say, when someone else answers "impossible", I answer "possible ".
One solution: an option and a contract with the Homeowner: seven years later, I bought a house worth 2.8 million yuan.
In reality, not everyone decides that the price will always rise rapidly, and someone will be willing to sign the contract with you.
Find the second method: installment payment, the first year to buy 20% property rights, the second year to buy 18.18% property rights, and three years to buy 16.53% property rights ,.... The full amount can be paid in 7th years.
Someone questioned: Are you sure the law permits you to buy a house at 1.1 points like this? We are going to interview IT migrant workers, but to make full use of our creativity, not to apply for a lawyer.
Find the third method: buy a small house with 0.4 million every year, sell all the small houses in 7th years, and buy a large house again.

As long as you are willing to break the boundaries of the question, you can find many "possible" methods. I admit that I did not answer the correct answer. But to be clear, the other party wants to test my mathematical ability. My answers show the mathematical ability, the breadth of thinking, and the flexibility to deal with problems. In this way, my incorrect answers can beat the correct answers.

In another example, when I graduated from college to apply for a job, a Chinese company said that I would like to take an exam. I said that I am not good at such questions, and the other company insisted on taking the test. The question is: a child is on the 17th floor. He goes home every day and takes the elevator to the 15th floor. Then he goes home on the second floor. Why? I thought about it and said I don't know.
At the end of the interview, the other party asked me a question. I said, "Can you tell me the answer to that brain teasers? I want to lose my understanding ." The answer is: the child is less than 17 layers of buttons, only 15 layers.
I laughed and said, "No wonder I cannot answer this question. It turns out this kid is mentally retarded! A three-year-old child can't get anything and knows how to move a small bench. This child can go out on his own, at least six or seven years old. I don't want to go to any difficulties every day.
Methods? A brick in the elevator room, with only a pen on it.
I turned to the interviewer and said: If I am lucky enough to be hired by your company, we will be colleagues in the future. Isn't my work around me at this level? (In other words, if you use such a mentally retarded question to test me, your IQ is too much .......)

The other person asked this question only to test the question. My answer is: I am not smart, but I have eloquence, logic, and adaptability. Finally, we despise the following question to show the pride of young people.

During the interview, find out what the other party wants and return it to him. "Cast me to Mu Tao, report to Qiong Yao" (misinterpreting these two poems)

Many friends like the classification of interview questions, such as personnel questions, concept questions, experience questions, and behavior questions. For me, except for the code question, other questions are basically not classified, and the answer method is the same: answer in the best way for me.
You asked me about technology and mixed experience. You asked me about my experience, and I rubbed wisdom. You tested my wisdom and I showed my care.
Most of my interview answers are mixed with value-added content. I use value-added content to get an offer from others. In fact, you don't need to be good at everything. As long as you add value appropriately, the odds are greatly increased. Most people answer questions only in the question. If you are playing with additional value, you are already ahead.

In actual interviews, not every interviewer can correctly interpret the value added from your answers, but he will feel that your answers are better than others, as for the good news, sometimes he cannot tell. Of course, there are also interviewers who have no feeling about the added value. Do you need to mix them with him in the future?

In most cases, you do not have to go too far. You only need to take one or two more steps than other applicants. Assuming that everyone's level is equivalent,When you encounter a question, other people can think of it.In this case, do not rush to answer questions., Find a better answerMore than half of the people were dumped.

Another example is also a vulgar question: why do you choose our company?
Most people use reasons such as family reasons, personal interests, and friend introductions. These answers are all congested and there is no difference between answers and no answers.
I will answer this question: the IT industry is changing. In the next 5-10 years, mobile device and online service will become the two fastest growing fields in the IT industry. I think your company's products will have a place in the future world. This is my primary reason.
Analytics, foresight, and decision-making, while still cool and cool.

Do not waste any question or chance. Almost every question has room for use.

We are looking at the interview from another perspective. For example, if you want to hire a chef in a hotel, apply for the following:
A. You can check the recipe on the Internet to make dishes that taste good.
B. skilled knifE workers, excellent ingredients, Master mainstream cuisines
C. Learn about each cuisine and adjust the ingredients according to the season, region, and guests.
D. You can develop new dishes based on the characteristics of existing cuisines.
E. Learn about the origins and development of different cuisines and their impact on culture in different regions.

Now, who is most likely to get an offer?
-A may have better dish than B, but A has almost no chance of offering it.
-B may be a good cook, but it is difficult to become the main character of a big restaurant.
-When B competes with C or D for a famous store position during the interview, the odds are not big.
-E, although high, does not seem to be useful for most restaurants. That is to say, the bigger the game, the more opportunities there are.
Let's look at some interesting phenomena:
-A can see that B is better than himself.
-In B's view, it is king to master more dishes
-No matter how B is trained as a knife technician, it is impossible to become C because the idea has not come out.
-In B's view, some errors of C are "Incorrect ".
-The requirements for C and D are not high.
For B, it is necessary to meet two conditions, so it makes sense to work hard:
-The store only wants to recruit a hacker.
-Competitors also play the cutting-edge game.
For most people, it is difficult for us to become C and D, but you can dress up in the interview. From the perspective of C and D, the success rate will increase if you say a few words in C and D.

Now let's talk about the code. I have never prepared code questions before. I know that DP has been a task for nearly a year.I'm not talking about codeThe question is not important, but do not just stare at the code question. If you think that the code is king, your thinking will be "Capped"Like the previous chef who worked hard.

Many of my friends only focus on two things: Core algorithms and bug free.
For me, the Core algorithms are important, but they are only 20%. I never think about bug free. The reason is simple. I can't do it. Even if it does, it's just a bug free. In contrast, the following entries are more important because they are associated with your experience:
1. Have you understood the question and asked the question before you start?
2. Is the idea on the correct track?
3. Good naming habits
4. Whether the general and special circumstances are taken into account
5. Is there any targeted optimization (time, space, or other)
6. Are all concepts involved in the code correctly used.
7. code readability, maintainability, and scalability (testability ).
8. Complete the code to clearly understand the advantages and disadvantages of the code and when errors may occur.

Sometimes,For a certain code question, it is risky to optimize the writing if it is conservative. MyThe choice principle is: Check whether the conservative statement is sufficient to show yourself. If it's just an entry level, I 'd rather take it.Risk optimization.In other words, the interview is not an exam, and right or wrong is not important. For many interviewers, I am trying to optimize it more important than making the question more important.
Sometimes, even if you are not really optimizing, just say "Let me see, there is no possibility of optimization ". It can also make a good impression on the interviewer.

I often say that if you find that the core algorithm of the Code is multiple loops, you should stop writing.

There is a post on the Internet that says "see yourself, see heaven and earth, see sentient beings"
For me:
See yourself-find the most correct answer for each question
See the world-find the most favorable answer and answer method for each question based on the day and location
See the sentient beings-deal with the interviewer, squeeze out competitors who are higher than their own degree of education, strong ability, much experience, and fierce questions.
