Self introduction
I have two books. I have been working for 4 and a half years. I can only get an outsourcing after graduation. Fortunately, the leadership is wrong and the project is also good. The mobile app of Bank of Communications has grown quite large. I spent nearly 3 years in it. I decided to try an Internet company. After interviewing 6 departments of a certain Dong, I finally entered successfully. It is still the core department of the order. It is a rapid growth here. At the beginning of this year, I was thinking about changing jobs. Jia Yuan, according to the classic quotations of the Fei Dynasty, has strong ability, willing to work overtime, and requires less money. According to the CAP theorem, he can only choose 2. In fact, the main reason is that the group has been a big boss for about 10 years. It is difficult for newcomers to get on the top, the rank is not promoted, the salary is not raised, then how to mix, it is time to go out, because now I am in a large company, so I think about the next one. At least you have to enter a company larger than the current company, so there are very few choices. There is no other choice except for certain li, certain news, certain article, certain group. At this point, the interview begins. . .
offer harvest
There were a total of 6 visits to a certain group before and after. In the first 3 times, all of them failed. Basically, they failed. The reason was clear. The algorithm did not pass. So during the Chinese New Year, a wave of evil supplements and a certain trip will be made after the year ( In fact, this interview was a bit because of the failure of the interview a year ago, the confidence was frustrated, and I had to face it first). After the pretence was over, I continued. I also interviewed a group three times, one time in a certain li, all of which were resumes on the same day, a week. After all this was done, it turned out that the 3 certain groups and certain Di trips passed, but certain Li failed. To be honest, it is a pity that the interviewer at that time was very satisfied with me if he was the leader of the job after joining the company. , Said let me prepare for the next round, and then received a failed email, called to ask, and finally told me that I still want to recruit people with P7 and above, which is a pity. Finally chose a group of takeaway
Interview preparation
1) This is actually a matter for people. If you are always studying, in fact, you only need to spend a month to review in the end. It is recommended to read more books and read more questions in the group, even if you only read Not speaking, it is very helpful for interviews, because many of them are practical problems, and it is often such problems that can reflect personal ability in interviews. Personally recommend some courses of geek time, you can reuse the fragmented time, and you can learn something by shit. You say this is terrible. The official account should try to follow some good bloggers with good tweets, such as Fei Chao, who pays too much attention to dozens of tweets every day. You are so annoyed that you will read it? A small amount can actually be seen every day to gain something.
If you are usually addicted to work, then theoretical knowledge may need temporary supplements. After all, interviews make rockets. You can look at the articles of big guys. For big guys such as Fei Chao, Yan Ge, Fei Ge, you can classify the articles first, such as spring , redis, mysql, and then record the links after classification, you can click and watch at any time, saving time every time you find, holding this part of the knowledge, at least one side is no problem, because the interviewer on the other side is more food, hahaha. Of course, you can also go to the Internet to find those face-to-face scriptures and the like, and I will show you more than N questions, and you can directly memorize them. Overall, I feel that it is not as good as reading the blog. Anyway, I didn't memorize it.
2) I think the resume will also vary from person to person, because the resume is nothing more than three parts, company, technology stack and project. The company must be very eye-catching, so it's always right to go to a big factory first. Secondly, the technology stack, I think this is the least important, don't believe it?
This is the technology stack I wrote, do you feel that all those who come out of the training class will slap me? That's right, write a lot of bells and whistles, and people will ask if you do not comprehensively prepare, then you will undoubtedly increase the interview Difficulty, so the regular mainstream, basic meeting is enough, these preparations are enough.
The next step is the project. If your project is very frustrated, then you really have to rely on the basics to improve the interviewer’s score. Of course, you can package it very tall, as long as you are round, my impression of the interview is The project is really too important. If the project is relatively high-end and atmospheric, the interviewer will be very interested, and will ask very deeply and meticulously. If you know enough about your project, you can handle it. What? Can't handle it? You can't do well in your own field, so how do you play? Of course, the interviewer will ask some questions. It may be the current problems in your project. You can prepare a few yourself. Sometimes he will ask you to tell yourself if there are any problems with the project. This is the time to show yourself. Show your great foresight, but as an ordinary member of the group, unable to change the thoughts of the bigwigs, make a look like a high aspiration, a hero who is useless, and the interviewer will most likely be fooled by you.
3) Let’s talk about the interview. In this year’s interview, I found that the interviewer was very serious and was taking interview records throughout the entire process. Every question may be detailed. Finally, I will give you an evaluation. This evaluation should be visible to the entire company. Next time you invest in other departments, the hrs of other departments will also be able to see your last interview evaluation, so be more cautious when dealing with large companies. Don't just test the water directly. The interview will be slapped and it may be difficult to make an appointment later. Interviews are generally 3-4 rounds.
The first round is a team member. After you go, you should be equal to you. The skills may be relatively better. The main focus is to investigate the basics. The project will pass by. The main question is the technology stack on your resume. The difficulty is generally not deep. Of course It also depends on luck. There are two interviewers who are very good and asked in depth. Then there is the algorithm. Generally, the first round will not make you difficult to write. Generally, a binary search, singly linked list reversal, and quick sort are more basic. If you can't write this kind of thing, it will give people a very bad impression. Even if you have a good foundation before, after I met a certain group before, the interviewer said very bluntly, afraid that you will be invited to write bugs... Heart, what can I do? , Do I want me to say, if else, crud thief 6, there will be no bugs. . .
The second aspect is basically the leader in your work, such as the team leader. He mainly inspects the project. If the project is really not necessary, he will also ask some basic questions and some practical questions or questions about personal quality. , Finally, I will write an algorithm, the difficulty will be a little higher than the one side, I feel that it may be a medium-difficulty problem on leetCode.
The three sides are the direct leaders of your organizational structure. They focus on projects and personal quality issues. They will also ask questions about career planning and personal development. Personally, they feel that it is not difficult, and there is no need to write algorithms.
There is a question that you will ask every time. You can prepare: Where do you think your system is not well designed, why, and what improvements do you have.
3) A mentality problem. It is normal that the interview does not go well at the beginning. One is nervous and not performing well, and the other may indeed be insufficiently prepared. There is also a situation where your interviewer is a **. I encountered several questions during the interview. The answers I said were quite correct. The interviewer was skeptical, and then I asked him the answer, and he said it himself. I don't understand, and then I leave in unhappy, but in the interview, you say that you are out of breath, and the three-hour journey back and forth is the result. This kind of probability is very small. When the interviewer asks you a question, at least there is an answer mentally, so you can perform normally.
4) The question of interview frequency. I think continuous interviews can really make you enter the state very quickly. You will answer the same questions more and more proficiently and professionally. In the early stage of the interview, you can frantically submit your resume and practice in small companies. I have little time and no alternative. I invest directly in a big company. I am rich in time and have many facets. I have long experience and collect interview questions easily.
5) Fortunately, fate really has such a thing in the interview. It happens that the department you are facing rushes to lower the requirements, and you just go. The algorithm that just happened to be written by you was the one you just watched yesterday. Many of them just happen to be together and you may have passed the interview, so you can help your grandma to cross the road or something.
to sum up
In addition to strength and luck, the interview has to rely on hard work. I was shocked to learn that a group of friends have met more than 40 in 2 weeks. With such perseverance, why not worry about getting the offer you like? I think the company is in the choice of offer. >Project>Salary. Going to a big company will give you a lot of opportunities when you are looking for a job next time. It will also let the interviewer take a high look at you. If the salary gap is not huge, I personally think that you can not consider it first, quote Fei Dynasty quotations , Is there a big boss who has good skills but can't make money? Well, I have said so much, I hope you can gain something. I will join the company next week. If you want to go later, you can ask me to recommend it.
Real interview questions
For the interview questions, everyone must be the most looking forward to it, but I’m sorry that I didn’t sort it out myself, and I don’t have the habit of sorting out the interview questions. I searched a lot of these questions. I don’t think it is very meaningful, but when I write it, I just leave it. Let’s take the next interview question. I thought it was a very good question at the time. It was also a question on the two sides of a group of takeaways I was going to. The question is as follows: a circle, divided into 7 parts, each with the surname, each You can’t repeat it, you can repeat between different copies. Then I will ask you from the first copy, is your last name in this copy, answer yes or no, keep asking the seventh copy, and I can know what your last name is , Ask how many surnames can be put in this circle and still achieve the effect of knowing your surname?
You may not understand it. Let’s give an example. For example, put Zhao Qian Sun Li Zhou Wu Zheng in 1-7, then ask in a circle, you must know what your surname is, because there is only one surname, if I want to put Where is the eighth surname going in? How should I put it so that I can still know your last name after a round of questions? For example, I want to release the king next, 1: Zhao 2: Money: 3 Sun 4: Li 5: Zhou 6: Wu, 7: Zheng/Wang, then when I ask the 7th, if I answer my last name here, you How do I know if I am surnamed Zheng or Wang, so it is unreasonable to put it like this. Based on this idea, you can think about how to put it in order to know whether my surname is Zheng or Wang. Continue to think about how many surnames can I put in to ensure that I will still know what your surname is after I ask around. I'm not talented, I didn't answer it, I just told the interviewer the idea, the interviewer still agrees.
I wish you all find your favorite job as soon as possible. .
