Bytedance will continue to recruit on a large scale, with a demand for more than 12,000 positions on campus this year, according to sources. At Boss, the byte department is also hiring more than 10,000 positions.

And, almost every once in a while, byteDance sees a senior executive jump ship. Tencent’s “Tier-one” recently revealed that two of the five baidu executives who left last year have officially joined ByteDance. In addition, in the fall of the craze, byte also absolutely earn enough eyeballs.

Today, from two aspects to briefly say, I hope to help you

  1. Interview skills
  2. algorithm

But in the past, not many people have been able to answer this question systematically. Most people have some questions like:

The five most common reasons programmers fail interviews

Want to find a high-paying job, learn the solid basic knowledge and professional skill is the most basic, but the interview time will not be able to successfully put oneself also can’t express what they have learned, like the teapot boiled dumplings, don’t come out, the chance of admission will be discounted, how good a job interview is successful? Here are a few reasons why your job interview might fail, as long as you avoid them.

One reason Java programmers fail an interview: You don’t say enough

IT is a common problem in the IT field that programmers are inarticulate. All their expressions of language are replaced by codes. Usually, they can only hear the sound of the keyboard in the office, and there is almost no verbal communication. Especially when the interview is in non-technical link, such as introduction, project introduction, etc., not to knock the code what all can’t come, even the process, the responsibility of the project section, are hard, as a result, the interviewer will think you particularly without passion to work, embarrassed, and the entire interview process also generally impressive, Even worse, so it’s hard to succeed.

Java Programmer Interview failure Reason # 2: Talking too much

This part in addition to the dense type (grandiose type); The ones that get passed are the ones that are too eager to explain themselves; Some programmers after being asked a question (especially the problem yourself don’t know much about will be eager to prove himself, use more words to gloss over his faults, but you should pay attention to the normal to the interviewer technology that than you, or can I ask the question must be a point for this technology is very understand, said the more so the more exposed shortcomings, It is very necessary to master the heat when explaining, I don’t know if you can get to this point;

Java programmer interview failure reason 3: basic knowledge is not solid

Most of the time, especially large enterprise to the requirements of the resume is not particularly high, not necessarily must resume and what can be phase, most of the time, super line Internet companies are the basic knowledge of the master degree, this piece of the most fundamental and most important, many programmers when Internet companies were folded in the interview.

4. Failing to answer the interviewer’s tough questions

The interviewer may give you some urgent questions during the interview and ask you to give a solution. Of course, when faced with such an emergency, it is common to feel nervous and lose your mind, but a mature professional will give a complete solution. After all, this situation is understandable. The most afraid is, can not knock out the simple code, and there is no solution, let alone give a solution. If that happens, the interviewer will have no choice but to say sorry.

5 reasons Java programmers fail in job interviews: Inappropriate behavior

Many famous hundred strong companies, enterprise culture is particularly obvious labels, will be very pay attention to the performance of this piece, don’t say so much, said in a small, even an ordinary man, our own, will also be like polite, civilized behavior, and decent person, also want to be able to more than one such colleagues, work smoothly, the tacit understanding. Don’t shake your legs. Be modest and cautious. Don’t argue with the interviewer.

Today we’re going to address some of these pain points

Java Core

The interviewer is usually able to get a thorough understanding of the knowledge structure of the interviewee in only two hours. If the interviewee is slow and fails to get to the essence of the question, it will be difficult for the interviewee to fully express himself and ultimately affect the interview result. In view of this situation, this book does not explain the knowledge points in a muddle, and strive to simplify, detailed introduction of Java programmers interview is often asked the core knowledge points, after reading can make the interviewer in the interview to give full play to the strength of 120 percent;

The book consists of 9 chapters, each of which covers the following contents:

Due to space reasons can not show all the Java core essence of the friends who need to like this article can see the end of the article can be free to obtain the full PDF version;

The above Java core essence and the following two algorithm books need friends can like this article after the following public account can be free to obtain the full PDF version;

 

Read the advice

The contents of this book are detailed, and it is suggested that readers review the past with the contents as a reference after reading this book, so as to achieve the purpose of mastery. It is recommended that you spend three weeks perusing the book to understand the knowledge points, code and architecture diagrams in detail. Spend another two days to review, recall knowledge points against the catalog, and timely check and fill gaps in the parts that can’t be remembered; Spend an additional three hours of revision before the interview to fully grasp the book. In this way, readers can have a better understanding of the breadth and depth of each knowledge point in the book, and be confident in the interview.

algorithm

Of course, the algorithm is also the most important part of the entry byte, I recommend reading two algorithm books

The first book: “Programmer code Interview Guide: IT Enterprise Algorithm and Data structure problem optimal solution”

There are many good algorithm books, but the Java language to explain the algorithm book seems to be the only good one;

This is a programmer interview bible! In the book, the optimal solution of all kinds of questions in IT famous enterprise code interview is summarized, and the relevant code implementation is provided. In view of the current programmer interview lack of authoritative questions summary of this pain point, this book selects nearly 200 real classic code interview questions, to help programmers prepare for the interview to do foolproof. After “brush” the book, you are “question king”! __eol__ This book uses questions + solutions to organize the content, and the interview questions similar types or similar solutions to the topic as far as possible together, readers in the study of the book is easy to see the connection between the interview questions solution, so that the learning of knowledge to avoid fragmentation. In the book, all the interview questions are divided into four grades, from difficult to easy, so that readers can choose the “brush” questions. All the interview questions included in this book have given the optimal solution explanation and code implementation, and provides some common solution and optimal solution of the running time comparison, so that readers really feel the charm of the optimal solution! __eol__ The topics in this book are comprehensive and classic. More importantly, the book contains a large number of exclusive topics and optimal solution analysis, which are derived from the author’s in-depth thinking over the years. Farmers, are you ready to stand out in the interview of a famous IT company and become famous? This book is the magic weapon you should have. Of course, the book is also of obvious value to programmers who need to improve their skills in areas such as algorithms and data structures.

Book 2: The Joy of Algorithms

After reading this book I and Wang Yi teacher’s idea resonated, look at the picture below;

This book starts from a series of interesting life examples, comprehensively introduces the basic method of constructing algorithm and its wide application, vividly shows the interestingness and practicability of algorithm. The book is divided into two parts. The first part introduces the concept of algorithm, common algorithm structure and implementation methods, and the second part introduces the application of algorithm in various fields, such as physical experiments, computer graphics, digital audio processing and so on. Among them, there are a variety of well-known algorithms, such as neural networks, genetic algorithms, discrete Fourier transform algorithm and various interpolation algorithms, but also the humble sorting and probability calculation algorithm. The explanation is easy to understand without losing depth and rigor, which is of great inspiration to programmers. All the examples in the book are relevant to life, showing the essence of algorithm solving problems incisively and vividly, making you love algorithms and enjoy them.

Write in the last

All enterprises like all-round talents. Only by expanding their technical horizon can they form their own architectural thinking, and their way will be wider and wider.

There is a sentence I think said very right: since the choice of the programmer this line, it is necessary to do at the age of 30 earn enough ordinary workers at the age of 50 earn wages;
