Industry winter, four months, 19 companies, 8 offers, interview experience sharing

The computer test generally has the character evaluation and the written test two parts, the character evaluation is mainly the character test question + reading comprehension + primary school Olympiad + find the rule + chart question, about 30min to complete.

• Failed personality evaluation: Pinduoduo (forgot to do it), Huawei intern (failed and got caught)
• The written test failed :(should be and resume comprehensive evaluation after the feeling does not meet)

• Tp-link: The autumn recruitment will be approved in advance in June, the company has a 985 complex, the interview is basically chat, it is easy to pass, the salary in Beijing is not high, and no overtime pay
• Byte: typical hang and fishing, fishing have hanged, experienced security post resume hanging and hanging, was the advertising department picked up, technical face three rounds + HR face to take offer
• Deeply convinced: I got SSP because of the good luck, one side is water, two sides are normal technical, and three sides are in line with the direction of the project
• China Bank technology: adjusted the telephone surface (touch the bottom), two rounds of technical surface, the things asked are very shallow, the scope is relatively wide
• Nanzi of Guodian.com: It is technical and simple. Offer can be sent in three days. The salary for undergraduates is low and business trips are required
• Baidu: unmanned car department on both sides, voice recognition department three rounds of technology + a round of director face, similar to byte, director draw technology cake
• Huawei (to be arranged) : interns have passed the written test, a round of technical and supervisor interviews, basic chat, but the offer delivery period is long
• Meituan-dianping (to be arranged) : The technical surface of the three rounds is not very difficult. We will not give the results after two months of HR surface. It is estimated that hc is less and the pool is deep

The bottom surface is also the telephone surface of many companies, such as China Bank Technology, Guodian Nanzi, the general time is not very long, about 10-20 minutes, mainly self introduction + project experience introduction, some will have some common basic questions, such as TCP why three handshake. With a certain amount of preparation, the phone will not be hung up. Some companies will skip this step if you do well on your resume or on the written test.

Not all companies have a supervisor face, is generally the department direct recruit or you in front of the interview performance is better, may have SP situation will have a supervisor interview, the general supervisor’s level is higher it shows that your rating is higher.

Head surface will not be constrained by the specific technical problems, after your introduction, head like project for questions, mainly investigate what you have learned project in what they do, and most of the time will be asked some questions related to communicate with people get along with, such as if there is divided between the team members, what will you do on the other hand, Your most memorable project experience is also a common question, which needs to be prepared in advance.

In the supervisor meeting, I will talk more about my experience of student work, leading projects or organizing activities, of course, this kind of experience is best related to technology. Talk to your supervisor about programming specifications, automated testing, software engineering, test-driven development, or project management. Be sure to ask questions. Managers love to talk to new people about this, give them a chance, and act interested.

In fact, I have sorted out a lot of questions I was asked and written down my own answers to some of them (there are still a lot of holes to fill in) during the internship period. In the autumn recruitment period, I felt that everything changed and there were only a few questions, so I didn’t make records. Here’s a list of the most common questions from memory in a few major directions.

• Android Messaging Mechanism
• What does the Android View drawing process do when an instance of a TextView calls setText()
• Optimization upgrade point for Android Dalvik vm and Art VM
• Android screen rendering mechanism
• You know how hotfix works, what kinds of hotfix frameworks you have
• The principle of OkHttp
• Android thread pool implementation principle
• JavaGC mechanism
• HashMap implementation mechanism, how HashMap thread safety
• The realization of reentrant lock, what is the definition of fair lock and non-fair lock?
• You’ve used some of the most common data structures. What do you know about trees?
• Activity startup mode, allowReparent features, and stack affinity
• The WebView optimization
• Experience with Jni
• Have you ever used RxJava?
• Describe your understanding of design patterns. Which design patterns were used in the development process?
• Let me just write it quickly. Do you understand dynamic programming

Prepare a good resume (stepping stone, programmers who don’t pack resumes have to outsource)

Programmer’s resume must be more effort, especially to some of the words should be carefully considered, such as “proficient, familiar, understand” the difference between these three must be clear, otherwise it is in the dig for their own. Of course not. I can give you my resume for your reference. If that’s not enough, here are some resume templates for you to choose from:

Note: You can go to the end of the article to get the resume template and details.

At the same time, in the current situation of so fierce competition, only through continuous learning, improve themselves, to maintain competitiveness.

I share my years of work experience, detailed route of Android architecture, learning materials and a full set of learning videos below. If necessary, you can get it at the end of the article and share it free of charge.
