Preface
These topics are the ones that netizens were asked in interviews with first-line Internet companies such as Baidu, Xiaomi, LeTV, Meituan, 58, Cheetah, 360, Sina, and Sohu.
Familiarity with the knowledge points listed in this article will greatly increase the chance of passing the first two rounds of technical interviews.
Frontline company employees and netizens are welcome to submit the interview question bank and leave a message.
The information on the Internet is divided according to the company. It is a bit difficult to find specific knowledge points. I will sort them out according to the knowledge points and see which ones can be found quickly.
Xiaojiatou’s resume started on July 12, and he invested in about a dozen companies. The first was JD. However, he did not give an interview. Later, he did a written test and did not get an interview with JD.com. The first one is the deep conviction network, which basically asks both sides, and the network is not good, so there is no more text. For the written test, I have done several companies, Pinduoduoliang, Cvte cool, and Duoyi Internet cool. Shell and Youdao were the first to give interview opportunities.
On August 25, Shell Beijing live. The on-site interview experience is a super large room, where a bunch of people interviewed. It took about 40 minutes on one side, and waited for an hour after the face, 30 minutes on the second face, and soon after the second face. Shell gave me the feeling that it is very efficient. I will know the result of the interview on August 30, and the reimbursement will arrive soon.
Basically, I didn’t submit my resume since mid-July. There were more than a dozen companies from mid-July to August. Kuaishou and SF Express were directly brushed, and later written exams were not given a chance. Baidu voted for the written test in September, but there is still no news, and the status shows that the written test passed. Ali and Tencent didn’t dare to vote at the beginning. After all, they knew they were very good. They voted too late. Tencent didn’t give the interview opportunity. Ali asked about the basics of CS. It can be said that I asked what I learned at university, and there was no future Text. I voted for Toutiao and Meituan. Didi started late and didn't pay attention. Toutiao and Meituan got the offer, and I feel they lack Android.
But one thing to pay attention to is that when the interviewer asks you questions, there should be no traces of memorization, and more thinking and understanding of your own, such as a common interview question: talk about java abstract classes and interfaces. Of course, it’s not very good, but to give the interviewer your own thinking process, Xiaojia usually answers like this: Abstract classes are actually very similar to ordinary classes, but with an abstract modification, they can have abstract methods; and interfaces It is not the same. Its design philosophy is to complete a certain function or define a specification, so it has only public methods and no member variables, balaba. It would be better to make a difference than item items.
The knowledge module of Android is mainly divided into several parts: javase basis, java virtual machine (you can learn about the virtual machine on Android by the way), java multithreading, Android basis, open source framework, computer network (mainly TCP/IP, HTTP, HTTPS) ), and then there are very important algorithms and data structures.
The last thing to mention is to prepare for autumn recruitment as soon as possible, pay more attention to recruitment trends, and invest as early as possible.
At last
