It's going to be job hopping season again , Before that, I interviewed more than ten large Internet companies and got several Offer, After the interview, I felt a lot , Decided to share the first-hand interview materials , Prepare you for similar problems in the future

My main direction now is Java Development is on the way of Architects , Share the problems with you , Also talk about how technical personnel can improve themselves with direction , Be targeted .

1, Baidu

Baidu met twice , Baidu nuomi and financial business department , At present, baidu only has the recruitment positions of these two departments to match me .

The interviews are all in Baidu's new headquarters in xi'erqi , The park is still under construction , It's far from the subway , Need a taxi .

Interviewer's own computer , The whole interview was recorded , First of all, I asked about the structure and work content of the latest work project in detail ,

The interview mainly focuses on the components and middleware technology used in the work to expand , Inspection and mastery .

In algorithm aspect, a simple array local de duplication problem is investigated , It is realized by discarding the tail element of array .

Baidu finance's interview was arranged on Saturday , It should be expanded in various ways recently , Recruitment notices can be found everywhere on various recruitment websites .

One interview was great , Serious attitude , Some questions without thinking will prompt you , Good communication , They were told that they lacked financial payment background ,

But as a new person who has worked for less than three years , I feel Pass The main reason should be the lack of working experience , Educational background is not very bright .

Interview questions :

The next point is Ali's interview

2. Alibaba

Ali's interview was arranged quickly , Two sides of this stop , Two rounds of interviews are on the phone . Listen to my friend Ali's five rounds of interview , Four round Technology HR, Technical interview is a cross interview of several colleagues in the Department , I got to know .

On the one hand, the overall project architecture ,Java Basics ,JVM, Concurrent programming , Database operations , Middleware technology and Dubbo Service governance framework, etc ,

Maybe it's the cloud security department , Half the time JVM, I also asked some questions about compiler optimization ,

Soon after the end of one side, two sides were arranged , Opposite side , More in-depth two-sided problems , The questions are more thorough , Pay more attention to the understanding and grasp of some technical details .

For example, database operation , The interviewer will ask you in detail how the process of inserting and deleting a piece of data in the database is performed at the bottom , The project is configured with read-write separation , It will also discuss the implementation method and underlying logic in depth .

Some questions worth recording :

At present, the social recruitment in Hangzhou is P6 rise , There is a gap between self perception and post requirements , I talked to the interviewer on the phone , No more interviews .

Two interviews , Ali made a good impression on me , Interviewers are big bulls , Day after the interview , Received Ali's email rejection letter , give the thumbs-up .

Most of Ali's positions are in Hangzhou , At the end of the interview, I paid special attention to the cost of living there , At present, the average price of houses in Hangzhou is less than 20000 , Compared with the housing prices in some counties and cities in Zhejiang Province, they are less than 20000 yuan , House prices in Hangzhou should be more normal .

If you get the high salary of several Internet companies such as Alibaba and Netease , It's a lot easier to buy a house and live in Beijing , Decide to settle down again for a while , Two years later P7 Fight again .
