In the Internet to do a few years later, to dachang “gold plating” is the first choice of most people. Big factory not only pay high, welfare is good, more importantly, it is the endorsement of your professional ability, big factory working background how many will give your resume to increase a few points of competitiveness.

But to be honest, it’s not that easy to get into a big factory. One of my friends had undergone more than a dozen interviews before joining Tencent, and finally received an Offer with 40K *16 salary after 4 rounds of technical interviews and 1 round of HR interviews.

The first round focuses on Java basics, such as:

The realization of a hashmap
Garbage collection in Java
What other techniques did you learn besides code, frameworks
How do deadlocks occur
The difference between threads and processes

The second and third rounds focus on the mastery of corresponding technology:

MySQL index, B+ tree nature
Redis persistence
TCP wave four times to explain the process, the last ACK if the client did not receive what to do
For socket programming, what does the accept method do, in what order of three handshakes
The four sides are about the projects I have participated in and my understanding of the business.

If you can’t answer any of these questions, then I suggest you go through the test bank.

In fact, many people do not have a clear plan for themselves, and even do not know what route is suitable for them. In this way, you will be farther and farther away from the desired offer! Whenever you need to have a clear understanding of yourself, do you plan your learning route in advance?

So what’s the point of writing this? Stop and take a look. Can be more systematic, organized to review, prepare for the interview. Have the following purposes:

Can review through a system, do not know where to look, how to start?
Set up a systematic review system where each knowledge point is independent and connected?
Review and summarize the major factories often test the pilot, from their own reality, to understand where the gap?

In addition to these, of course, there are some very beautiful learning materials, summed up very comprehensive, including 29 knowledge points, from the foundation to the advanced have!
