How difficult is it for a computer major to enter a major factory for development?
Let's look at a set of online data:
According to statistics, the written test for Internet companies is one of the most difficult hurdles, with an average pass rate of only 10% to 20%. The pass rate of Didi Travel's written test was 18.2%; Tencent's autumn tricks had a written test pass rate of less than 15%; Bytedance had a pass rate of less than 25%...
What you need to know is that even if you finally pass the 50% elimination rate written test, there are Interviews with a 60% elimination rate are waiting for you, and there are several rounds of interviews: one face group face→two face group leader face→three face department manager face→four face director face→five face HR face→offer.
After reading this, I don’t know how many students’ hearts are as cold as the temperature in the northeast.
It is even more difficult for students who are not majoring in computer science.
However, you have to be aware. The crisis of most people is actually your opportunity.
Due to my work, I often contact HR and technical interviewers from major factories. They told me that, in fact, many graduating students with good skills fell into the algorithm interview . However, if you spend more time studying algorithm questions a month or two before the interview, this is not the case.
In fact, you have to do more questions before the interview. Everyone knows this. But the problem is that many people bite the bullet and do it for two weeks, and there is always no effect, so they retreat. There are also some students who didn't study the data structure and algorithm very well when they were in school. The foundation is weak, and now it doesn't help.
In summary, there are actually two points:
- Algorithms and data structures have not been studied well or well, which makes it difficult to make up;
- The problem-solving method is wrong, the idea of solving the problem is wrong, the efficiency is slow, and it is easy to give up.

Record content of 1211 questions, including twin needles, dynamic programming, binary search, greedy algorithm, depth first search, string, recursion, dictionary tree, sorting, linked list and other related topics. The pictures and texts are accompanied by the source code of answering questions.
The questions of the brushing task are summarized according to the type of the question. Eight categories are summarized, and about 5 question types are also summarized under each category to help you break through in different categories, so it will be more focused and more focused. Targeted. If you brush from the beginning to the end, and brush 42 questions in order every week, it is easy to make yourself unable to stick to it and feel very boring. So when making a plan, you can make this plan more "interesting" and targeted, and make it look a little easier to achieve, so that it will be easier to stick to.
