If you are looking for a job, you need an interview, and if you have an interview, you can deal with it. The following questions come from the painful interview experience of friends in the industry. Companies that ask these questions include IBM, E*Trade, Siebel, Motorola, SUN, and other large and small companies. There is no reason for the interview, and some of its topics are unreasonable and divorced from reality. Some are written on paper, some take the test in person, and some are asked on the phone. It is estimated that there is very little IDE for you (otherwise you can go buy lottery as soon as possible, maybe). So if you read this article, please don't complain that these problems can be solved by IDE. You must answer these questions accurately under any circumstance. If you answer one or two questions incorrectly during the interview, you will probably be rejected.
Of course, these are the basic questions of Java. Most of those interviewing people will not ask you how advanced Hibernate is. The three components of Eclipse, or the command design pattern, they are all older generations, and they like to ask the basics the most. . Don't underestimate these basics. My friend is first-rate, but because of the problem of basic knowledge, he missed the high salary.
Okay, stop talking nonsense, and get to the point.
So what's the point of me writing this this time? Why not stop and take a look. You can review in a more systematic and methodical manner, and prepare for gold or silver. It has the following purposes:
- It can be reviewed through a system to solve the problem of not knowing where to start, and how to start?
- Establish a systematic review system, where each knowledge point is independent and connected?
- Review and summarize the interview sites of the major factories, and proceed from your own reality to understand the gaps?
Of course, in addition to these there are some very beautiful learning materials, which are very comprehensive and contain 29 knowledge points, from basic to advanced!
