background
Master of southwest Shanghai university agronomy of a 985, this science of horticulture, master student of the garden. In addition to undergraduate exam once two (not reading also hung up) than can be said without any programming experience, is a true white. Time undergraduate full of uncertainty about the future, so when graduation exam, students reluctantly go with the flow. Kenji time to see the immediate sister school seniors who have to change jobs, to stay dry design really small, wages do not know, but is not optimistic. So Kenji decided to convert the first semester of the Internet, began learning Java.
About Self
Because the computer science people do not realize, you can only search online posts about a career change. For non-Coban people who, a short time can not expect Coban students a solid foundation, so the main it is to have for learning. Currently the school has recruited mainly on: computer networks, operating systems, databases and data structures and algorithms, sometimes look at some basic commands of Linux.

some advices
- Interviewed US group, Huawei, ZenJoy and multi-network benefits, which are mostly self-introduction after then introduced the project, according to the problem and then ask you introduce the project, as long as the knowledge that you mentioned, you will be asked in detail and also ask some similar to the "how to teamwork, which projects the difficulties encountered, how to solve, learn what" problems. So be very familiar with the project you write your resume.
- After ask some of the basics, here to say, when the self-introduction describes what they are familiar with (such as the familiar java or C ++, mysql or anything else, the framework of which there are familiar, and so, probably after the basics under your self introduction to ask).
- There is to be sincere, do not try to cheat during the interview the interviewer, say what, are not familiar with what they know enough to say, will not directly say not enough, you can own a little package , but do not over-play package off. .
