In October, no longer participate in the school recruit, the interview process is really tired, sometimes on-site interview is a few hours. In addition to the pressure of graduation thesis, so did not continue to participate in the company's pen interview. Over the past few months, the review also used to search for information, search the real problem. After all, from small to large exams are textbook review, there are teachers to focus. Now there is no such thing as looking for a job, only by myself. So special understanding of the preparation for the work of the small partners have a good review of the determination, spent a lot of time but did not review how much knowledge, because in the process of searching the information takes a lot of time. And I personally prefer the electronic data, so I am in the form of information in the electronic file storage. To make it easier to view, do a website hosted on GitHub. You can click this address to view: Http://huachao1001.github.io.

It is emphasized here that the contents are from the Internet, and there are inevitably mistakes. Errors are not just errors in words, but they can be interpreted in their own right. Perhaps at this time you may think that most of the content is the blogger casually copy and paste, please rest assured that the content is my own collation, not completely copy and paste, most of which I use their own understanding to re-write the inside of the content is my own review of the information, I can not be responsible for themselves. Just want to let everybody know, do not hold the completely correct attitude to the content inside.

As mentioned earlier, the review information is stored in:http://huachao1001.github.io. Because data is stored on third-party websites, the free tier is used, allowing API visits to 3 million times per month. Therefore, if the current month's traffic is too high, the number of the month is used up, the end of the month may not open. If you have a small partner with Cloud server resources, you can send a private messages to me, I can transfer the data past. The following is a talk about my review of the resources used in the past few months to share with you.
