Record my magical experience of getting a NetEase game offer: I don't know where I saw that NetEase Games is recruiting data mining interns, so I submitted my resume with the mentality of giving it a try. Of course, in my opinion, it should be able to pass the resume screening. of. When I received the written test notification, I was very nervous at that time, because the previous written test was abused by Vipshop, mainly because I didn't remember one SQL question and one function, all the SQL questions were GG, and then I filled it up, including the common ten Big data mining algorithms and SQL. Then went to the written test (Tuesday).
(When I saw the title, I was still very thankful, because I knew all the first three questions).
The content of the written test has four questions, each with 25 points; the first question is SVM, and the test site includes the common uses, principles and kernel functions of SVM;
The second question is an SQL question. Two tables are given. The inspection points include query and aggregation. The last question examines select, distinct, left join, where, group by, order by desc, having, and limit.
The third question is about LR, the principle of LR, using LR to predict the loss of game users, what is the correct rate, what is the recall rate, and give an example to calculate these two rates.
The fourth question is scary, it seems that I basically didn't do it, three small questions; the first one is how to describe a game player (that is, what tag attributes to use to describe this player), the second question is to use the star model to Draw the relationship of the first question (I remember that it was mentioned in the data warehouse in the data mining principle), and the third question is to deploy the code on mapreduce to do a calculation.
On the way back to school, I thought about the last question of being abused, and then I thought about it later, maybe others wouldn't do it? !
