A company Java interview experience

Why say a company, because the end of the last hanging back also did not remember the company name, is a fellow and friends to push the small company, the name is a bit long, so also did not remember.

The company is really too small, said to be outsourcing companies, and then came back with the ACM before the seniors said, they only said so don't go to face these companies, this is not a price. Then I understand ...

The company is really small, there is no place in the meeting, indeed ah, but the quality of the interview is very high feeling.

My face is a person who wears code jam clothes, and I ask later, he made the match of clothes, it seems to be a very powerful figure, why do you say so, because I did not answer the question how much but because did not do anything to prepare to go, because also did not want to practice so fast, so did not do anything to prepare, And then the Java Foundation is so much less to say.

Asked me the question is quite wide, face Java, HTTP, SQL, MySQL.

The main problems are:

(1) The difference between Hashtable and HashMap, because it has not been used before Hashtable, so of course, this question is not answered ... Back to do the interview problem when found, as if people like to ask this question, in fact very simple ...

(2) What databases are asked, then I said SQL and MySQL, and I asked what my paging SQL statement was, which was a little blurry, because I wrote this SQL statement when I was doing my website, but then I was nervous or something, and I just didn't think it out, and then he told me that SQL is: select top Student where ID in (select Top, from student, StudentID) selects page 11th, and so on; then the MySQL statement is: Select *from student Limit ( M,n); and so on.

(3) asked the HTTP status code meaning, this I only remember a few ...

(4) Then asked a programming question,

namely:map<string,int> map=new map<string,int> ();

The key represents the name, int represents the score, and then let me sort out the score from small to large.

This C + + will certainly, but Java does not prepare, then do not know comparator and comparable functions, and then write to the final need to compare the time will not, so ...

The more important question is these four ways, then did not make out, OK ...

But that is the outsourcing company, when he asked me that HTTP, I only said 404 status code, but he was called out by the boss, and then the other came back to say the company to have experience, and then mean to hang ...

Well, if he's judging by my answer, then I'm not going to say anything about it. But without asking me about my project experience, I just want to say, how did you get this judgment?

But I also did not want to go to this company, forget, is also their own Java Foundation has not reviewed, before the things do not remember, blame me slightly ...

Listen to seniors, directly to face large companies, hang a number of regrets, at least ACM award-winning experience in large companies before a little use, small companies simply do not look at ...

The past few days to fill the Java, and redo almost all the company's face questions, finally can only say a little, leave a memorial.
