1、應(yīng)屆畢業(yè)生面試java開發(fā)全紀(jì)錄（This years graduates interview java development record）(written examination did not have to say, but only have no skill, the interview is very important, especially the technical side, I can only say that the most important thing is to relax the mind, I have some important place for

2、 everyone to mark it)First job experienceIt is the first time to write into the workplace, did not expect the first success, seems to be the old saying ah - unlucky in love, career satisfactionWell, the gossip got off and started to get to the pointResumeLet me start with my resume. If Im not mistak

3、en, in April when 28 or 29 of the vote out first resume for the company before, looked at the treatment of 1800+200 performance royalty, or very good (at least in Wuhan, at least there is practice) he said the company is equipped with a special instructor, has finally brought this, another point is

4、that in Optics Valley Software Park, not far from the school (PS: in Hankou and Hanyang than the nearest much). These three points are what I am most concerned about, and why I choose the first resume to vote for this company. After the vote, there was no answer. Oh, my God, Im really crazy. I dont

5、dare to vote again, because Im afraid other people will be upset. Every day in the dry, pain ah brother online after nothing when the double blind, see the echo the key vote resume, according to incomplete statistics, each issued 15 copies of your resume will have a reply, please resume gf. After se

6、eing this, I started throwing around. Although the school has arranged internships, but I still want to find myself, on the one handIs their ability to see in the end is what level, another is to practice themselves in a familiar place, lest finally got to the school schedule, arrange you to a perso

7、n you dont know a friend, relatives are not in place, it is not appropriate, I dont want to go anyway. After this in Wuhan, and then cast 5, and so on for 2 days or no news, really anxious me, and that what, you do not even give the opportunity to ah. Finally, I almost threw all the Java jobs in Wuh

8、an, Shenzhen, all over 22.Wait for an echo22 resumes sent out, but there was no response, Comrades, who can understand my pain (_) 1. write a SQL statement, the output current time, accurate when every minute2. talk about the difference and relationship between ORDER BY and GROUP BYThe third problem

9、 is the most difficult, I rub, I do not directly, there are 3 tables, you need to implement association mapping, the fuck who all remember this code, I generally direct access to COPY,After done to her, she disdain to the sentence, over time, regards your family ah, almost 4 pages of papers, but als

10、o TM I wont give you a whole set of DOTA, the paper made to you, give you 1 days! Then she told me to sit over there and wait for the meeting, and then I passed. I thought I almost knelt, and I didnt do the last big question, and some J2EE didnt make it clear.Technical interviewI sat there for a lon

11、g, plump guy came up to me and say you come with me, then he was taken to a separate room, actually I also dont know he is a technical interview, just think this person is quite familiar.Ill follow my memory and remember how much I say to youHe: Nie. Xiao. Loong。 Well, introduce yourself brieflyMe:

12、Im a big 3 student in software engineering of China University of GeosciencesHe: Big 3?Me: Well, we dont have any classes anymoreHim: how come you dont have classes so early?I have not started 2: professional professional courses, we began on the 1, our school teacher also encourages us to go out to

13、 practice exercises through combat, so there is no class, the last lesson seems to be in April 20 a few numbers, then goneHim: Oh, well, Ill ask you some technical questions(PSs a little nervous.)He: you say, String is a data type?Me: no. String is a final class,Him: Well, then, take a look at this(

14、then I took a pen and drew some numbers on the paper. 1, 2, 2, 3, 3, 5, and I put it all in List. Whats the length of this one?)Me: List implements the Collection interface, and the Collection interface has 2 sub interfaces, List and Set. The Set interface is similar to our collection of high school

15、, no sequence, and can not be repeated. The List interface is sequential and repeatedThe List interface has 2 implementations, one is ArrayList and the other is LinkedList.Him: then you say first, whats the difference between the 2 List and when?Me: ArrayList is the same as an array. It reads quickl

16、y, but it doesnt change very well. LinkedList is the same as the list, faster to change, slow to read. We are doing some small projects, reflecting no difference, out, I usually use ArrayList.Him: what about Map, and HashMap? Whats their relationship? Is it different from List or Set, and is it also

17、 a Collection interface?Me: HashMap is an implementation of Map, Map is an interface, but not a child interface of Collection. The biggest difference between Map and List, Set, is that Map has a key and a value. If you want to load data, you must have a pair of packagesHim: so what are you talking a

18、bout List plus elements?Me: using the append methodHim: what about Map?Me: with add, I am not very clear, use less(and then laughing at each other.)He: what should I pay attention to when rewriting the equal method of Map?Me: and that hashcode has relations, specific is not very clearHe: do you need

19、 to rewrite hashcode?Me: No, its not clearHe: not much, OK, so you say when to call servlets destory () methodI: first through the servlet constructor to create the internship, call init () method, and the 2 step is executed only once, followed by service () methods call doget or dopost, when servle

20、t was reloaded, call destiryHim: Well. The foundation is good. So, whats the difference between GET and POST in submission?Me: for example, when writing a login program, you need to type in username and password, and with GET, you display the values of username and password entered by the user in th

21、e address bar. Post will hideHim: Well, whats the difference between one and the other showing that one is implicit?Me: amount. UnclearHim: Well.Then he took my test paper and turned to the last page, the big question of the database, when I laughed with himHe: SQL is not very familiarMe: Well.Him:

22、thats OK. Ill have more contacts laterI: Well, I think this thing is not necessary to bear grudges clearly, like regular expressions, such as regular I write a validation of the email, I will not be one to write directly to the Internet, drag a OK, no need to remember so muchHe: I and your point of

23、view is not the same as regular I dont remember, but the SQL statement and the SQL statement is not regular, and you belong to the type of Java statement about, you say, your Java syntax, is also dont rememberMe: huh, huh, huh?.He: I tell you a case, I want to achieve user registration, you first an

24、alyze, from which aspects to start writing(for about 5,6 seconds.)Me: first of all, do it on the scoring levelHim: Well.I: first of all to build a model layer, such as Member, there are some private attributes, ID ah, username ah, password ah, and so on, and then generate the corresponding get, set

25、method. After that, build a DAO layer and deal with the databaseFor example, add, delete, here only say user registration, delete will not have, and there is a layer of manager layer, and some people call service layer, but I think the use is not particularly bigHim: why dont you think the service l

26、ayer is of much use?I: because the service layer is transferred inside the DAOImpl, it is possible to do so is to make the system more clear thinking, because DAO is dealing with the database, model is the model class, the two will need a connecting layer. However, in terms of implementation, you ca

27、n also improve functionality without using the service layerHim: Well, whats next?Me: then there is the DAO implementation layer, DAOImpl. There are some concrete implementations.Him: so what do you know about the way you realize it?Me: I know only 2, one is JDBC, and the other is hibernateHe: does

28、hibernate use much?I: do not use much, the teacher did not speak in class, are self-study, and through some small projects to do, which need to use what time to learn, and can not use, it is not very clear.He: class, the teacher is certainly not talking about these application framework.Me: Well, a

29、lot of them are. Im a little bit different. For example, I did a warehouse management system before. The first thing is to do it with MVC. Then learn the SSH framework yourself. You do this thing, and finally to pay ah, although I do backstageBut when you show it to the teacher, the teacher has to l

30、ook at the interface, and then come into contact with the techniques of graphic design of the web. Like what HTML, DIV+CSS, JAVASCRIPT, AJAX, JQUERY, and so on, just understand a bit, not to mention the time to workSome things have never been heard before. I feel strange, it will be difficult to get

31、 startedHim: Well, thats itMe: for example, JavaScript, I will only be a form validation, what users input is not correct, ah, the input is not Chinese characters, two passwords inconsistent ah, and so on. If you need more JavaScript knowledge later, at least I knowThis thing will not feel strange,

32、and will not feel very difficult to learn, and have confidence to learn him wellHim: Well, in the face of our profession, knowledge is exploding, must keep pace with the times, or will be eliminated by the times, do you think you adapt to such a life?I: OK, I think I can adapt to this life, I put th

33、e object into smaller, I feel the results come out, I will have a sense of achievement, even if it is to write a HelloWorld, I also feel that their efforts and hard work has paid off. Not like high schoolIs staring at a college entrance examination, learning English, every day reading, desperately l

34、earning a few months, but the effect is not obvious, I also know that this language class discipline is not so immediate results, then I feel very difficultHe: have you ever thought of taking exams for postgraduate schools?Me: I didnt plan to take an exam. I told you before. I prefer to integrate th

35、e knowledge into the project to study, so that I can learn better. I just read the textbook and I dont have a perceptual knowledge. I dont think it suits meHe: do you have any hobbies?Me: do you play the flute?Him: Yes, musicMe: Well, sometimes it doesnt sound. Ha ha ha!Him: Well, my question is ove

36、r. Do you have anything else to ask?Me: Well, Ill ask you, youve recruited 15 interns, how about the group, or a group?He: almost 4 to 5 people, a small groupI: Im a little worried about is this team, because in the school, not to say that I boast or arrogant what, sometimes a group is more serious

37、differentiation that some basic, what are not, also do not talk to the teamWhat to do is often done by those peopleHim: Well, thats true in college. Strictly speaking, youre not a team, its a groupMe: Well.Him: do you force him to do, or preach him, or do it all yourself, this is the team, you shoul

38、d learn slowlyMe: Oh!He: is there anything else youd like to ask?Me: Well, ask, what do you do?Him: Im backstage with javaWebMe: Oh, so what am I doing now for a technical interview?Him: Well, yesMe: did I count that?Him: what do you think?(2 people laughing at each other)Me: Im not you. If I were y

39、ou, I wouldnt have to interview directlyHe: ha ha, in my interview so many interns, your character is very cheerful kind of, the technology is also in the top, interview you must have passedMe: after? In fact, I still know a little about myself. Take Java said in class, should be considered in the u

40、pper or.He: among the bestMe: Well, about the same, but I know, when I was employed, I certainly would not say that compared with the class, I want to work with so many applicants, than in our class, I feel very serious differentiation. Sometimes when I go out, I see them playing gamesWhen I came ba

41、ck, I was still playing games.Him: Well, it happens a lot of times in college. What pole are you?Me: of course I am good, that one pole, ha ha ha!Him: ha ha ha!Me: actually, I think Im learning very little. I havent studied hard beforeHe: playing the fluteMe: ha ha, that is not, that is, has been pl

42、aying, playing games. Its only after I have experienced something that I really begin to learn. Thats what I learned from this semester.He: what has happened? Is it convenient?Me: if you like to listen to the tragedy, I can still talk to you, if you like to listen to like, then I have no materialHe: Well, dont talk about it first, you go onMe: Well, this semester began to learn, only a few months time, although not very proficient in learning, but also at least know that this technology, and later learn, it will not be very difficult.Him: Well, what do you have?Me: first of all, I took
