such as Tencent, Baidu , Sohu big company like this, must recruit a large number of C language , C + +, Java, Android, and even . net and Php talent.
However, for graduating students who ( even for experienced candidates, because domestic and international top companies basically need written or computer) , the subject of data structures and algorithms , is to give the interviewer first impression of , directly determines your talent is a priority , or reserve personnel .
A few months ago I went to Sina Weibo written test, candidates Java engineer ; I am familiar with the basics of Java , Js, Jsp, S2SH etc. , as well as a year of development or testing experience ;
The first four questions are algorithms written questions, optional two questions , complete with C / C + + or Java; I remember a brief description :
1, there is a one thousand disorder integers, the fastest elect 10 minimum, disable the collection API;
2, please read the following "folder delete recursive algorithm," rewritten as a non- recursive algorithm can take advantage of a collection of API;
3, respectively , please solve the " leap of judgment" "line function body ", " monkey eating peaches ," " Fibonacci series ", " common denominator " four questions .
4, put a few split into a number of perfect squares and can be repeated , but can not contain an example: 42 = 25 +9 +4 +4
behind are some Java -based , Js, understand the three frameworks , design patterns and so on .
algorithms that my scrawl ( 1 small problem with the ring 10 times , 3 small problems do half ; because at that time did not pay attention , I think it does not matter, anyway, I am applying for Java Well , it will copy change, API tone on the line ) , the main job of the back of the subject ; finished papers to pay up , the interviewer looked at me a few questions before I called , " go back to such a message ," he glanced behind Java question did not glance ah !
I did not go Tencent interviewed ( Sina microblogging written all over not, Tencent not even think about ) .
'd have a student go to Amazon interviewed ; when the three sides of the machine indeed tried STL hash table , 1w spot test of random number ah ! He wrote a hash table conflict handling , physical structure , looking almost exactly the same performance , etc. STL , the interviewer said he was " a little bit slow to write programs ," but finally admitted.
want to go to a good company , data structures and algorithms really important ; But Evans , soft , Neusoft , Bo Yan, soft pass and some other small companies, and so it does not matter .
comes my classmates formula: the ability of programmers = API * (DataStructure + Algorithm), are indispensable !
------ Solution ---------------------------------------- ----
is to recruit high -quality , ability to learn fast.
or you say we have to take a few k, but also hard to force overtime every day , the company is not much money , time goes slowly grow , various bureaucratic ethos , culture also lacks meaning rogue tired .
overstating not directly point to 10k or more, high quality , he also easy , everybody efficiency is high , do not rely mix , is not nothing on weekends to drink, nothing to play dota, no ambition , no goals, the damage to the surrounding environment .
called the right people to do the right job.
------ Solution ---------------------------------------- ----
nothing to complain about
Some companies lazy , or for some candidates are not taken seriously , they can fill out a various language questions let you do it.
In addition , the company is certainly recruit junior staff , large companies usually after intake based on individual characteristics of the company and then decide your future direction, so you can now learn java in the company's future is not necessarily dry java
------ Solution ------------------------------------------ -
this problem is more private , I can not tell you, I speak out , afraid you joke, forgive me !
this problem how do you say ?
large companies would prefer to interview Algorithms + Data Structures
University algorithm based on algorithms it is only university that point algorithm theory after learning what really solve practical problems
niche not understand , mainly to determine your ability to think logically it.
But if you then point algorithm theory only show for the University of the words
believe it will not get the offer of
Thus , algorithms, data structures is the foundation , but also the ability to look at your other

today went to attend Tencent side up, by brush, was pretty uncomfortable , I interviewed two people, a mainly C + +, a very good, and he has arranged for me to go to another teacher , asked some knowledge in all aspects , I feel Tencent asked very basic , as Java rarely involved , and Tencent missed the intern , not much to say in this , Tencent hope to interview at least somewhat familiar with the data structure should be .

I was brushed one side , and the interviewer asked a lot of basic questions ( data structures, operating systems, databases, computer networks , Linux , etc. ) also asked a discrete problem . Our class has three sides had people from their answers , I analyzed the reasons for the failure of their own : a written test does not test well .2 first data structure that did not write the program to ( relatively simple, but the interview the former is not ready , the data structure almost forgotten , so ... of course, I might also excuses now trying to learn them ) .3 . selected direction may not be the missing Tencent , one side of the last day of the Pro when to go, people say that the lack of arrangements for web front end and C + + background and technical personnel .
feel second interviewer asked me questions and I answer the change is good, unfortunately . . . . . A question which I'm confused : tcp three-way handshake , assuming it is A and B , the middle of a few lines , I was the answer was three lines , because the book says so , the interviewer said the results counted back and forth a handshake , so I 'm confused , I thought so much of Tencent users , network knowledge is certainly more powerful, did not dare to question , I hope you give me the answer , thank you. Big harvest this interview , interview at least know what to prepare before .
