Sina interview process

   In fact, I am not satisfied with the current state, because I think six months, although the system architecture is more deep-seated progress, but only a small step. To sum up the interview experience it.
Ready too hasty, and even resume the morning are not prepared, just joined Sina inside, first by the number in front of the front desk waiting for a lot of scared, then later "HR" (Later I learned that developers) give me a call, see after, he began holding a resume to ask me directly and asked a particularly large number, but many did not answer it, let me introduce a bit I think is most proud of a project or would like to introduce the most, and then I it it it (What is the use of social networks and machine learning experts on academic achievement mining what analysis), and then it was mainly around the content written on my resume and asked, basically, and some java cache used, such as in 1.java common data structures list set (type) map (key is what kind of orderly map type, key values in the hashmap is how the comparison for equality), 2. What cache is not used? I used to say that the residual mouth redis (in fact, I learned about this, but not practiced) and ssdb (of this fairly clear), but after I've been asked what redis data structure support, what (at the time my has to take the head sweating) 3. thread the lock and ask what java there are two types of threads, and I answered runnable thread, then asked both What is the difference (Nima, I forgot, although the review before the interview so many times), which is the lock key, what can be modified (classes, objects, what method) (also asked what a lock is how, forgot, I guessed there might be ReentrantLock) Then ask the same three-threaded operating a log file write, how to ensure that it is not confusing (like a long time, I think it is the only guarantee one thread to read and write the log, and then he said, the key is this, then he asked to achieve it then thought for a moment he could not, he later said to be placed in a queue inside, ensure that only one thread reads queue), but also asked whether or not used threadLocal, and then asked how the thread pool to set its upper limit of 4. heavy load and rewrite, ask me how polymorphism is implemented (in fact meant to say it, but the term could not say) 5. memory thread running this time it was the middle of the conference room which accounted for an area in memory, other two people came in, and then the next you ask something about the LBS, such as micro-blog to give you some information, you can analyze out what the location of two people, according to analysis out what the scope of a person's activities          and say let I face another colleague, later learned that a colleague is the leader of this project, very talkative, she has been talking, first of all asked me to learn, okay, then asked the university to learn What course is good? Q. I like the algorithm do? The algorithm how to learn? Design Patterns understand me? I asked for this stage of software engineering, in my experience and understand that what is most important is that I think what is more difficult to place, and then I said yes to learn how a complex problem can analyze simple steps , and outsiders should be different is the ability to find the key point lies, then said, I guess it's pretty short into short out things, so there is this idea, then she said there was a capability is a simple the problem is complicated, then what is to introduce their business, which is the middle of a coincidence I said, before we have to do is this, then she looked down at her I felt like, what then have confidence, said my resume so it is no good or something, so I continue to work hard, 
Also asked me if I quit now, I was worried about how to answer her, she was a call comes in, then pick up the phone, I say let the director to face it, after the director seems to be no interest to me, let me introduce my their most valuable item, and then I come in I can do for them, I feel that I have two questions to ask of a little Mongolian, so very brief answer, stammered, said after a moment of their departments What to do, then asked me why I quit, what year graduated, after what he said I could not answer hesitated, then said the manager quite recognize you, then left
    after just women leaders then came in and asked me Why in the original unit resigned, I guessed might director and what she said, and then said Monday vp interview me (when I do not know what vp is then just answer ah), then let me go back, I now ask there did not resign, I think they should like to have resigned, I said already gone resigned process, she was surprised, and then she asked me if I am biased and also convenient time Is a convenient time for the afternoon, then said, wait until then contact the phone, then I'll do after finishing at the front desk came out.
