A small group of partners in holding on and hoping heart, voted resume Ali, had little hope, accident received the interview notice ants, this man, is simply "flattered." However, he is better attitude, no matter can finally get the offer, to have the opportunity to interview manufacturers, and others look at the gap, also excellent.
The first round of the electric surface, Duman asked questions based on nothing more than multi-threaded, deadlocks, cache and other issues, the problem is inside each chunk in order to ask, but they are the kind of depth step by step, chain gun We have to ask questions like, until you touch the bottom. Listen also creepy, showing that manufacturers of basic requirements are extremely high, crammed basically pass the test, or rely on the usual accumulation.
The second round is on-site interviews, the rhythm of the top field can be, but asked several questions related to JVM after the answer may be a small partner is not accurate enough, after a few rounds, the interviewer directly go back to such notice, and the small partner to depressed.
I started to think that he was just bad luck, and then after he communicated on the micro letter, he did find limited understanding of the JVM. If a person is limited to the use of the Java language and the Java technology in the framework of ecological functions do realize and do not understand JVM, work on some of the problems encountered in the GC, can not quickly locate and give solutions to the contrary, then, even if the problem GC more difficult to check, you can also have some ideas, step by step investigation, and will not Mangrenmoxiang.
So, you want to upgrade their skills, JVM is necessary to learn, but also manufacturers of a compulsory interview items, from the most basic memory layout, to achieve the advantages and disadvantages of GC algorithms, as well as parameter adjustment of the production environment optimization experience, JVM face through the internet can be seen everywhere, we found a high degree of concern for the JVM.
We are here to share a copy of my own sort of architecture and JVM [GC] tuning PPT, forwarding and attention, then join the group (Java fill the pit road) 789 337 293 to free access to!
