The first day to do written tests, basic knowledge related to the gauge group, also has a few puzzles, java part was easy (really simple bit of it across the base)
The next day taking resumes in the classroom next door called you, you go to the interview
Side: introduce yourself
1 == and equals the difference
(after A String Object in the equals and rewriting, the answer to the whole thing here)
2 get and post the difference
(here, then answer length limit, not exposed to violence in the url, post relatively safe a little bit of it)
. 3
HTTP request packet structure
(method, url, version, slightly request header field, slightly solid content)
4 to avoid a null pointer
(with caution when slightly equals, for example human to judge if slightly, instead of using toString valueOf slightly)
5 where you want to write a database update statements
(to tell the truth very embarrassed, UPDATE USER SET cid = 2 WHERE ... here is just an example, the interviewer did not ask you to write in detail)
6 Spring characteristics IOC and AOP
(which I will not say)
7 SpringBoot properties
Why 8 redis high
(memory, data structures, single-threaded, the IO multiplexed, non-blocking)
9 JVM tuning
(tune appropriate heap memory, the proportion of each generation of a reasonable allocation, choose the appropriate collection algorithm, using a suitable collector ..ps: Here I am not satisfied with his answer, there are other important points, small partners know reminder)
10 Database Optimization
(optimize table structure, optimize SQL, indexes, and foreign affairs, sub-library sub-table, and so separated from the main backup to read and write)
12 project experience, internship experience, comes to technology
13 asked him what
Notified evening
Two faces
(Changed the director)
1 or before asking project experience to understand the internship experience, the techniques used
2 chat high concurrency and how to resolve the
(ps: before work involves a, say for a moment, and finally talk to the database bottleneck, I said he was not satisfied)
3 so what's asked him
(asked about the company's technology stack, to work overtime issue)
