"Experience" safety post intern candidates

In the school of the first dog for safety post interns of the mentality and feeling, in the endless spit groove process also have their own years of fainting brain memories of part of the application process, I hope to pretend to be a person to the next learning younger brother Learn to provide a point of life guidance ^ (￣︶￣) ^

The story is purely fictitious.

Now think of these times relaxed a lot, at that time in a lot of seniors learn elder sister instigated "three generations, read research ruin life" concept, I resolutely prepared for the grind, is so called I not into hell, who into the hell? Then did not care about the internship, and later looked at everyone in the various delivery resumes, and their own that period of time also back words, is idle nothing to do, so bored to write a resume handed a bit.

Submit your CV

Write a resume naturally need to help first push, here because there is a platform for the technical school has a job version, has graduated seniors can help inside push, no trouble to know seniors, direct resume sent past, and then tragedy
The security post to X company was sent to a head of Java development. Uh, a cramp in my heart.
Then x company directly refused, my resume special is there this time? So far I have not figured out where the problem is! There was no reply to the mail there. To reject the psychological slightly uncomfortable, want to find the seniors at the time of submission has elapsed time, so it is possible to find the seniors help inside push, preferably related departments
Vote Y company over there think can not so casually, at least I also want to take an examination of the person, how can this be brushed off, and then looked for the company over there of the elder at least because the community and the company there have been exchanges , let them help inside push, after rating come out also can, This is even more confusing x brush my resume is what ghost!!!
Later saw Y company's game security began to recruit, alone to submit a resume, with the senior chat will, said it was mid-April interview, let me well prepared (⊙o⊙)

Electric plane

Well, thinking about the electric plane of the April, when it was still more than 20 in March, then it didn't really matter. At the end of a thrilling basketball game, a phone call came in and asked me if I could interview now? At that time the hearts of thousands of gods and beasts whistling past. I said yes, and then started the first round of battered:

Let me introduce myself.
You say you understand the underlying optimization, can you tell me how you found division optimization? How to push to the magic number
That unexpectedly know release and debug, that release can under the breakpoint to debug?
Do you know about the compilation parameters of VS?
Do you know the difference between SEH and veh?
What does Seh look like in the assembly?
What does the Windows exception handling mechanism look like in the assembly?
STL Libraries for C + + you know what?
What does a virtual function look like in the underlying code?
How the subclass inherits the parent class in the underlying
What does the API function look like in disassembly?
What does the import_directory structure look like in PE? What are the important parameters?
What anti-debugging do you know?
What would you do if you were to prevent debugging? Can I strong OD this plug-in detection
Pangolin shell do not know, whether there is a summary
What kinds of hooks, if from the implementation of the way, can be divided into which kinds of
The principle of Detour hook is which of your classification
How does the JMP hook jump address count, and why?
How does CE read the changes in memory data?

And then one side of the technical question I remember so much, when I was wearing shorts and short sleeves on the basketball court for 1.5 hours, plus I wasn't prepared before, uh, being abused all the time.

Later thought kneeling, almost nearly one weeks, the second phone came over, this remember not too clear, at that time with the seniors chatted pretty happy like

What disassembly tools have been used
Reverse a program where you're going to start, what's your train of thought
Flower Instruction Implementation
Double process protection do you understand? What it does and how it's implemented
Single step exception principle in OD
If you want to write a shell, you have to consider which questions
There is a client and server communication, I need to decipher his encryption, where you will start
What is the reason for the getmoudlehandle up and down breakpoints in the pangolin shell?
How is SSDT hook implemented for process protection? And how did he communicate with the user layer?
What are the risks of the kernel layer inline hook?

There are still some problems to remember, it was almost 1 hours.
Then the electric plane ended up like this, and then we talked about ... Well......

Written

Here almost to die, just to remember the online test, in the case of monitoring do not use dual screen, do not lose focus on the current window, do not have the current window is overwritten
Then x company after the written test, I finally found out why my resume was brushed off, but also, which problems are not a few will do, no and Windows-related, and Windows is not related to the reverse, not with the windows underlying related, oh, the direction is wrong ~

Interview one side

There are so many people on the day, line to the outside of a long, oneself at that time burning, dizzy to go to interview, the interviewer asked me what all forgot, is completely subconscious answer, feel here memory lost, finish feeling to kneel, on their own comfort said I also want to grind the party, is to try to see where the gap

Two sides

That night more than 11:40 appearance only received two side of the notice, unexpectedly, at that time to frighten himself not to have a fever, the next day feel good, went to interview

Draw a PE file structure
What does the Windows API function header look like at the bottom?
How does the isdebugpresent bottom come true?
OD int 3, Memory breakpoint, hardware breakpoint principle
Does the Dr Register understand that each of the functions
Use my Computer to monitor this function on the spot.
Use Ida on my computer to navigate to a function
Ida shortcut Keys
Anti-debugging techniques how much do you know?
Go back to give you a software, before 20:00 blasting + algorithm analysis + keygen, analysis sent to me

Did not expect two face unexpectedly have so many actual combat, later the analysis of the software will be sent up, at that time, I have to go to check the course set, there is no time to write the registration machine, the algorithm has a very important function, is a floating-point large number of operations, really did not understand. So the algorithm is actually only part of the analysis.

Three sides

Talk about life, talk about ideals. As long as you do not encounter the more wonderful interview officer There is no big problem, the classmate face Android, was asked to some operational knowledge is also drunk AH

And then just wait for the notice ...

Again, this article is only to talk about their own experience so that the younger generation in the direction of the interview has a general grasp, so that not because of tension and lead to play bad, and no other purpose and meaning.
