After the second interview in the afternoon, I felt cold, and sent a gluten to the interview to save my character. . .
In early March, I asked Baidu, which was pushed by the seniors, and it is reasonable to say that it is the background development of PHP, but don't ask me why there is no PHP question =. =
One side, mid-March, 29 minutes
1. Project
2. New and malloc, delete and free
3. Four types of conversion in C++
4. Two 500G (large) files, how to find all the same lines in them, the length of the lines is not fixed
5. What are the implementation methods of Hash
6. Hash conflict resolution
7. How is Stl map implemented, why use red-black tree instead of hash (bewildered by the question...)
8. What command should I use to view a 100G file in Linux
9. The principle of cat
10. How to troubleshoot the high usage of Linux user mode
11. When will I graduate and when will I be able to do an internship?
I didn't answer the following linux questions, and I didn't even understand the tenth question. . . .
After one side, the senior helped me to ask and said that I had passed, and then for various reasons, they pigeoned me to the present =. =
Two sides, 4.13, 34 minutes
1. Project
2. DNS resolution process (to the depths of the soul)
3. TCP three-way handshake and four waves
4. TCP retransmission (to the depths of the soul)
5. What course is your university most interested in? If you were asked to introduce this course to a non-major classmate, how would you introduce it?
6. User feedback xx business (such as payment) is too slow, how to troubleshoot
7. What do you know about operation and maintenance (the internal promotion department is the operation and maintenance department)
8. When can I come for the internship, how long is the internship, and are there any requirements for the location?
9. What do you want to ask me
2 and 4 really go deep into the soul. . . Originally, I only knew the state of these two, and then I was dug so deeply, and the answer was very poor. . . So I feel cold after I finish it. . .
So far, there is still no offer, and I feel like a spicy chicken. . .
