Two. The questions asked by the interviewer in the algorithm position are summarized as follows:
1、Machine learning & deep learning algorithm interview summary: https://www.jianshu.com/p/4a3c5e34d0f8
Three. The basic questions answered by the interviewer in the algorithm position are:
1、（python）PythonWhat is the difference between “is” and “= =” operation? (ID and value)
Answer website:
（1）Web site 1, where the last question in address 1 is:
-
>>> a = 257
-
>>> b = 257
-
>>> a is b
-
False
-
>>> a = 123
-
>>> b = 123
-
>>> a is b
-
True
Integer is widely used in programs, Python in order to optimize speed.Small integer object pools are used to avoid frequent application and destruction of memory space for integers. Python defines small integers as [-5,256] integer objects that are pre-established and not garbage collected. In a Python program, regardless of whether the integer is in.In which position in LEGB, all integers in this range use the same object. Similarly, a single letter is also like this.
（2）Answer 2
Four, review reading knowledge summary
1、data structure

（4）Summary of interview knowledge — operation system
（5）Summary of the difficulties and difficulties in the operation system interview (strong push!)
5、Probability theory and mathematical statistics
Experience summary of school recruitment algorithm (about 15 or so)
I heard that the price of Chinese cabbage in 17 years’headline algorithm hillock is 30W +, coupled with the previous lab brother said that the development hillock is more serious now, we suggest that we study one, and there is still a period of time for students to pay attention to the algorithm hillock. So, at the same time, I painted dozens of arithmetic posts. The following is a summary.How do they prepare, and leave some of the more classic non-subject background of the algorithmic hand experience for you.
Several algorithmic posts in the hands of SP are basically 985 master’s + subject class origin / non-subject class but the laboratory project is related to or one of them. If there are no job-related projects in the lab or in the non-subject class, then the experience of participating in big data, machine learning-related competitions is more important.Yes!
So if the non-subject class wants to attack the algorithm post, then it needs to lay a good foundation for programming and basic machine learning algorithm, and then participate in some competitions for practice, near the time to find a job, concentrate on brushing more problems, brushing more face, and then early practice.
There are some experiences posted below.
