In early April, I participated in a company's (***) test and interview. The test took 2 hours and took 1.5 hours. The interview was estimated to be more than 2 hours, from noon, leave at half past five P.M...

Make some simple memories...

Pen Test

Original question:There are two main parts: The first part is about algorithm basics; the second part is about image pattern knowledge. The questions are as follows:

① Understanding of pointer Concepts [understanding of concepts. Pointer array, array pointer, pointer to function, pointer function ...]

② Sizeof computing [relatively simple, there are everywhere on the internet ...]

③ Use C Programming to Implement string matching. [This is a little difficult, and the encoding is a little outrageous ...]

④ Using C programming to achieve one-dimensional Maximum Entropy Threshold Segmentation [I need to know the entropy expression. I used this algorithm before the test, but I still have an impression ...]

⑤ The grayscale histogram is drawn in the image pixel table, the image pixel table is re-drawn after the image size transformation, and the image pixel table is drawn after the threshold value. [some basic concepts of the image]

6. In vehicle detection, common algorithms for removing human interference are provided. [I have written several algorithms that I know a little about ..]

7. Use Bayesian's simple operation and classification. [the most basic knowledge in pattern recognition can't be remembered. Fortunately, probability theory is good. I checked it back later. It turned out to be correct, it turns out that Bayesian is just a simple probability calculation. How was it so difficult in class before ?...]

⑧ How to extract features and design classifier for Apple, pineapple, pear, and banana in a colored image [This section describes which Gabor filter is used to extract features that I am familiar, use texture features to extract classification... only after work knows, originally wanted to test the color division correlation only Oh... hey]

 

Face Test

Note: The supervisor is very good. It seems that there is no logic to ask, but it contains almost all common interview questions. The worst part is that you still think you are chatting, there are very few records that can be remembered. The following are some temporary records that may affect your mind.

Content: There are two main aspects. One is to inquire about the practical experience on the resume/Project in detail (with special attention to details, the question is very detailed ); in addition, the questions are roughly as follows (scattered ):

① Development plan for the past two to three years?

② How to deal with the relationship between campus positions/activities and scientific research/Learning (two seemingly different personalities )?

③ Salary requirements?

④ How do I deal with the relationship between my internship and my school study/graduation task?

⑤ What impressed you most?

6. Why did I resign from my original company (indicated on my resume?

7. How to understand responsibility and morality?
