A few days ago to the interview, the candidates did not think a low-paid intern, has written, twelve chicken thief child simple questions, because I usually focus on doing those bells and whistles, nice demo of the game, not many books read , literally a brain fever, answer them nothing, after looking at a title, giant fucking regret. U3d recruit training is now only 7-8 at home, next door java 70,80 home, alas, really bad mix.
1. Static method which does not allow any static member, replacing the parent class subclasses casts may not be required. (Daily mouth hung a critical time just do not know what to think)
2. Logical Bitwise.
- We need to know binary decimal turn knowledge
- Decimal turn any number, as long as in the number of continuous write the remainder out just fine, first write on the far right, the last one written in the leftmost
- It may be first converted to hexadecimal, to facilitate the conversion to a binary
- Left logic, mobile number k to cancel the number k from the left, the right complement of k 0
- Logic right and left opposite logic on the line
- Arithmetic right into the 0s complement (k most significant bits of the value of) the leftmost
- In the c language, logic and right are unsigned, signed is the right count, java >> where is the arithmetic, logic is >>>
- See in-depth understanding of computer systems inside, in addition to the pointer, complement, anti-code, the use of bit-level operations in the mask operation is too complicated, do not look
3. The remaining questions are LeetCode, which prove safety Offer algorithm problem.
The entire process in addition to basic computer algorithms and data structures, not asked a little knowledge about Unity, I still face questions online to see what other people who posted: difference coroutine and thread? People simply do not care, alas, the final sentiment: self-year Unity, not as self-study data structures and algorithms of the year. People simply do not care about your Unity to learn how.
