f*****y 发帖数: 444 | 1 phone interview with hiring manager & hw engineer - 1 hour
1. brief introduction of company
2. resume questions
3. Difference between i2C and SPI bus? CAN bus?
4. what is size of char, char*, void*, int?
5. What debugger tools do you use? Are you familiar with ICE?
6. Node a and b has resistor r1 and node b has resistor r2 to ground.
Node a have Va, what is Vb? why use this circuit? if exchange r2 to a
capacitor, what circuit is this? can this circuit be implemented by software
and how?
7. how do you drive LED? and how do you change brightness?
on-site (C language)
1. why leave company? and lots of behavior questions
2. set and clear bit 2
3. define a macro and tell precautions of macro
4. difference between macro and typedef
5. tell the meaning of char const, const char, char * const, pointer to
functions etc.
6. int x=3,y=2; x+++y; what is result of x and y?
7. meaning of volatile keyword? What's wrong with
int f(volatile int *x) { return *x * *x; }
8. what's wrong with following interrupt service routine?
void isr(float x) { ...; printf("%f", x); }
9. what is the output
int a=-20;
unsigned int b=6;
printf("%d", a+b);
10. what does static mean?
On-site is simpler than I thought, but it focus on basics. No tricky
algorithm problems. |

s*****y 发帖数: 897 | 7 Qualcomm? Sounds very like their interview.
【在 f*****y 的大作中提到】 : 没有,电话面试没法画。

f*****y 发帖数: 444 | 8 6个小时呢,只有一个人问编程一个小时, #7,#8是我印象深刻的题目,其余不重要的有些已经忘了。大量常见的behavior 问题, 懒得贴了。还有就是参观,吃饭,聊天。
只有一个人问技术,让我觉得有点奇怪说实话,况且面试是安排在4/1 !
赞一下那个考技术的,把气氛搞得很轻松,还经常有提示。 |

f*****y 发帖数: 444 | 15 actually it may not be the best practice.
say signal y=x*x
the first read *x and second read *x may be different. So it's better to
have a variable to save it t=*x; return t*t;

s****n 发帖数: 786 | 17 现在工作机会多吗?嵌入式的要求又广且杂,pay的真是不怎么样。
你这个面试算比较轻松的,起码专业问题都没问。
