好像大多数人对他家都不感冒,不过希望还是可以帮到某些同学。Application
Support Engineer,选的信号处理和C语言。找工作以来第一次碰到印度人面试,说不能
翻书查电脑没说不可以透题。问题如下
信号处理
1. Nyquist sampling theorem
2. aliasing
3. convolution
4. impulse response
5. FIR vs IIR
5. y(n) = x(n)*x(n-1),是不是causal,linear, time-invariant?why?
6. limit sin(x)/x as x->0 ? why?
7. z-transform, Fourier transform 关系
8. 1,2,3 (t=0),0,1,求Z transform,是否causal?
9. what is PSD?
10. PSD of a white noise signal
数学
11. rank of a matrix
12. nullspace of a matrix
13. singular matrix
14. eigenvalues/eigenvectors
15. derivative; describe it using limits
16. integral with limits of +inf, -inf, 是definite integral还是indefinite
integral
C语言
17. pass by value vs pass by referenc
18. what does "continue" do
19. typedef
20. null pointer
21. malloc
22. #include
Matlab
23. A*B vs A.*B
24. function vs script
25. how to find the no. of elements in a matrix/vector
26. how to cascade two strings in Matlab
27. transpose vs nonconjugate transpose
反正都是本科生级别问题,原定四十分钟面试,只持续了20分钟,感觉全部答对了,不过
按版上说法,印度面试官一切皆有可能。祝大家好运。
