The interviewer first went through my resume and ask about my previous Ph.D. research. Then the interviewer asked me questions on probability theory, wireless channel modeling, and python language.

Pergunta 1
1. Find the variance of X1+X2 given the mean and variance of X1 and X2 when X1 and X2 are independent or uncorrelated
2. If a continuous random variable X has a pdf function fX(x), what is the probability for X=X0, i.e., P(X=X0)
3. If the pdf function fX(x) is a Delta function, can we find the probability P(X=X0)?
4. If a channel impulse h(t) is a delta function \delta(t), what is its frequency response H(f)?
5. What about when h(t) = \delta(t-1)?
6. Say if h(t) = \delta(t) + \delta(t-1), what can we say about the output of this channel? What about its frequency response H(f)?
7. What is the dictionary in python? Any restraints on the dictionary key?
8. How familiar are you with the Object-Oriented Programming
9. Are you familiar with the python virtual environments?

Phone screen - hiring manager was asking about my immigration status, and tone changed immediately. Almost felt unprofessional and discriminatory, I will remember it for a long time to come.
