Background: Oversea bachlor Math&CS with 1.5yr we in algo trading

Round 1: Prof. Andrew

1. Go through your CV, which market you currently cover?
2. C++ experience, I told him I have 6 year C++ exp, so he asked me have I ever used C++11, and what's its changes to earlier version.
3. Linear Algebra: N by N matrix how many roots in complex space, what is symmetric matrix, and what is positive semi-define
4. More Linear Algebra: {(1,a), (a,1)} abs(a) <1 is it positive semi-define why
5. Time Series, what is AR(2) give the expression, what's it relation to Wiener Process, and what is Wiener Process 
6. Algorithm: give a psudo code for nth power of matrix M.
   Well, first I think I can rewrite M = V^(-1)*D*V (V-eigen vector matrix D-eigenvalues on its main diagonal)
   M^n =  V^(-1)*D^n *V
   He wanted more general solution, since M maybe not diagonalizable. (Hint recursion odd/even)
   Times up when I half finish - he said it's on the right way.
   Confirm to the next round.

Round 2: Prof. Dan

1. Go through your CV from your graduate, why left this firm? (World is so big, I wanna have a look LOL)
2. Career Plan, why MFE 
3. C++ exp. latest use of C++
4. 2^x = x^2 find the roots  2 obvious is one, is there any others. (4), is there any negative roots how many of them? (I got it wrong, only one negative root)
5. Is there any methods to find the negative roots?  (Newton method) , What is Newton Method? How can we derive it? (Taylor) 
6. What is standard normal distr. give the pdf of it. integrate it prove equals to 1 (polar coordinate)
7. Questions
      a. RITC
      b. NY vs Chicago for trading jobs
      c. Is there any other interviews? (ask performance in another way)

Other offers, For question 4 plot the graph you can ez find the answer is 3,  I did not do quite well on this question, made 2 mistakes another was I calculate (2^x)' wrongly

Overall, positive experiences but not sure whether can land an offer.
