Suppose we have a polynomial f(x) with real coefficients {a0,a1,...,an}of degree n unknown, we could input x and get the output f(x). 1. What is the minimum trials of input to get all coefficients? 2. What if all coefficients are integers? 3. What is all coefficients are positive integers?
I was asked how I would estimate price of stock using history of its price.
Questions are almost exclusively quizzes, brain teasers, some logic, some (fewer than expected) about programming or real science/research, no real opportunity to talk about the daily work/atmosphere etc. Always slightly pushy.
Simulate fair coin with unfair coins
Math problems with data structures and algorithms.
Explain how neural networks and backpropagation work.
several easy brain teasers from a practical quantitative interview book(the most classical green book), some leetcode algorithms(dynamical programming, about easy to medium), best gaming estimation ,and about cv(internship and scientific research at school).
None. Didn't get past the first hackerrank test
Statistics, linear algebra, bachelor level, but still hard if havent touch those topics in years
For example the volum of some strange thing
