The process took 1 day. I interviewed at MathWorks in Mar 2012
Interview
Asked about basic computer science and discrete math concepts as well as about specific constructs of the Java language. Asked about data structures, static classes and methods, sorting algorithms, big o notation, trees, lists and double to int conversions. It was really hard to understand the interviewer over the phone due to his thick accent.
Interview questions [1]
Question 1
Are a binary tree and a directed graph the same thing?
