Do you know how to attach the debugger to the running process? Have you had prior experience with core dumps?
No1: We kindly ask you to write two classes in C++ and send your code to us. One class shall be a matrix class and one shall be a vector class. Matrices and vectors shall be able to be multiplied. Addition and scalar multiplication shall be supported as well. No linear algebra functions are sought for (e.g. inverse, linear solving, svd etc.). The focus is on correctness, efficiency, and a clean and convincing software design - show us your C++ skills ;-) No 2: You are given a gray scale image which represent the oil distribution in a certain area (pixel value 0: 0 liters of oil, pixel value 255: 255 liters of oil). You can place 64 "drills" in this area. Each drill will extract the oil in a circular area of radius 25 pixels. Please try to find the optimal distribution for the drills, for each of the three images in this archive. Provide your solution as three text files with drill center coordinates, like the example file "drilling_plan_example.txt". You can check out the program "evaluate_plan.py" in this archive. It will be used used to evaluate your solution.
How do you feel about GARCH model? Is it useful?
The phone interview questions were: Various questions about using STL containers and algorithms, C++ theory questions (allocation of memory, references, exceptions, stack unraveling, copy constructors, operator overloading, etc.), Count the number of 0s in an integer, Fibonnacci number (both recursively and iteratively and O(x) of each), write a function that rounds a float to the nearest int.
