Microsoft Software Development Engineer interview questions

3 oncompus interviews. Questions are easy to answer, but I am not familiar with C++ and low level OS stuff, I am strong at Java....Ask me about bit level operations, Math questions and design stuff. No chance to make it onsite. Easy problems include: Given a triangle, output how many edges are of same length. Given a string of only 0s and 1s, find the maximum length of equal number continuous 0s and 1s, such as 111000, 00001111.
