Applied through my University. Two telephonic screenings. First one was very easy. All questions are already on Glassdoor like why there is no multiple inheritance in C#. inheritance, polymorphism, encapsulation etc. example of polymorphism. Second round - some more OOPS concepts ...now in depth .... no more definitions.. asked me to write prototype for a class stack.... like function (typename T) void push(T t); etc
Another question related to polymorphism - We have an interface Ianimal with a function eat() and three classes derive from it - Class Tiger, Class jellyfish and class Zebra. All these classes implement eat(). Now we have another class zooKeeper which implements a function feed(). Now using feed() call eat() function. Finally it was the Onsite interview. First round is a one hour test with one question - you have 3 presorted very large arrays. Find the first common element amongst them. No duplicates in each of the array. I gave an answer using hash table and it had a time complexity of O(3n) and space complexity of O(n) but the interviewer wanted a solution in O(n) time and O(1) space. Together we worked the solution and he contributed most to the solution. I would tell you the answer but then this question will no longer remain in the test. The only reason why this question is still on the exam since 2009 is that nobody wrote the answer to it on the web. Rest of the rounds were easy mostly pertaining to my resume and other behavioral questions. And yes you will have to pay for onsite interview expenses yourself. In the last round I was interviewed by a guy with strong accent and he asked me a to right code for binary search. I know it is fairly simple but I messed up as I made a mistake in calculating the mid and that was it when I lost my confidence and started messing up.
Overall the interview was very I easy if I hadn't messed up and lost my confidence and started making mistakes. All interviews will be on board.
