First, a telephonic interview mostly dealing with algorithms and data structures, in a language of your choice, as mentioned in Resume. My preference was Java. The Interview went on for about 45 mins, it was more like discussion where the interviewer expected you to know how hashtables work, if hashtables are the best data structure for the given situation. Most think it is, but we need to talk about conflicts and conflict resolution. Alternate data structures like trees should be considered. The second round was an online quiz test. Depending upon ur degree, the difficulty of the quiz is determined I believe. Didnt go as I had wanted. Few questions were on data structures, mcqs. Then two coding questions. One was straightforward, required efficient use of a data structure. Second question was unexpectedly on dynamic programming which I was not able to code. Imp - Be very very familiar with the hackerrank environment. They allow you to code in your IDE and you can later copy paste into the browser, but make sure you are properly reading the input. Secondly, make sure you submit the answer, even if its wrong or incomplete.
