First round was aptitude followed by a coding test. Aptitude questions were easy. RS Aggarwal will do. Coding questions were from geeks. But never copy code as Scienaptic ppl will actually check each code. If you write well commented code , then you will get an edge in Interviews. After aptitude test 40 were shortlisted and after coding test 12 were shortlisted. Finally there was one technical interview round followed by hr interview. In the technical interview they ask questions like design a snake and ladder game like what all data structures you will use. They ask questions from linked list and trees. Basically if u have covered geeks in a breadth first manner then you can answer these questions. Finally the hr round was just a formality. Scienaptic hr is really cool.
