I got interview call through eLitmus. Initially they conducted a written test which includes both technical and little apti. Technical is mainly about data structures. The guys with good C language knowledge can crack the writer test. Technical test: (15 Questions) Which sorting algorithm uses divide and conquer policy? Why array elements are stored in sequential memory locations? What of the following sorting algorithm selects the maximum value and replaces it with last element? How many comparisons does bubble sort makes? etc. Apti: (8 Questions) You don't have to worry much about. It is very easy to crack.
