the online skills test had options C/C++/Java. I chose C, tricky questions were on pointers and files. Need to know even macros like __LINE__ . Test had 30 questions and as someone already mentioned, it is similar to a brainbench test with 4 possible answers to each question. 1) o/p of a program containing two two static variables with the same name in a program 2) quick sort function in C (qsort) 3) scope of variables - that has goto and multiple blocks in a program
