we applied to high radius through amcat examination. there were 5 rounds and each was an elimination round. the first was a programming round. this is a difficult one there were 2 programs one was related to OS like implement an algorithm on FIFO page replacement algorithm or calculate avg waiting time in SJF etc.. send was a logical question like given two numbers check weather they are in gray code sequence or not etc.. second was a written test it had 10 reasoning and logical questions of average difficulty but confusing. the next was GD on modern topics and followed by a TR and HR. TR was on basic java and J2EE and some on DBMS and C but the questions were tricky. finally there was HR round
