Infobrain Technologies interview questions

I went through a reference. I am a postgraduate trained on Java technology. I had two technical rounds. 1st round ) : Interview question were so easy from....OOPS Concept(write program for inheritance,constructors, polymorphism),multithreading concept & collection frameworks(Map Interface). In 2nd technical rounds : They asked me more questions from Data Structures...Sorting(only few) & also asked to write program for prime numbers. I didn't remember Wts prime no. But HR gave me clue but could not write the logic. So...I was not shortlisted.

The interview process was swift. The interviewer seemed uninterested . He didn't care for what you were answering . Round 1: java questions / collections / exception / threads . 1 program to be written. Since they basically wanted people for struts , there was a lot of questions in struts framework . All were easy . I seemed to have answered all their questions . They seemed to be okay with it . After waiting for a while they said "HR will give you a call " . After a week no sign of it. Sent couple of mails finally got a message saying "you didn't clear the first round" . They could have said so on that day itself . Totally a waste of time .
