30,885 java developer interview questions shared by candidates

First, I had to write 3 test papers which are based on Logical Reasoning, Web- Designer and Java. (Takes less than an hour) I found it easy but my friend didn't pass this round. So it depends person to person. Once I passed the 1st round, 2nd round was a technical interview with their Technical Lead. They start by asking basic questions, especially if you've worked on a particular technology, expect all kinds of questions from there. Open up your Engineering books!! After the second round I met the CEO. He asked straight questions. I felt good after meeting him and then I was offered a position.
