Summary: Alert Enterprise is R&D Organisation. My first interview went close to one hour. Since my primary language was C++ but they demanded for Java, so the interviewer satisfied herself, asking lot of questions from me. Thus I was unable to answer some of questions, mainly which were from Java. I was able to solve all three puzzles. Second round was short and then HR round was very comfortable and there was a casual conversation.

What I observed from the interview experience was that interviewer will confuse you if you have read the concepts recently and didn’t have enough practice, so be very true in interview about what you actually know. They come to hire you, Just give them the reason to hire you.
