Interview Preparation Tips

Interview preparation tips for other job seekers - I was mainly asked questions based on Java, OS and networking (very basic) in the technical round. But the interviewer was jovial and asked about my hobbies, favorite movies, favorite books (it’s my hobby). He even asked me which one I like Marcel or DC, Cricket or football and a few such questions in the beginning. Due to which I was able to answer all the questions in a stress free manner.

In the HR round, half of the questions were based on basic problem solving that require a bit of out of the box thinking. And, I was asked other basic HR questions like why should Hitachi hire me, Why I am I joining Hitachi and so on.

Both the rounds lasted only for half an hour each.
