I work closely with students especially for their placements. This book

aspirants. Indexing is good and easy to understand. Almost all probable
mutations are included in the book. Difficulty level is from easy to

Excellent list of questionnaires. Core Java Interview Questions book
from Vibrant Publishers will be very useful for job aspirants in Java
technology. It includes HR questions too. Many job aspirants are not
clear about the HR round, so it is very nice to have HR questions in the
book. This book will help freshers and junior level aspirants of Java jobs
a lot. My final review is that it will be very helpful for fresher level and
experienced candidates looking for MNC Placements.

Plus, the in-detail explanation along with snippet code examples makes
it more clear and easy to understand.
