Author side :
You may have noticed something missing here: no impressive of credentials. I
haven't been a professor at a Prestigious University for a quarter-century; neither am I a
top executive at a Silicon Valley giant. In some ways, I'm a student of Technology, just
like you are.
And my experience over the years has shown me that many of the people who
know the most about how technology works also have rather limited success in
explaining what they know in a way that will allow me to understand it. My interests,
and I believe my skills, lie not in being an expert, but an educator, in presenting
complex information in a form that is sensible, digestible and fun to read my books.
"What is real? How do you define real? If you're talking about what you can feel, what
you can smell, what you can taste and see, then real is simply, electrical signals
interpreted by your brain."
‘‘... I am just now beginning to discover the difficulty of expressing one’s ideas on
paper. As long as it consists solely of description it is pretty easy; but where reasoning
comes into play, to make a proper connection, a clearness & a moderate fluency, is to
me, as I have said, a difficulty of which I had no idea ...’’

Please Hold On !
I know many people do not read the preface, But if you really want to crack the coding

single page lines as well. The reason for this, is that this preface has something different
to offer.

complexities for each interview problem, you will find multiple solutions for complex
interview questions. I mentioned approx 2000+ Java Technical Questions and 200+
Non- Technical Questions for before the technical round. This book is world’s Biggest
Java Interview book you ever read.

As a job seeker if you read the complete book with good understanding & seriously, i
am 101% sure you will challenge any Interview & Interviewers (Specially Java) in this
world. and this is the objective of this book. This book contains more than Two
Thousands Technical Java Questions and 200 Non-Technical Questions like before
This book is very much useful for I.T professionals and the students of
Engineering Degree and Masters during their Campus Interview and academic
preparations. If you read as a student preparing for Interview for Computer Science or
Information Technology, the content of this book covers all the required topics in full
details. While writing the book, an intense care has been taken to help students who are
preparing for these kinds of technical interview rounds.
Hello! Now I want to share something important with you. For those of you new to
IT/Technical or any other job interviews, the process can seem overwhelming
Interviewers throw questions at you, expect you to whip up brilliant algorithms or
Program Codes on the spot, and then ask you to write beautiful code on a whiteboard
luckily, everyone else is in the same boat, and you’re already working hard to prepare
Good job! So, throw the ball back in the interviewer’s court.
� As you get ready for your interviews, consider these suggestions:

Always Write your Code on Paper:
Most interviewers won’t give you a computer and will instead expect you to write code
on a whiteboard or on paper To simulate this environment, try answering problems by
writing code on paper first, and then typing them into a computer as-is Whiteboard /
paper coding is a special skill, which can be mastered with constant practice. I mean
suppose your thoughts are interviewer and your mind is compiler. Simple!
First Know Your Resume:
First at all, I want to share something important thing with you that you don’t know. I am
talking about differences! Yes, the Difference between,
A CV (Curriculum Vitae) & Resume. Curriculum Vitae is a document prepared
by the fresher’s or students searching a job. It provides the academic details of the
student, another hand a resume is prepared by the experienced professionals, which
emphasizes job history and on-the-job skills and experience.
While technical skills are extremely important, that’s no reason to neglect your
own resume make sure to prepare yourself to give a quick summary of any project or
job you were involved with.
And Don’t Memorize Solutions:
While this book offers a representative sample of interview questions, there
are still thousands of interview questions out there Memorizing solutions is not a great
use of your time Rather, use this book to explore approaches to problems, to learn new
concepts, and to practice your skills.
So, Talk Out Loud:
Interviewers want to understand how you think and approach problems, so talk
