, INTRODUCTION
This book contains basic to expert level Python interview questions that an
interviewer asks. Each question is accompanied with an answer so that you
can prepare for job interview in short time.
We have compiled this list after attending dozens of technical interviews in
top-notch companies like- Google, Facebook, Netflix, Amazon etc.
Often, these questions and concepts are used in our daily programming
work. But these are most helpful when an Interviewer is trying to test your
deep knowledge of Python.
The difficulty rating on these Questions varies from a Fresher level
software programmer to a Senior software programmer.
Once you go through them in the first pass, mark the questions that you
could not answer by yourself. Then, in second pass go through only the
difficult questions.
After going through this book 2-3 times, you will be well prepared to face a
technical interview on Python for an experienced programmer.
