This book covers the most frequent challenge codes included in the final stage of your job interview. The interviewer is looking to evaluate your Problem-solving skills, how you react when faced with unknown problem e.g design an algorithm to solve a problem you haven't seen before. This book is an additional reference so that you can be as prepared as possible.Data structures organize data that algorithms work upon. We follow the following steps to develop a usable algorithm:- Model the problem, identifying the elements of the problem, ending in an abstract data type.- Find an algorithm to solve it, defining the data structures, data types and a sequence of steps algorithms need to do.- Is the algorithm enough fast and fit in memory? Here we must refactor the algorithm possibly changing the data structures and the sequence of steps.- Iterating until we are satisfied.By the end of reading this book, you'll be able to:- understand the basics of common data structures and algorithms and apply them to real questions.- understand the importance of modules, readable variables, hashing, recursion, queues, stacks, and much more.- face with unknown problems better than other candidates.

If you want to join an ever-changing field full of discovery and potential, one where you'll never get bored and have a chance to make an impact - then your answer may be 'yes.' Tech will put you right where the growth and disruption are happening. It will take hard work, but you will thrive if you are willing to adapt and learn. I am a software engineer who faced real interviews as a candidate for startups and big companies. Throughout the years, I have sourced factual questions that have been tried, tested, and commented on step by step and are now part of this book!. I hope you find them practical and useful in your career search. Why are algorithms used in interviews? Jobs in the tech industry are expected to grow exponentially in the next few years. If you plan to enter the job market soon, you must know that companies will evaluate your problem-solving skills based on data structures and algorithms, and you will need to face a complex problem on a blackboard. That's the reason why Algorithms and Data structures are vital. You need this book because it includes the most common questions you can find in a real interview!. By the end of reading this book, you'll be able to: Understand the basics of common data structures and algorithms and apply them to real questions. Apply clean code practices to develop a usable algorithm. Understand the importance of text manipulation methods, lists, recursion, class design, queues, stacks, hashing, trees, graphs, and many more. Develop a complete algorithm using the TDD approach, e.g., graph-based transport system, tic tac toe game. React better than other candidates when faced with a new problem, e.g., design an algorithm to solve a problem you haven't seen before. Understand and practice 40 code challenges explained step by step, including its pictorial representation.

Interviews for software programmers and developers differ from interviews for other types of position in that they consist largely or entirely of coding problems, theory, and brain teasers instead of questions about education, work habits, and experience. There are many books on the latter but none on the former. Thus there's no good way for an applicant to prepare for interviews or to interpret the signals she sends prospective employers by the way she conducts herself during the test. Programmers need to meet challenges of the software interview every time they apply for a job; rarely if ever is someone hired on the basis of having done similar work elsewhere. The software demographic changes jobs with frequency, and understands that remuneration offered for a given position depends in part on how well they acquit themselves when confronted with a poser.· The Job Application Process· Approaches to Programming Problems· Linked Lists· Trees and Graphs· Arrays and Strings· Recursion· Other Programming Topics· Counting, Measuring, and Ordering Puzzles· Graphical and Spatial Puzzles· Knowledge-Based Questions· Non-Technical Questions

This book is about coding interview questions from software and Internet companies. It covers five key factors which determine performance of candidates: (1) the basics of programming languages, data structures and algorithms, (2) approaches to writing code with high quality, (3) tips to solve difficult problems, (4) methods to optimize code, (5) soft skills required in interviews. The basics of languages, algorithms and data structures are discussed as well as questions that explore how to write robust solutions after breaking down problems into manageable pieces. It also includes examples to focus on modeling and creative problem solving. Interview questions from the most popular companies in the IT industry are taken as examples to illustrate the five factors above. Besides solutions, it contains detailed analysis, how interviewers evaluate solutions, as well as why they like or dislike them. The author makes clever use of the fact that interviewees will have limited time to program meaningful solutions which in turn, limits the options an interviewer has. So the author covers those bases. Readers will improve their interview performance after reading this book. It will be beneficial for them even after they get offers, because its topics, such as approaches to analyzing difficult problems, writing robust code and optimizing, are all essential for high-performing coders.

Ace technical interviews with smart preparation Programming Interviews Exposed is the programmer’s ideal first choice for technical interview preparation. Updated to reflect changing techniques and trends, this new fourth edition provides insider guidance on the unique interview process that today's programmers face. Online coding contests are being used to screen candidate pools of thousands, take-home projects have become commonplace, and employers are even evaluating a candidate's public code repositories at GitHub—and with competition becoming increasingly fierce, programmers need to shape themselves into the ideal candidate well in advance of the interview. This book doesn't just give you a collection of questions and answers, it walks you through the process of coming up with the solution so you learn the skills and techniques to shine on whatever problems you’re given. This edition combines a thoroughly revised basis in classic questions involving fundamental data structures and algorithms with problems and step-by-step procedures for new topics including probability, data science, statistics, and machine learning which will help you fully prepare for whatever comes your way. Learn what the interviewer needs to hear to move you forward in the process Adopt an effective approach to phone screens with non-technical recruiters Examine common interview problems and tests with expert explanations Be ready to demonstrate your skills verbally, in contests, on GitHub, and more Technical jobs require the skillset, but you won’t get hired unless you are able to effectively and efficiently demonstrate that skillset under pressure, in competition with hundreds of others with the same background. Programming Interviews Exposed teaches you the interview skills you need to stand out as the best applicant to help you get the job you want.

I wanted to compute 80th term of the Fibonacci series. I wrote the rampant recursive function, int fib(int n){ return (1==n || 2==n) ? 1 : fib(n-1) + fib(n-2); } and waited for the result. I wait… and wait… and wait… With an 8GB RAM and an Intel i5 CPU, why is it taking so long? I terminated the process and tried computing the 40th term. It took about a second. I put a check and was shocked to find that the above recursive function was called 204,668,309 times while computing the 40th term. More than 200 million times? Is it reporting function calls or scam of some government? The Dynamic Programming solution computes 100th Fibonacci term in less than fraction of a second, with a single function call, taking linear time and constant extra memory. A recursive solution, usually, neither pass all test cases in a coding competition, nor does it impress the interviewer in an interview of company like Google, Microsoft, etc. The most difficult questions asked in competitions and interviews, are from dynamic programming. This book takes Dynamic Programming head-on. It first explain the concepts with simple examples and then deep dives into complex DP problems.
