Cracking the Coding Interview vs. Elements of Programming Interviews: Which One Works Best?
When evaluating candidates for technical positions, the quality of their interview performance often serves as a critical determinant. As a hiring manager, my primary goal is to hire competent and capable individuals who can effectively contribute to our projects. Toward this end, I eschew methods aimed at merely 'cracking the coding interview' and instead focus on assessing genuine technical skills and knowledge.
While many candidates attempt to impress during interviews with a padded resume and a smattering of interview techniques, my bar for success remains high. I seek individuals who possess the specific skills required for our projects, along with any additional skills that would be beneficial. This evaluation often includes a coding test I prepare myself, enabling a hands-on assessment of their abilities.
I have encountered numerous candidates who attempt to present themselves as professional developers based solely on basic knowledge obtained from a class or online course. However, decent preparations or quick fixes do not suffice - candidates must truly be developers to secure a position.
To appreciate the importance of these factors, imagine a typical hiring scenario where a candidate relies heavily on 'cracking' interview techniques (such as memorizing common interview questions or using rehearsed conversation starters). Upon entering the interview room, they might momentarily appear confident, only to falter when asked more in-depth technical questions. Despite their initial confidence, their lack of genuine technical knowledge soon becomes evident.
Analyze the Importance of Genuine Technical Knowledge in Interviews
It is essential to recognize that the foundation of any developer's success lies in their technical skills. Over-reliance on interview techniques without a broad base of knowledge can lead to a disconnect between the interview process and actual job performance. Candidates who demonstrate a deep understanding of programming concepts, algorithms, and problem-solving techniques are more likely to excel in their roles. This is why technical interviews often involve hands-on coding tests and discussions that reveal a candidate's true proficiency.
A popular approach to enhancing one's coding interview skills is through books like 'Cracking the Coding Interview' by Gayle Laakmann McDowell and 'Elements of Programming Interviews' by Adnan Abouttab and Others. Both books offer valuable insights and can significantly bolster a candidate's preparation. However, the choice between these two methods can depend on individual learning styles and goals.
A Closer Look at 'Cracking the Coding Interview'
Cracking the Coding Interview, written by Gayle Laakmann McDowell, is a widely recognized resource for aspiring software engineers. This book provides a structured approach to learning about frequently asked coding questions, algorithmic problem-solving strategies, and technical interview techniques. It is particularly beneficial for candidates preparing for interviews with companies like Google, Microsoft, and Amazon.
The book covers a wide range of topics, including data structures, algorithms, system design, and behavioral questions. It also includes detailed explanations and practical examples, making it an excellent choice for self-study and practice. The comprehensive nature of the book makes it a valuable tool for candidates looking to broadly improve their technical interview skills.
Understanding 'Elements of Programming Interviews'
Elements of Programming Interviews by Adnan Aboutab, Tsung-Hsien Lee, and others is another comprehensive resource aimed at helping candidates prepare for technical interviews. Unlike 'Cracking the Coding Interview', this book focuses more on the process of structuring your answers and providing clear, concise solutions to programming problems. The book emphasizes the importance of logical thinking and structured problem-solving techniques.
It also includes mock interviews and detailed problem breakdowns, helping candidates to articulate their thought processes clearly and effectively. The conversational tone and detailed explanations make it a bit more engaging, particularly for candidates who prefer a more direct and less formulaic approach.
Decision Factors: Personal Learning Style and Interview Format
Personal Learning Style: Both books cater to different learning styles. 'Cracking the Coding Interview' may appeal to candidates who prefer a more detailed and structured approach, while 'Elements of Programming Interviews' is ideal for those who prefer a more conversational and engaged learning experience.
Interview Format: The specific format of the interview can influence which book to choose. If the interview process involves more diverse question types, 'Cracking the Coding Interview' might be more suitable. If the interview focuses more on structured discussions and problem-solving techniques, 'Elements of Programming Interviews' could be a better fit.
Conclusion: The Best Fit for Your Needs
Ultimately, the choice between 'Cracking the Coding Interview' and 'Elements of Programming Interviews' depends on your individual needs and the requirements of the job you are applying for. Both books offer valuable insights and can contribute significantly to your interview preparation. Whether you choose to focus on detailed problem-solving strategies or structured conversation techniques, the key is to ensure that you are thoroughly prepared and demonstrate genuine technical knowledge during the interview process.
Remember, the goal of a coding interview is to evaluate your ability to solve problems, write code, and communicate effectively. By investing time and effort in your preparation, you can enhance your chances of impressing the hiring manager and securing your desired position.
