How to use Cracking The Coding Interview Effectively

Gayle shares many tips on how to write better code on a white board in job interview. These tips help to organize code and make writing code on a white board faster and at the same time it helps to avoid careless bugs.

She also talks about the common mistake most candidates did and how to avoid them. Some mistakes might not seem big but it affects your performance later on and it could a red flag in the interviewers eye.

The most important thing is definitely the practice question and solution. I learn a lot more algorithm and optimal way of using data structure by researching into every term mentioned in the solution. You will notice every category of questions has a certain way to approach them. After reading the book and practicing the questions, you will be able to solve most interview questions quick enough that you can use the extra time to optimize your initial solution. If you come up with a more efficient method to solve the problem, then you will be one step closer to landing your dream job.

Common Behavioral Interview Questions

Google has compiled their own list of behavioral interview questions that their hiring managers use in interviews. Lets take a look.

  • Describe your work process for ____. While there are no wrong answers to this question, it can be used to gauge how your experience impacts your day-to-day life as a developer. A good answer dives into your workflow process, tools, and ability to work on a team.
  • Tell me about a time when you took a risk and failed. This question provides insight into how you learn and approach difficulty. A good answer demonstrates honesty and active learning in the face of failure.
  • What is an accomplishment that youre proud of? This question is used for building diverse teams. Google is looking for your specialties, sense of success, and your values in the long term. A good answer looks beyond the accomplishment and prods at what it means about you as a person.
  • What is the most complex thing you know a lot about? Teach me about it. This question looks at your skills, communication skills, and ability to explain complexity to others. A good answer focuses less on information and more on the effectiveness of your teaching style.
  • If you join, how will you impact your team? This question looks at your ability to fit with others in a structure. A good answer shows that you did research on Googles values. Top answers speak to Googles goals.

    Preparing For A Remote Interview

    For phone screens and remote interviews, have a paper and pen or pencil to jot down any notes or diagrams. If you are given a question about trees and graphs, it usually helps if you draw examples of the data structure.

    Use earphones. Make sure you are in a quiet environment. You do not want to be holding a phone in one hand and typing with the other. Try to avoid using speakers. If the feedback is bad, communication is made harder. Having to repeat yourself will just result in the loss of valuable time.

    Practice With Mock Interviews

    The steps mentioned above can be rehearsed over and over again until you have fully internalized them and they become second nature to you. A good way to practice is by partnering with a friend and taking turns to interview each other.

    A great resource for preparing for coding interviews is interviewing.io. This platform provides free and anonymous practice interviews with Google and Facebook engineers, which can lead to real jobs and internships.

    Doing well in mock interviews will unlock the jobs page for candidates, and allow them to book interviews with top companies like Uber, Lyft, Quora, Asana, and more. For those who are new to coding interviews, a demo interview can be viewed on this site. Note that this site requires users to sign in.

    I have used interviewing.io, both as an interviewer and an interviewee. The experience was great. Aline Lerner, the CEO and co-founder of interviewing.io, and her team are passionate about revolutionizing the process for coding interviews and helping candidates improve their interview skills.

    She has also published a number of coding interview-related articles on the interviewing.io blog. I recommend signing up as early as possible with interviewing.io, even though it’s in beta, to increase the likelihood of receiving an invite.

    Coding Platform To Prepare For The Coding Interview

    If you want to practice for the coding interview, you need a coding platform online. Why? First, to find different problems. And second, you can also solve them on the platform and check the accuracy of your solutions. You can refer to Best Coding Platform To Become A Coding Expert for information about different coding platforms. The article lists the different features of the coding platforms available. And it also lists the pros and cons of each platform. You can select the best platform as per your preferences.

    After you have selected the coding platform as per your needs, you need to prepare the coding questions for the interview.

    Picking A Programming Language

    Before anything else, you need to pick a programming language for your algorithmic coding interview.

    Most companies will allow you to code in the language of your choice. The only exception I know is Google. They allow their candidates to pick from only Java, C++, Python, Go or JavaScript.

    For the most part, I recommend using a language that you are extremely familiar with, rather than one that is new to you but that the company uses widely.

    There are some languages that are more suitable than others for coding interviews. Then there are some that you absolutely want to avoid.

    From my experience as an interviewer, most candidates pick Python or Java. Other languages commonly selected include JavaScript, Ruby, and C++. I would absolutely avoid lower-level languages like C or Go, simply because they lack standard library functions and data structures.

    Personally, Python is my de facto choice for coding algorithms during interviews. It is succinct and has a huge library of functions and data structures.

    One of the top reasons I recommend Python is that it uses consistent APIs that operate on different data structures, such as len, for … in … and slicing notation on sequences . Getting the last element in a sequence is arr , and reversing it is simply arr. You can achieve a lot with minimal syntax in Python.

    Not Frequently Updated Enough

    Book Review: Cracking the Coding Interview  Tdd Apps

    Unfortunately there isnt much that can be done about this when it comes to media like CTCI. Its a book that needs new editions every so often.

    Unfortunately a lot of the content in CTCI needs to be updated frequently to change with the landscape. I mentioned that the book is a good primer, however Ive noticed a significant uptick in the last few years in the difficulty of problems amongst large tech companies. Frequently companies are now asking hard style dynamic programming questions even in technical screens as the bar has been raised. That means that easy questions are borderline useless .

    Furthermore, because many of the problems are categorized you have the initial hint of what the problem subject area is, which can give a false sense of confidence. One of the most important areas of practice is actually categorizing the type of problem.

    I have seen a bit of a deviation in some companies in terms of the style of interviews they give. While many of the largest companies still adhere to the straightforward white-boarding style interview, I have seen a significant uptick in pair programming / debugging in a codebase style of interview.

    It would be great to at the very least touch on these other interview formats.

    Whats Inside The Book

    Aside from the obvious 189 questions and answers, there is a lot more content that can further help you. Practicality will tell you that you it would be hard to have actually memorized all the 189 question and answers to ace that interview. However, you do not need to do all that.

    The book provides a walkthrough teaching you how to think about an answer for each question. This should teach you to provide your own answer which does not necessarily have to be exactly the same as the book. Hints are even provided when browsing through the Q& A. To mention the rest of its contents, the book gives 5 strategies when tackling algorithm questions, an insider look on how big companies like Google hire their developers, and techniques to prepare for before finally going to the interview.

    Practical Tips For Coding Questions

    This section dives deep into practical tips for specific topics of algorithms and data structures, which appear frequently in coding questions. Many algorithm questions involve techniques that can be applied to questions of a similar nature.

    The more techniques you have in your arsenal, the greater your chances of passing the interview. For each topic, there is also a list of recommended questions, which is valuable for mastering the core concepts. Some of the questions are only available with a paid subscription to LeetCode, which in my opinion is absolutely worth the money if it lands you a job.
