How to prepare yourself to be a Software Engineer at Google?

6 Important Points from a Googler's Perspective.

Before I provide you the list of courses, read Point 1, 2.
Full-time working professionals—Read this answer "selectively" on the basis of your industry experience and academic knowledge.
Pre-University Students—Skip everything and Jump to Point 7.

Point 1: Lets Get to the actual Question i.e.

How can I prepare myself to be a "good" software engineer?

Yep! Rest of the question is optional. Joining Google is not a moonshot. Any Good software Engineer has Good chances to be part of Google work-culture. Problem is how you define "Good".

Point 2: Attitude Adjustment.

Before you impress recruiters at Google, Lets see if a software engineering role at Google is something you actually want.

Software engineering is not as fun as the popular notion says about it. Apart from UI/UX positions, in general, no matter what text editor you use—Eclipse, Vim or Emacs—Your screen will be Black, Boring & Dull. A full-time software engineering role not only requires an ability to work on complex algorithms but enough tolerance and patience to focus on meticulous details of a large program.

At Google, in general, most software engineering role comes down to nothing but mathematics. It doesn't matter how many languages you know or how cool you are with Java, C, C++ etc.

What matters are these four objectives:

Your ability to create efficient algorithm.
Your meticulous skills to read codes written by others and spot issues in it, if any.
Your curiosity to learn and implement new technology trends and adapt with demand.
Last but most important: What you Build, how you Build?

I must point out that attaining these four objectives is not easy. Most of us at Google have hard time reaching these objectives but we try, so should you.

Everyone has different approach towards learning. For me, I read one research paper links I find on Quora(May/May not be related to CS) and one research papers at Google(Internal records)—everyday.

When you join Google, you will have access to all code base, database, forums, research papers and projects which will provide you a great support in learning things which you won't find on Wikipedia...

...but while you are preparing on your way to be at Google, there are few things which are common in the process of learning. In point #5, you will learn more about it—how to reach these four objectives—but before there're some pre-requisites that needs to be looked upon. So, Lets go to next step. i.e.

Point 3: Guide for Technical Development in 2014—From Google.

Having a solid foundation in Computer Science is important in being a successful Software Engineer. Following guide from Google is a suggested path for University students to develop their technical skills academically and non-academically through self paced hands-on learning. You may use the following course guide to determine courses to take but please make sure you are taking courses required for your major or faculty in order to graduate. The online resources provided in this guide are not meant to replace courses available at your University. However, they may help supplement your learning or provide an introduction to the topic. Using this guide:

Please use this guide at your discretion
There may be other things you want to learn or do outside of this guide - go for it!

Point 6: Google Recommended/Sponsored Programs and Groups.

Few Additional Course you may choose to subscribe with respect to your domain or interest. These courses and programs are a great place to learn but they don't increase or decrease your chances to join Google—They are not equivalent to Internship. ( More Info from Robert Love)

  1. Google Course—Making Sense of Data This self-paced, online course is intended for anyone who wants to learn more about how to structure, visualize, and manipulate data

  2. Google Course—BOLD Discovery This two-day interactive conference will provide students between their first and second years of college with an introduction to Google culture and potential careers at the company.

    1. Google Summer of Code Google Summer of Code (GSoC) A global online program offering post-secondary student developers ages 18+ stipends to write code for various open source software projects.
  3. Google Policy Fellowship This program offers students the opportunity to spend the summer working on Internet and technology policy issues at public interest organizations

  4. Google Student Veterans Summit The Google Student Veterans Summit includes a professional development curriculum geared towards veterans' transitions into the workplace.

Point 7: Recommendation for Courses in Mathematics.

(For Pre-University Students)

Personal View: Any attempt to ignore these subjects will put you in the category of average programmers who learn things in completely wrong way.

Staying prepared much before would make coding much more enjoying. There are few pre-requisites, for software-engineering, which you need to understand the core of algorithm. Most mistakes created by software engineers could have been avoided if they would've recalled the simple things from school education.

In your further studies in Maths or Computer Science, You will realize the importance of "Data Structure in your college days" and importance of "Machine Learning in your post-graduate days". So, Following are detailed list of courses you must master in-order to design complex algorithms. For college-graduates, if you had ignored these subject, I highly recommend you should revise it in the best possible way you can.

After you're done with introductory syllabus from your school books, practice the following courses for deeper understanding. Most college students (even working professionals) underestimate the importance of these courses and end up being just another average programmers:

Linear Algebra

Linear Algebra | Mathematics | MIT OpenCourseWare (Recommended by a Googleian)

  1. Coding the Matrix: Linear Algebra Through Computer Science Application (Recommended by another Googleian)

    Learning these will help you understand Regression Model in future—The basic step of Machine Learning. You won't be taught these linear algebra courses in any school, colleges, research labs or institution. Learn it on your own.


  2. Calculus 1 - Ohio State University

  3. Pre-Calculus Courses - Universitat Autonoma de Barcelona

  4. Calculus for Beginners and Artists - MIT

    Statistics & Probability

    1. Statistics One
    2. RNG, Advanced Placement — stattrek.com

Note: By the time you reach college and graduate, the syllabus would've moved towards Machine Learning algorithms. To most college students, mathematics gives them a pretty hard time for first 3 months of Machine Learning courses and by the time they catch up, syllabus moves to more sophisticated areas of ML, such as Deep Learning, Neural Networks & NNSP.

"You won't be taught these linear algebra courses in any school, colleges, research labs or institution. Learn it on your own."

What does this refer to? I thought that Linear Algebra would be a standard course for Math Majors / Engineers? Star Light · 1 year, 11 months ago

Log in to reply

@Star Light well if you go through the link there you will find certain topics like the ones given below which might not be taught at the school or the college level hey are engineering topics somewhat. i would just recommend you to go through the link once and read the syllabus part in it. well the topics about which i mentioned above are :

  1. Orthogonalization (factorization into A = QR)

  2. Properties of determinants (leading to the cofactor formula and the sum over all n! permutations, applications to inv(A) and volume)

  3. Eigenvalues and eigenvectors (diagonalizing A, computing powers A^k and matrix exponentials to solve difference and differential equations)

  4. Symmetric matrices and positive definite matrices (real eigenvalues and orthogonal eigenvectors, tests for x'Ax > 0, applications)

  5. Linear transformations and change of basis (connected to the Singular Value Decomposition - orthonormal bases that diagonalize A)

  6. Linear algebra in engineering (graphs and networks, Markov matrices, Fourier matrix, Fast Fourier Transform, linear programming)
