I started programming in middle school, but when it came time for college I pursued a degree in Economics. My rationale was that there would be too many programmers looking for jobs by the time I graduated.

Boy, I was wrong. Later, I joined the Army to become a programmer, but the recruiter talked me into a military intelligence position, and I spent the next two years studying the Korean language. I served in South Korea for 2 years afterward. Before I left the Army, I attempted to get back into programming and was surprised at the difficulty.

How to: Work at Google — Example Coding/Engineering Interview

I did enjoy making websites, however, but I used software with a Word-like interface that I used to publish my websites. After the Army, I decided to stay in Korea for a year and teach English. A few years ago, I thought I could get hired anywhere. I thought I was hot stuff: the elusive full-stack web developer.

But during my job search inI realized my skills were lacking. I had spent so much time chasing dollars by running startups in my spare time, that I had let my skills atrophy. For years, I had learned just enough to get by.

I could get hired for areas where the tech stack was somewhat outdated, like me. The realization reached its peak last year at a career fair. I was interested in perhaps working for one of the local companies that were startup labs run by venture capital firms. At the beginning ofI decided it was time to make a career change from web developer to software engineer. I would need to study hard and practice in order to compress a computer science degree into a few months, but once I did, I could start a new career.

You may not see web development and software engineering as different positions. Both involve programming and craftsmanship, but software engineering adds to it knowledge of data structures and algorithms, compiled languages, memory considerations, and understanding the impact of coding and architecture decisions on the machines where they reside. Large companies that hire for software engineering positions expect candidates to have this knowledge. I reached out to an acquaintance who works at Google and asked him questions about his experience at the company.

I had been reading How Google Works and was pretty familiar with Google already. This became the basis of my study plan. Google sets a very high bar for hiring. They want to hire only the best. In brief, Google is a company that hires smart, creative people, and treats them well. Google rewards merit, encourages big ideas, and gives employees the freedom to make good decisions for the user. The hiring process is calibrated to bring in smart, passionate people.

Google has honed the recruitment and interview process over the years. The brain teaser questions are long gone. Nowadays candidates are chosen based on coding ability, technical knowledge, and Googleyness. Management is different. They trust engineers to make the right decisions. Trusting employees changes the role of managers at Google from what most folks envision when they think of management. Many of the important management decisions that could be perceived as office politics are handled by a committee to remove that danger.

Read Work Rules! Yes, the benefits are amazing. I went on a tour of the Google office in Kirkland, WA, and it surpassed my expectations.

And my expectations were already high.This is LeetCode's official curated list of Top classic interview questions to help you land your dream job.

Like many other techies out there, Google has been my dream company right from the beginning.

When I cleared the Google interview this time, many of my friends reached out to me for tips and guidance for their upcoming interviews. During these conversations I started identifying patterns and felt like it might be worth documenting these since I know the struggle of interviewing in and out by now. Its a tough process and can get a bit strenuous at times specially if you are working a full time job. A lot of articles on the internet have helped me during my preparation and this is one way of me giving back to the developer community.

Hope this helps! Fun fact, I tried to crack the Google interview once before this in and failed. One interview on that day was so bad that I went completely blank and simply ended up having a discussion with my interviewer :D. Also, later in the article, I have mentioned 1 mistake that I did during my preparation which I wish I could take back. During my 3.

But somewhere in my mind I knew that I had to try because getting into Google was not impossible. Reading about the company and preparing specifically for it is generally the most ignored section by candidates and all I can say is, it is one of those sections that can really set you apart from others.

In my experience, any interview preparation involves mastering 5 important things. Coding, design, language specific concepts, previous projects and resume and last but not the least company specific reading.

All of the companies that I have interviewed for in my career have had at least 2 rounds of pure algorithmic questions where you are given a problem and you need to come up with a solution and code for it. Write code for printing the numbers 1 to 10 on the console. Of course this is just an example :D.

I have elaborated this section specifically in lot more detail in the rest of the article. Depending on the level I was interviewing for, some companies have had 1 round of design questions where you are given a rather abstract system and you are required to come up with a design for that system. If you were to build a social networking website from scratch, how would you design the system?

For the next 3 sections, some companies will have 1 dedicated round for them while some others might combine it with some other sections like coding or design. For most interviews, you are expected to provide the company with a language you are most comfortable with.

You are expected to know the basics of this language in most cases apart from coding ability. Some companies might ask you about the basics while some might just dive deep into one area. What is inheritance in Java? This is one of those sections that I have sometimes completely forgotten to prepare for, since I was completely focused on getting the other sections like coding and design right, but interviewing is not just about coding!
