Tech Stack I use at Google as a Software Engineer 

Guice vs spring', which one do u think is better for microservice @Neetcode

@@obiwankenobi07 There are public talks about all this. Here it is about piper for instance ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-W71BTkUbdqE.html

Looks like my comments get deleted. Tech stack at my firm is similar too but non-internal tool version of such. No C++ though and Kotlin instead of Java.

you are epic

At Amazon we have a ton of internal tools as well, but they kinda suck, especially when it comes to testing. I'm on a team that owns backend services (Java) and some front end components (React, TypeScript, GraphQL).

hahahaha

😂☠️

Lol

💀

wait until you find out that no one actually inverts binary trees or merges linked lists at work! 😂

Thanks Ted!

No K8s though?

@@michaelasin6050 There should be I think, neetcode just didn't get to explain it, maybe because it's more like infra tools

First one was React.

@@michaelasin6050 We have an internal version called Borg which I guess is public info. Here's the paper on it: static.googleusercontent.com/media/research.google.com/en//pubs/archive/44843.pdf

Have you checked out the internal tech island doc that Urs wrote?

I don't know anything other than DSA and system design. just core java. Do I need to know anything else?? before entering google?? I have interview scheduled. Currently i'm working in networking domain and work is mainly based on C.

@@sharathkumar8338 System Design dude. Make sure you know the in and out of system design

​@@x12624 thank you. i'll make sure i know those things. anything else you would like to suggest? please let me know. I want to make it to FAANG and survive there. My dream.

congrats man

Bazel is Google's Open Source fork of their private tool, Blaze.

The version control is actually a homebrew thing with origins based on Perforce's model. Though there is a Mercurial based compatibility "thing" (more than a shim, but less than a legit full mirrored central hg repo) available, which is probably what you were referencing.

Same in India. Most tech stacks are on Spring MVC/Spring Boot and frontend is on Angular/React. MySQL database with Redshift (AWS), or Snowflake. Apache Spark, Kafka etc.

That's hilarious. C# is the better language though with default arguments, LINQ, and object initializers.

Hi Zhao, I am starting out with java again after 5 years of last using java ever, Any suggestion how should I start, basically I want to reach to expert level but there are too much clutter on web but most resources only teach introductory academic level Java, I dont want to get stuck in Tutorial hell and looking for direction that can help me prepare an Industrial experience on my own. Thanks.

@@sushantbhargav4652 baeldung and jenkov tutorials were clear

Ooof that seems pretty hellish to me. I hate java and OOP in general but still use it

Do you really have to learn all thes languages ? Can I get a decent paying job that only requires you to know one or two languages at the most?

@@jv1192 yes you can and you should stick to 1 language as a beginner, and focus on the Software Development concepts rather than the language itself, once you get enough experience, you will realize that language is just a medium to express your thoughts! I am an Android developer for example and only know JVM based languages (Java/Kotlin)

congrats man

Java doesn't seem like a good thing to use with lambda because don't you have to like start up the jvm every time the function is called?

Is that what causes the cold start issues? Python/JavaScript would be faster?

@@liamconverse8950 For rarely used APIs, Java may not be a good choice because of cold start. But after the instance is 'HOT'... then it is faster than most of other languages. After the first call, the instance stays online for some time, hoping to answer other requests.

Underrated comment right here

They use typescript a ton

Congratulations 😃

Also a great way to make sure the employees have a harder time leaving too.

@@alexandrep4913 I agree. Specifics of internal tools are mostly useless once you’ve left the company

It's time to switch jobs I guess unless you get paid a ton and you intend to retire at that place. I used to do Sharepoint 2010/2013 development prior to going to blockchain development.

They just have their own version that probably does basically the same thing

Ah, thanks I didn't know that

@@NeetCode Piper talk here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-W71BTkUbdqE.html

I mean if you're still using piper at google...

I've been thinking about that, will try to make one this month!

There is a bunch of languages you can use, but it comes down to technical factors a lot. Newer stuff can use rust or (especially) kotlin. Internal tooling or (especially) internal versions of open source stuff with better google integration is SUPER common. I be using go a lot at work, but coworkers even on the same team will have not touched go in a bit

Good to know, thanks for sharing!

Also it requires months to upgrade

Good to know , I used meteor js 2018-2020 . Now it seems mostly dead

yeah why use graphql when you have grpc

@@archmad grpc is an overkill

@@archmad Maybe for BE-FE communication they use GraphQL, but for BE-BE they use gRPC Cmiiw

I bet they're currently working on their own replacement for GraphQL

@@archmad Web browsers don't support gRPC since it operates over HTTP/2. You need to use a HTTP/1 protocol like REST or GraphQL

Java was released in 1995. Golang was released in 2009. It's like saying why use TCP/IP when there is a better internet stack. They use Go, but they have a lot of products that were existent before the release of Go, and would be hard or waste of time to change them.

Actually they coexists in heterogeneous microservice. Java is pretty well in setting-up the framework to manage all the services. And inside each service, the stack can be Java, Go or C++, as long as they follow the same protocol to communicate.

Java is mostly likely used, because majority of senior staff in Google come from Java background. And their existing CI, code quality checks, ... Buch of standardisation tools are well tuned for Java.

Most of the time you're expected to learn new tech as needed. If you're new to c++ for example, it's expected that the code reviewers will have to help you but you also need to learn on your own.

Google uses a version of vscode thats on steroids. Probably similar setup as amazon.

Which publicly available IDEs do you use at Amazon?

The IDE is cloud-based, new version is a fork of VS Code, replacing old version that existed for 15+ years. It encourages Chromebook usage and reduces data exfiltration risk.

Amazon's a big place so things will differ a lot between teams. But I use vanilla PyCharm using the company's license, I know some other engineers in the same org I'm in use VSCode. Setting up an IDE was not part of new hire onboarding.

About 5 years ago, it was pretty much the same at Google, lots of internal build tools and custom extensions for various IDEs (emacs, sublime, vi, etc.) that were popular. There was an internal in-browser IDE that could be used, but it wasn't very good, but good enough for light work (quick-fix) or while using a laptop. But with the pandemic, they had to fix that really quick, and get a proper in-browser IDE, which is now a fork of VSCode. Most people I know, including myself, just never switched back after they got used to this new tool, which was pretty much the only thing you could use while working from home (for security reasons, laptops are just portals to cloud tools, so, an IDE has to be either cloud-based and in-browser, or in a terminal on the other end of an SSH connection to a desktop computer physically plugged into the corp network, like emacs / vi / less). I would add that there was a significant amount of friction between the external IDEs or text editors, even with really good custom plug-ins, and the cloud infrastructure behind the version control and distributed build systems at Google, coupled with the famously huge mono-repo. It was often too easy to click the wrong button or hit the wrong shortcut key combo and send your IDE into a tail-spin, trying to chug through the entire mono-repo or the entire distributed build artifacts.

As a front end developer I don’t necessarily disagree but I would never choose backend over front end. To each their own 👩🏽‍💻

you haven't worked on frontend before in that case. Maintaining the state of the UI, how to achieve routing, how to make the rendering fast by pre-fetching the pages etc are all complicated challenges. Both backend and front-end have their own challenges, so saying business logic happens in backend has no weight since business logic is just one piece. Infra people can argue that infra is better than even business logic portion

@@CODFactory why you’re pressed? 😂 I didn’t argue, I intentionally started my comment with “I personally think…” to chase people like you away. And why would you assume I didn’t work on frontend?! I’ve equally worked on frontend, backend and devops.

@@Aripoma Even I like frontend. Observables and RxJS are too fun to use. Microservices are good as well especially with cloud.

It doesn’t 🤪 Leetcode stuff is only used for interviews and that’s it

thats actually a good point lol

I actually made a video about my resume a few months ago. It actually wasn't very impressive.

at the end of the day it's more important that you have the ability to learn quickly as well as think before doing.

It's definitely used a decent amount, but a lot less than Java or c++, mostly cause of legacy systems

Don’t solely rely on google but the opportunity to work in the industry should be the dream; google is just an additional bonus

@@friction5001 Some people have preferences in companies as they love the stack those companies use or they love their products, so they want to work on them.

Don't put any company in some pedestal. I say this as someone who is also a software engineer in a tech firm. It's all the same job everywhere. Work for a company that pays you well and has a great team. Google has been known in recent years to pay less than the rest of the market and isn't as preferred among many veteran engineers. Sometimes paying less by over 6 figures just for the name. Same happened to Blizzard in past. Put a company in some pedestal and companies take advantage of its workers. But give a try for sure. Great company to relax at.

@@2RosarioVampire So what are the companies that you suggest?

@@reviews9216 In this economy? Any company that accepts you. Most of tech firms are laying off/freezing overall.

Pretty sure it’s internal

OMG are you serious. I’m doing interview prep right now because I was hoping to interview with them 😩

I have heard about slow hiring there recently, didn't believe at first but looks real now after reading your comment

@@Aripoma I would say if you’re in the middle of the process just go through with it, they keep your interview scores for a year + a little prep never hurt anyone 🤞

Thanks @@hello1000ize do you have any tips on your preparation? I’m doing leetcode every day and trying to learn the patterns. Where you part of any discords/groups that helped

@@hello1000ize Loving your positivity! You’ll definitely succeed, all in a matter of time :)

I think it depends on the team. Generally, they use C++, Go, Python, and Java. And I assume they build their own frameworks.

Git is used, quite a lot, just not for the core stuff. Like, all of Android, Chrome, ChromeOS, etc is on git.

"Google knows what they are doing", Really? "Google+", "Sites", "Hangout"... Maybe google know, but users don't!

Google uses a monorepo, where (almost) all code across the company is stored in one repository. Branching isn't used, so everyone is developing against HEAD. It sounds crazy (it did to me when I first joined), but it works incredibly well. It means that if I write a library which other teams use, there is only ever one version of it. I don't have to worry about them using an old version of my library. I can make breaking changes to my library by updating all of the existing uses of it, since I can easily find all references to my code. I don't have to leave around deprecated functions in case someone somewhere *might* use it.

@@haxney So how to do actions like revert, decide when everyone is done and changes are ready for review or ready for release etc?

What in the absolute fuck?
