Code With Me: 24 FAANG Interview Questions

Get your daily dose of FAANG for 24 days, or one mega-dose of FAANG for one day. This video is mostly designed for guided practice. That means, if you're trying to get good at coding interviews, you'll get the most out of this video by trying the questions yourself and using this video as a guide if you're stuck or want an alternate solution.
But if you want to watch this video for other reasons... go ahead, too.

The most valuable part for me is when I see you make a mistake or don’t know what’s the problem were, and this makes who watches actually realise that making mistakes or not knowing what to do is actually good for them and for their improvement, and don’t have to go just typing mechanically like they do in movies. And your planning also is awesome

[@alexliebhaber3109]

Hey Colin, I'm a web dev atm. I've found your channel about a week ago, and watching your videos has me wanting to go deeper into data structures. I appreciate the content!

[@kdot78]

[@tedchirvasiu]

Holy guacamole, 4 hours of content

[@CostaKazistov]

Breezed through it in under 4 hours. Wow. You'd be making well over six figures in a FAANG company. It's nice that you are enjoying teaching. Thousands of coders here on KZbin are benefitting by learning how you approach solving these questions.

[@zecrumpet9984]

Not true. While he's an amazing LCer and CPer, that will only get you so far. You need to have excellent communication skills, design skills, and domain knowledge to be able to make it past six figures, and even past 500k at most faang companies. Not to say Colin Galen doesn't necessarily have these, but I just wanted to mention that you cannot have only one of these skills above and achieve what was mentioned.

[@MrTacoMan123]

@@zecrumpet9984 this is true. I had a competitive programmer in my team and he was a low performer. Couldn’t do anything else well besides coding and eventually he got laid off

[@YeetYeetYe]

@@zecrumpet9984 Most likely by "well over six figures" he just meant "well over 100k". It's hard to make millions, even at FAANG. You need to be at the Principal Engineer / Staff Engineer level for that, which extremely few people ever get to.

[@michelangelopus2051]

You actually do one hell of a job explaining the logic behind your code. This is a great code along experience and really lets others follow your line of thought. Please keep these type of contents coming!

[@horizon204]

This content is way more helpful than competitive programming since it benefits lots of people. I have learned a lot merely from your thinking process. Keep up the good work, wish your channel would grow

[@dhankaniaryannarendra8504]

LOVE UR VIDEOS KEEP THEM COMING. IT's an honor to learn from the best in the field.

[@tedfitzpatrickyt]

This is awesome Colin, I’ll be coding along with your video soon.

[@retrograder3303]

This video is really useful for interview prep! Shows what you should be thinking about

[@ranitbandyopadhyay]

Want this sort of videos regularly. Keep it up 👍👍. By the way 3rd problem can also be done using bit manipulation and this optimises the space complexity using xor

[@verified_tinker1818]

There's a fiendishly simple solution to "Rotate String": create a string that's `s` repeated twice and check if it contains `goal`. It'll contain every possible shift.

[@ethanmky3179]

L😊p😊

[@isws]

sure, but you again, have to do some rolling hash or some other pattern finding algorithm if want to have a O(N) solution. Otherwise you are gonna end up to a O(N^2) solution, which is good enough when N

[@akashsonar6332]

I have never even though of that.

[@TRoss-ru6sg]

I love this style of videos Colin

[@derilraju2106]

we need more of these!

[@Daman1628]

keep doing it, you are a godsend

[@Ramon01]

amazing how you came up and implemented that bit manipulation at 1:24:00 ! I would have never thought of that!

[@vincevdam]

I just hope to get as good as you someday. Thanks for this video.

[@ritwik121]

Thanks for these leetcode series.

[@mkd0x]

Hey colin Love your channel, I love your content and especially your mindset videos. I feel like proper mindset and discipline are the #1 element of success. And sometime in the midst of all the fake motivationnal videos, it gets harder and harder to have a proper base to lean on. I learned a lot from your video on the "Dark side of competitive programming", the difference Beetween Growth and Fixed mindset. It's not that I didn't knew it, but sometimes having a stranger speak vocally about your inner thought helps realize stuff you already knew, but it an effective way. Keep up the video when you feel like it, you're awesome man !

[@badarmiqdad3161]

As a competitive programmer,if you were to begin from the start what would you change about the learning process?

[@Loev06]

With the problem at 19:37, could you also have calculated the sum of the values of the characters? The difference between these sums will then be the added character's value.

[@akshaygulabrao4423]

no time complexity benefit, so counting is simpler and more readable. but your approach does work

[@TrollFreeInternet]

Thank you for uploading this..just one suggestion..it would be nice if you can explain time and space complexity at the end.

[@codingmaster008]

you should( explore mi and al datascience and ) do projects and system design for interview Great job colin.....

[@imbesrs]

youre going crazy thanks for these videos!

[@mostpplareslaves]

left my pc for 2,5 hours and this is what I come home to?! .... gj AI

[@aviral4080]

hey colin, pls bring back topicwise stream ! Thank you

[@elvisgarcia1822]

Hello Colin from Dominican Republic. if you get change can you make a video of how to get stared in competitive programing for people who doesn't know nothing about algorithms and data structures like vlogs to read, if any kind of mathematics helps idk? I'm personally learning about web development but when I try to learn algorithms I don't undertand almost nothing like how to analise the problem or start to solve the problem, I don''t know what to do :( I'm so impresed about your skills and how fast you analise the problem and solve it, thanks god i found your channel, i really apreciate your content :)

[@kratos1537]

Thanks

[@andee2]

what a legend

[@_sixtyfour]

how long did this video take to upload? nearly 4 hours of video to compress XD

[@AsherDMckoy]

My guy needs to get his hands on Jane Street questions

[@crazycow08]

it's simpler to use auto to represent whatever this type is in the for loop.

@colin what drawing pad do you use

[@sinocchi3321]

26:54 wonder how it still works when your bool_all_9 and all_9 are different variables

[@lel0uchfr199]

Hi, I’m new to your channel and I love the whey you explain, I have a little question, what do you think about codewars ? And could you do some JavaScript sometimes or you only know to do C++ and python ?

[@TannerJarring]

no one cares

[@johnapple3471]

YO that last question! This mfker is a genius

[@xskrish]

finally done with that thumbnail as promised

[@theblinkingbrownie4654]

1:40:00 counting characters should be faster, right?

[@russellc]

Blind 75 next ??? 🙏

[@CostaKazistov]

It would be like that video of William Lin speed running CSES questions in 12 hours (most of which are equivalent of Hard level on Leetcode)

[@jonathanjoestar176]

should it be updated to MAANG bc fb is Meta now? x)

[@CostaKazistov]

Goodbye, FAANG. Hello, MAMAA. [last one: Alphabet]

[@jackgame8841]

could u make it run on console, i'm really curious how this is work 8:35

[@shivanshkhare5943]

In google hard, you didn't even think whether there would be a way to not remove an obstacle so that we could remove another obstacle later and reach the end faster. And then come to the realisation that not removing it is already covered by the different path in the bfs we are doing. You just knew the answer. The above logic was like done internally by your brain. You didn't need to consciously think about it. Thats really weird. I have never been able to do such a thing in any skill. Maybe I just never practiced enough.

[@johnapple3471]

Bro this guy probably is rank god on LOL

[@teddy911]

are you in college or ?

[@gamedime8450]

Why this video keeps getting recommended to me?

Yeeyeee...

[@marcgrab]

I guess if you switched to python you could have finished everything in half the time. :)

[@AndrewErwin73]

I appreciate that there is a world of competitive interview questions...but the fact is, most of this stuff is useless if you are a web developer. Back in my day, we asked things like "what is the difference between a class and an object?", and "what is an interface? how does it differ from an abstract class?" and "what is the different between an inner join and a left outer join?"...things you might actually need to know when building a SaaS application!

[@suraj-ej6oq]

Please share code in java also.. Please...

[@amitmahato6404]

Understand the logic. Don't eat the whole code

[@CostaKazistov]

C++ to Java is much easier to translate than Python code. The only tricky part are pointers, but concept is pretty straight-forward. So glad Java does not make you work with raw pointers. I did 6 months last year purely in C++ to get good at CP style coding, but really appreciate convenience of Java and even more in Kotlin.

[@adityagaur2223]

Srsly man I was waiting for your graph series and the harder and more complex competitive programming stuff that only a great competitive programmer like you can explain in good as they ain't have much good explanation on KZbin. But since the last few videos have to see these bullshit leetcode videos. And then this comment will be ignored.

Last problem solution is like someone is magically putting correct thoughts in your brain. How does that happen?

[@JDC2890]

You do not want to see the embarrassing messes I made of Apple 'easy' 2, you really don't. The solutions I came up with by myself without looking for help were O(N^2), and exceeded the time limit. With looking at a bit of other stuff I was able to make things better, then I had to look at your stuff. It worries me that I didn't come up with remotely efficient ways of doing the problem.
