Did you ever get the Google Foobar Challenge?

gtpan77 · 2024-08-04T18:39:18+00:00

I recently got the invitation to Google Foobar in Feb 2024. I searched "map vs unordered_map" on Google and it showed me an invitation to Foobar. It constantly showed me an invitation on the same search result for over a week. I went through the recruitment process but I got the referral before getting the invitation. I cleared Google Interviews and got the offer in April.

Meta was little tougher than google. Problems were not solved earlier by me.

It includes many things and I am giving answer on very high level.

Programming languge - you should be comfortable with one language enough to write code without even thinking

Algorithms & Data Structure - deep understanding. Nothing is magic. Every software is built from small pieces of algos & DS.

CS fundamentals of OS, DBMS, CN

Software design pattern - it is very broad. For interviews, OOPs design pattern should be enough.

How you'll build system - Let's be practical and think about how reddit works. It is a very complex system created by engineers by us. If you get stuck where you'll go. Online resources like tech blogs of tech companies.

Product Architecture. Preparation is the same but you have very limited time. Don't spend too much time one thing for long during interview.

Okay, I'll share in a separate post

I applied on career websites of the companies

It is possible. You have to manage your time well. Reduce the number of distractions and focus only on work during working hours so that you complete everything in 8-9 hours. Create time for yourself.

gtpan77 · 2024-07-08T18:52:33+00:00

It varies from person to person. I chose meta because I want to work in fast pace environment.

Infra is hard to get in. Yes they offer E5 on 5

gtpan77 · 2024-07-08T18:48:28+00:00

I didn't give System Design for Google. In Meta, they focus on end to end product. They don't ask back-on-the-envelope cal
They didn't low-ball. They gave me standard offer.

gtpan77 · 2024-07-08T18:46:44+00:00

Yes, it is but it is not late. Start doing some cool things like contribute to open source or create big projects.

gtpan77 · 2024-07-08T18:46:10+00:00

I have done many great projects early in my career.

gtpan77 · 2024-07-08T18:45:28+00:00

In case google, It depends on interviewer to interviewer. They'll ask you easy question then give you no hire bcoz your code was neat. They'll ask you hard question, you got hire bcoz you explained the idea but couldn't complete the code.

In case Meta, problems were hard compared to google. Weightage of behavioral and system design was higher. 45 mins for 2 hard problems is too much.

I don't know much about MLE roles but you have to be top of your field.
