Hiring guide for F1 Engineers

F1 Developer Hiring Guide

F1 is a unique programming language, emerging from the heart of Amazon Web Services (AWS). Its inception was driven by the need for a high-speed, distributed relational database system capable of handling the colossal volume of Amazon's e-commerce operations. In its essence, F1 is a contemplative response to the limitations of traditional relational databases and the inability of NoSQL databases to meet all the needs of complex applications. The thoughtful design of F1 reflects an understanding that relational databases are not obsolete, but rather need to evolve to meet the challenges posed by web-scale traffic and cloud computing. The core strength of F1 lies in its ability to handle immense workloads, providing high availability and strong consistency across globally distributed data centers. It is an embodiment of resilience and durability, deftly handling hardware or network failures with minimum impact on application performance. F1's architecture is a testament to the power of hybrid systems. It combines Google's Spanner database for globally-distributed data storage and synchronization with a SQL-based relational model, reflecting a deep understanding that innovation often involves combining existing technologies in new and creative ways. F1 also signifies a significant shift towards polyglot persistence in database management. By supporting multiple data models within a single integrated backend, it allows developers to choose the best tool for each job, fostering flexibility and efficiency. However, beyond its technical prowess, F1 represents a philosophical shift in database design. It challenges the dichotomy between NoSQL and SQL databases, advocating instead for a nuanced approach that recognizes the strengths and weaknesses of both paradigms. F1 is not just a programming language; it's a statement that complexity can be tamed with thoughtful design. In conclusion, F1 is more than just another cog in Amazon's giant machine; it is an intellectual endeavor that encapsulates years of experience and learning in database management. It's a testament to human ingenuity and adaptability - proof that even in our digital age, thoughtful design and deep reflection can lead to groundbreaking innovations.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with F1.

What does this code do?
'key': 'value'
This code defines a dictionary with a single key-value pair, where the key is 'key' and the value is 'value'.
What will be the output of the following piece of code?
'foo': [1, 2, 3, 4, 5][::-1]
This code will output a dictionary with key 'foo' and the value being the list [1, 2, 3, 4, 5] reversed, so the output will be {'foo': [5, 4, 3, 2, 1]}.
What does this code do?
'collection': [1,2,3,4,5].map(function(n) { return n * 2; })
This code defines a dictionary with a key 'collection' and value as the list [1,2,3,4,5] where each element is multiplied by 2. So the output dictionary will be {'collection': [2, 4, 6, 8, 10]}.
What does this code do?
'thread': function() { setTimeout(function() { console.log('Hello World!'); }, 1000); }
This code defines a dictionary with a key 'thread' and value as a function that waits for 1 second (1000 milliseconds) and then prints 'Hello World!' to the console.
