Howdy 👋 You are here because you think you've got what it takes to join the ranks of an early-stage going into hyper-growth high-tech startup! Now, shall put it to test?
We are in the lookout for beast-mode backend developers, mindful of architecture, data structures, performance and good engineering work — but whom always keep an eye on timely, customer-facing value delivery.
You are proficient in C++, you write clean but high-performance code and know how to take advantage of the internals of your compiler and your toolchain.
But don't be shy! We place great value in education and experience; but we also recognize that talent is built on passion and hours dedicated to deliberate practice and learning... so don't shy away from applying if you feel you have what it takes!
Write a C++ (linux) program "processor" that receives a stream of http "messages" (both inbound and outbound) via unix pipe.
The program maintains a minute by minute aggregation map by request path and response code dimensions.
Messages will not be ordered (you can receive 4 requests in a row, and subsequent responses), so you need to find a means to correlate them.
Every minute the map should be printed to a file indicated by the -o <filepath> argument received by your program.
- your code does what it's supposed to (duh!)
- your code is well organized and extensible (clean code practices)
- your code leverages adequately language features (C++20 and on)
- What would happen if we added messages in another protocol / format?
- What would happen if the message rate exceeded your CPU capacity?
- What would happen if some messages never got a response?
We do favor CLANG and BAZEL for most things -- but feel free to use whatever suites you best at this time. We prefer to see a good structured CMake project if that's more in your toolbelt than a half-baked Bazel one.
Although algos and binary searches and whatnot are important in life... part of your job will be figuring out protocols and building highly efficient data transformation pipelines in resource constrained environments... so it will look a bit (likely quite more complex tho) like this challenge.
Was this too easy?... no worries... this is just a conversation starter.
Also, do not shy away from expanding the functionality as you see fit -- this is a conversation started to discuss your code and technical decisions during our technical interview! Go and shine 😉
It contains a little message generator binary for linux (run it in a non-privileged docker please) that you can use to get the messages streaming -- mind that you need an x86 arch host:
$ ./generator | ./processorPlease be kind to provide Dockerfile(s) to build and and test your code... setting C++ environments can be a bit painful and we have a lot of applications to review!
