Welcome! We're excited to be considering you for a full-stack engineering role at Postman. This folder (which will be the basis for a private GitHub repository) contains several engineering challenges for you to complete over the next few days.
You'll find 3 challenges here, each in its own folder:
challenge-1will test your data processing and pipelining skills. You'll process large files with the Node Streams API and convert CSVs into SQL commands with Knex.challenge-2will test your web scraping abilities. You'll use tools like Crawlee and Cheerio.challenge-3will test your frontend development skills with React. You'll also use new tools like Chakra UI.
Each challenge is self-contained, although they share some NPM modules (which is why the package.json file is out in the parent folder). Feel free to install any other modules that might help you; be sure they're compatible with TypeScript.
You should expect to spend about 6 hours on each challenge.
Before starting this challenge, you should be familiar with:
- TypeScript
- React
- SQL
Each challenge will introduce new tools and libraries, but you aren't expected to be familiar with them already. They're straightforward enough that you should be able to pick them up on the fly. We use these exact same tools inside Postman, so if you end up joining the team, you'll be well prepared for the job.
The main tools you'll need are Node (version 18+) and NPM. Once you've installed these, you should also run this:
npm install --global tsxtsx is a useful tool for running TypeScript files from the command-line, like node is for JavaScript files. You'll be using that throughout the challenge.
Most of the Node.js modules you'll need for these challenges have already been added to package.json, so you'll get them instantly once you do npm install. Take these as helpful hints for which tools you should use when tackling these challenges!
We've also pre-installed a handful of useful utility libraries, such as lodash, immutable, dayjs, and axios.
Feel free to install other packages if you need them!
We use Stack Overflow and ChatGPT on the job, so you're allowed to use them as part of this coding challenge. However, please leave comments indicating which pieces of code you got from Stack Overflow or ChatGPT, including links to any applicable Stack Overflow discussions. And be sure to double-check the code you get from these sources, because they're often subtly wrong or outdated.
You probably got this code as a ZIP file that you unzipped. You should upload this to a new private GitHub repository and start working on it there. Once you're done with the challenge, invite the Postman account as a collaborator on your repository and ping the Postman team to let us know you're done. We'll then start reviewing your work!
Ping us on Slack, email, or however we got in touch with you if you have any questions about expectations or submission. If you find any ambiguity or missing information in this repository, let us know!
