This is a tech screen exercise. It is very similar to a task we need to perform sometimes in our production environments.
You are provided with a collection of dummy sample text files. They are available here.
The task is to write a program (file_metadata.py or in golang) that provides us with a csv file (interview.csv) that contains the following information about these sample_file_*.txt files:
- File name
- Sha256 hexdigest of the file
- File size
- Word count
- Number of unique words in this file
- Todays date (In format YYYY-MM-DD)
The above information should be in a csv file called interview.csv. The File size should be provided in bytes. For the word count, assume that space is the delimiter between words.
E.g. the first line of your interview.csv would be:
sample_file_0.txt, 89abab31bc4c08205ea4190cac98deb0b9844da121acff9de93ea41adade8a75, 371240, 32025, 29449, 2019-01-24
No github creds are needed to programmatically access these files. Wrap this up in a docker container. The container should be named: cs-<firstname>-<lastname>-file-metadata:0.0.1. Provide us with a dockerfile so that we can build the container, do a docker run command and it will deposit the interview.csv in the current directory. After we execute your docker run we should be able to see the answer by doing: cat interview.csv. Feel free to use all usual resources available on the internet as you would do in your normal working. As a request, please don't share your solution or ask others to do it for you !
NOTE: Don't git clone the sample-files repo. Programmatically pull the files down in your submission.
Please write this code as if you were doing it in a production peer-reviewed setting. Add anything you think is important and feel free to impress us !
A zip / tgz file containing everything required for this assignment. Please include a README.md file giving details how to build, run, and test your container.

Are we supposed to programmatically access these files thru the web eg make a web call to github to download these files and process them or can we download them locally and include them in our docker?
The program has to programmatically download them via a web call. We will run your program and it should download when we run as well.
