Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

Stores data elements based on an sequential, most commonly 0 based, index.
Based on tuples from set theory.

Pull Request Etiquette

Why do we use a Pull Request workflow?

PRs are a great way of sharing information, and can help us be aware of the changes that are occuring in our codebase. They are also an excellent way of getting peer review on the work that we do, without the cost of working in direct pairs.

Ultimately though, the primary reason we use PRs is to encourage quality in the commits that are made to our code repositories

Done well, the commits (and their attached messages) contained within tell a story to people examining the code at a later date. If we are not careful to ensure the quality of these commits, we silently lose this ability.

Login inside the container/bash into container/get inside the container []=you need to replace it with your own container/image parameter

docker run -dit [image_name]

By ID

docker exec -i -t 665b4a1e17b6 /bin/bash

By Name

docker exec -i -t loving_heisenberg /bin/bash

	# N.B. The only tool missing here that is mentioned in the document is `zenmap`
	# purely because this image is intended to be run via a CLI and `zenmap` is a GUI
	# to `nmap` i.e. one can play around with the tools by running:
	#
	# $ docker build --name bite_size_networking:latest .
	# $ docker run --rm -d --name bsn_test bite_size_networking:latest
	# $ docker exec -it bsn_test bash
	#
	# Alternatively, one can change the `ENTRYPOINT` to `["bash"]` and run:
	#

	.SYNOPSIS
	Using AppName the script will find all variables for that project.
	It will then look at EnvironmentToCheck for variables that have
	been configured in other environments but not the one specified

	i.e.

	A variable named "Test" under the scope of a "Test" environment
	will be reported if a "Test" variable under the "Prod" environment

	#! python
	import shutil
	import sys
	import json
	from flatten_json import flatten

	# Author: Lalit kale
	# Tested with python version 3.6.6
	# This is the program through which build engineers can transform appsettings.json file
	# into Octopus Deploy tool's variables in the format required by my employer.
