Tech Job Hunting

Mock Interview Sites

Would advise you all to practice just for fun. I know a lot of students don't get much practice for interviews.

• interviewing.io - Allows you to have mock interviews with engineers from the bay area. I personally like this platform a lot and used it as an interviewee.
• Pramp - Peer-to-peer mock interviews. You get matched with another person, get assigned questions and take turns to be interviewer/interviewee. I personally dislike this platform a lot because I had a horrible experience being matched with some guy who didn't know shit about regular expressions, gave me a wrong test case, and led me down the wrong path of solving the question.

# We want to sort a list by its second element in descending order.
# The example illustrates the difference in the results of different
# process of sorting in descending order.

# Sort in ascending order, then use list reverse
>>> a = [('A', 1), ('C', 5), ('A', 2), ('B', 3), ('B', 5)]
>>> a.sort(key=lambda x: x[1])
>>> print(a)
[('A', 1), ('A', 2), ('B', 3), ('C', 5), ('B', 5)]
>>> a.reverse()

Adding "Copy" (to Clipboard) Button

If you would like to add a button to your fenced code blocks so that users may copy the code, you can do so in Docusaurus. You will have to add some code to your Docusaurus project, as seen below.

Under static/js, create a file called code-block-buttons.js with the following:

// Turn off ESLint for this file because it's sent down to users as-is.
/* eslint-disable */
window.addEventListener('load', function() {

	prettier-eslint	eslint-plugin-prettier	eslint-config-prettier
What it is	A JavaScript module exporting a single function.	An ESLint plugin.	An ESLint configuration.
What it does	Runs the code (string) through prettier then eslint --fix. The output is also a string.	Plugins usually contain implementations for additional rules that ESLint will check for. This plugin uses Prettier under the hood and will raise ESLint errors when your code differs from Prettier's expected output.	This config turns off formatting-related rules that might conflict with Prettier, allowing you to use Prettier with other ESLint configs like eslint-config-airbnb.
How to use it	Either calling the function in your code or via [prettier-eslint-cli](https://github.co
