NOTE: please don't actually use this in your coding interviews. IMO the best way to prepare for a coding interview is still the old way, i.e.: really understand your data structures and algorithms, as well as the programming language and tech stack of your choice (or those required by your potential employer, of course).
This is a super simple app that allows you to ask questions about a coding interview question verbally, and have ChatGPT send you back the answer. As usual, with LangChain, the core of the app is just a few lines of Python code. I spent the vast majority of the time fighting with the HTML/CSS/JS. (Of course they were ChatGPT-generated, but I had to tinker with them a bit more to make them look a bit more decent.)
You need to have an OpenAI API key. You can get one here.
Set it as an environment variable called OPENAI_API_KEY.
I'm using Python 3.9.
pyenv and the pyenv-virtualenv plugin are highly recommended to keep your Python versions and environments cleanly separated.
Once you have them installed and have the virtual environment activated, then install the dependencies:
pip install -r requirements.txt
