What to Expect and Tips

• 45-minute systems interview, focus on responding to real world problems with an unhealthy service, such as a web server or database. The interview will start off at a high level troubleshooting a likely scenario, dig deeper to find the cause and some possible solutions for it. The goal is to probe your knowledge of systems at scale and under load, so keep in mind the challenges of the Facebook environment.
• Focus on things such as tooling, memory management and unix process lifecycle.

Systems

More specifically, linux troubleshooting and debugging. Understanding things like memory, io, cpu, shell, memory etc. would be pretty helpful. Knowing how to actually write a unix shell would also be a good idea. What tools might you use to debug something? On another note, this interview will likely push your boundaries of what you know (and how to implement it).

Design/Architecture

Interview is all about taking an ambiguous question of how you might build a system and letting

	## Config to make this work

	1. Install Raspberry Pi Imager, and install Octopi from there to your Raspberry PI.
	2. Make sure your raspberry pi is not showing any voltage errors. Or get a decent power unit/cable that can handle 2.5A.
	3. Start your octoprint server, login, put the
	4. For the network I used a RJ45 ethernet port since I dont have a wifi module.
	5. For the serial connection to your Sovol, use a usb cable, but use electrical tape to cover the power pin (+VCC). (Last pin from the right).
	6. The step above is crucial to not mess with the sovol power delivery.
	7. If you want to print directly from sovol cura software, follow this helpful video by Bryan: https://www.youtube.com/watch?v=tx84EG-Il9o.
	This should help setup the API Keys, which allows to print directly from the slicer.
