General Coding Assessment (GCA): the harder of the two, but manageable with preparation. It's done on CodeSignal, either in person or online. To prepare, practice DSA questions on competitive programming sites like LeetCode, Codewars, and CodeChef for 1–2 weeks, and you should be in good shape. - Source: dev.to / 28 days ago

Plain BST. Fine when input is random or the problem doesn't require worst-case guarantees. Tree problems on LeetCode typically assume balanced input and don't ask you to maintain balance yourself. - Source: dev.to / 4 months ago
Your preparation should not be random. Platforms like LeetCode, Codeforces, and GeeksforGeeks are tools—but what matters is how you use them. - Source: dev.to / 4 months ago

I do workshops with kids occasionally. Last week, 4 13 year old boys. In this case I did breadboarding with them first and then showed them the transfer to fritzing -> breadboard -> schematic -> pcb. https://fritzing.org/ If you're looking for stuff they might find fun, logic noize (for instance https://hackaday.com/2015/03/09/logic-noise-sawing-away-with-analog-waveforms/ ) has a bunch of fun cmos audio tutorials... - Source: Hacker News / 4 months ago

Https://tinyurl.com/yr34sym6 https://wokwi.com/ is great for simple, digital only stuff. https://fritzing.org/ will kind of lay out the PCB for you, but it's kind of a pain in the ass. Wokwi and Fritzing are more "Breadboard Simulators" than real circuit simulators, but they do have their place. - Source: Hacker News / almost 3 years ago
For designing them there are various tools out there. Personally I find https://easyeda.com/ and https://upverter.com/ easier to get started with. Other popular option (but with a much steeper learning curve) are kcad, but I have always found that to be clunky UI. https://fritzing.org/ is another local option that is easy to use but last time I tried it would crash on me all the time making it basically unusable -...

Fritzing - Opensource, a simpler tool but still fully capable. Though last time (many years ago) I tried to use it, despite quite liking it I found it to be very unstable to the point I could not use it without it crashing many times. Maybe that was just my system or maybe things have improved since then though. Might be worth a try. I quite liked it when it was not crashing. Source: over 3 years ago
