You can also find me on the Fediverse @[email protected] and on LinkedIn.
It comes in many formats, some require you to solve a question before moving on to the next, others are jeapordy style where you can choose any question among different categories at any time. If you like solving puzzles or following clues to find a root cause then these are great exercises.

If you've read this far and you have no idea what a CTF is, then kudos to you. In short CTF stands for Capture The Flag, you're given a question and often an artifact or piece of evidence and have to answer the question.

A lot of cybersecurity cons run CTF competitions, the recent virtual PancakesCon (pancakescon.com) offered a CTF.

You can find a list of upcoming CTFs at ctftime.org
Also MetaCTF (metactf.com) runs some short notice Flash CTFs.

If you have done CTFs then it's a great talking point in an interview. Here are some of the slightly more casual/accessible CTFs:
nationalcyberleague.org (HS and college)
www.uscyberpatriot.org (HS level)
www.sans.org/cyber-ranges... (non-competitive)
National Cyber League Webpage
The NCL is a learning-centered cybersecurity competition and community for high school and college students.
