  • Are you able to talk with Linux freely and you know it is not a species of penguins?
  • Can you perform an API request between applications?
  • Do you know what will happen if you type “rm -rf /*” on production (and no, it does not remove radio frequency)?
  • Have you ever tried port forwarding (CS, Minecraft servers will do)?
  • Do TCP/UDP jokes make you laugh, even though the latter often misses the point?
  • Are you aware that authorization and authentication are two different things?
  • Do you follow any security-related news or do you just WannaCry?
  • Is your English level sufficient to freely read technical documentation?
  • Would you be able to describe complex topics to a non-technical person?
  • Do you constantly level up your tech skills and keep grinding all the time?
If you answered “yes” for most of those questions, do not hesitate and send your application! There is no better time to join cybersecurity ranks than now!
