I created an account on HackerMeter to see what the coding exercises looked like. I didn’t even finish creating my account before I was hit with a major disappointment:
A site meant to help rank hackers rejected my 40 character password. Violating this password policy is so bad they had to tell me twice. :-)
Perhaps they should add an exercise to code a password hashing mechanism that supports more than 30 characters. For reference, bcrypt supports up to 72 characters.
