Attempts per year, or candidates per month
HackerRank's Starter plan is $79 a month billed annually for 60 candidate attempts a year, and Pro is $419 a month for 360. Every extra attempt is $20, and unused attempts expire at the end of the billing cycle. TunnelQuiz's Essential plan is $34 a month billed yearly for 150 credits every month, and one credit is one candidate sitting. On Starter, a 400-person aptitude round uses the year's 60 attempts on its first 60 candidates.
