Where they pull apart

HackerRank

Stands out: Chakra AI interviewer, Screen, and live Interview on every plan, with MCP and API on Enterprise.

Watch out: Starter and Pro do not include API or MCP. Extra attempts are $20 each. ATS hooks start on Pro.

Not the right fit for

  • Teams that need API or MCP on a self-serve plan
  • Buyers who only want a free developer practice site

Karat

Stands out: Expert interviewers run the technical interview, backed by benchmarks from 600,000-plus interviews.

Watch out: No public rate card. You buy a scoped interview program after a demo, not software by the month.

Not the right fit for

  • Teams that only need a coding pad
  • Buyers who need a published price

Karat

  • Interviewers included, not only software
  • Consistent bar across teams and regions
  • Benchmarks from 600,000-plus interviews
