The short version

  • Each has a real cost: HackerRank the Starter tier meters candidate assessment attempts (120 a year included) with roughly 20 US dollars per additional attempt, so a hiring surge or an unexpectedly popular job posting turns directly into overage costs.; Karat pricing is quote-only, so a buyer cannot model cost per hire against internal interviewer time without a sales conversation
  • They diverge on capability: HackerRank covers Coding assessments, Karat covers Interview Engineers.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

HackerRank

  • The Starter tier meters candidate assessment attempts (120 a year included) with roughly 20 US dollars per additional attempt, so a hiring surge or an unexpectedly popular job posting turns directly into overage costs.
  • Starter includes only one user licence, so any team with more than one recruiter or hiring manager needing direct platform access must jump to the far larger Pro commitment.
  • The jump from Starter to Pro is a large step, roughly 100 to 450 US dollars a month, with no published mid-tier option for a team that has outgrown Starter but does not need Pro's full scale.
  • As with any automated coding assessment tool, heavy reliance on it as an early filter risks screening out strong candidates who underperform in artificial timed test conditions.
  • Enterprise-tier features such as custom question libraries and SSO are quote-only, making full cost comparison against Codility or other competitors impossible without entering a sales process.

Karat

  • Pricing is quote-only, so a buyer cannot model cost per hire against internal interviewer time without a sales conversation
  • Handing the interview itself to a contractor removes the one part of the process where candidates meet a real employee, which can weaken employer brand for roles where culture fit matters most
  • It solves interviewer capacity for technical screens but does not replace hiring manager or team-fit rounds, so it only removes part of the funnel
  • Quality depends on how well the client-provided rubric and questions are written; a poor rubric produces poor Karat interviews just as it would internally
  • Contracted interview volume can create pressure to keep using the service even after an internal hiring slowdown, since commitments are typically annual
  • Candidates sometimes react negatively on discovering the interviewer is not an employee of the company they applied to, which is a reputational risk not visible until candidates start talking about it publicly

Answered from the vendors’ own pages

HackerRank: What happens if we exceed our included assessment attempts on Starter?

Each additional attempt beyond the included 120 a year is billed separately, at roughly 20 US dollars per attempt.

Karat: Do candidates know they are being interviewed by a contractor rather than an employee?

Karat discloses that Interview Engineers are trained third-party interviewers rather than employees of the hiring company, though disclosure practices are set by the client.

HackerRank: How many users does Starter support?

One user licence; teams needing more than one seat must move to the Pro plan.

Karat: Can Karat interview for languages or stacks outside mainstream web and backend engineering?

Coverage depends on the pool of Interview Engineers Karat maintains for a given stack; niche or highly specialised roles may have less coverage than common web and backend roles.

HackerRank: Does HackerRank offer live interviews as well as automated tests?

Yes, both a Screen module for automated assessment and an Interview module for live, collaborative technical interviews are included from Starter upward.

Karat: Is pricing per interview or per contracted block of volume?

Karat does not publish pricing; it is quoted per client based on expected interview volume and contract term.
