The short version

  • Each has a real cost: Gem pricing outside the small-startup tier is entirely custom and not published, so mid-size and enterprise buyers cannot benchmark cost before a sales call; 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.
  • They diverge on capability: Gem covers AI sourcing, HackerRank covers Coding assessments.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A larger engineering organisation needing unlimited user seats across many hiring managers, better served by Pronot Gem

  • An organisation that wants a large, established question library spanning algorithms, system design and role-specific skillsnot Gem

Where each one falls short

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

Gem

  • Pricing outside the small-startup tier is entirely custom and not published, so mid-size and enterprise buyers cannot benchmark cost before a sales call
  • Choosing Gem All-in-One as an ATS replacement is a much larger migration decision than adding a sourcing layer, and the sales process does not surface that distinction clearly upfront
  • Seat types (standard versus AI-powered) gate which features a given recruiter can use, so a team can under-provision seats and lose access to sourcing features they assumed were included
  • The startup discount programme has eligibility cutoffs by employee count and age of company, so growing past 30 employees or beyond early stage removes the cheaper pricing path
  • Outreach effectiveness depends on email deliverability and candidate response rates that Gem does not control, so ROI varies by how saturated a company's target talent pool already is with recruiter outreach
  • Switching from Gem back to a standalone ATS after adopting All-in-One means re-migrating hiring pipeline data a second time, which is a cost most buyers do not model at signup

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.

Answered from the vendors’ own pages

Gem: Do we need to replace our ATS to use Gem?

No, Gem can run alongside an existing ATS purely for sourcing and CRM; Gem All-in-One is a separate option that includes its own ATS.

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.

Gem: Is there a published price for larger teams?

Only the 1-10 employee startup tier has a public price; larger teams are quoted based on FTE count and seat mix.

HackerRank: How many users does Starter support?

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

Gem: What is the difference between a standard and AI-powered seat?

Standard seats cover core sourcing, email-finding and ATS sync; AI-powered seats add sourcing agents, application review and fraud detection.

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.
