The problem

Ever had the experience of bringing a candidate on-site for a technical interview, who appeared like a rockstar programmer on paper, only to find out he performed underwhelmingly below expectation?

Or, the interview tool you are using is drastically inferior to what programmers are using day to day, and is becoming the bottleneck of your interview pipeline?

What's broken?

  • Resumes don't necessarily reflect actual skills
  • Traditional phone screens are imprecise, and susceptible to bias
  • On-site interviews are time-consuming and expensive
  • Existing live coding interview tools are lagging behind

The problem is real. We've all been there.

Fortunately, we have a solution.

Codidate slashes interview turnaround time and costs to 1%.

A better alternative to Codepad

Codidate is the only online coding interview tool that offers advanced code intelligence for many popular programming languages.

With code intelligence, recruiters can better assess candidates' coding skills, their knowledge of libraries, packages, and/or the ecosystem, in both breadth and depth, in an environment similar to their day-to-day IDE.

As a candidate, you probably don't have time for document searches during an interview, and want to avoid being tripped up on small details. Code intelligence comes to the rescue!
