Real runtimes
15+ languages, proper execution
Python, Java, Go, Rust, TypeScript, C++ - real code execution. Install common packages. Run output and stderr in real time.
Real runtimes. Real problems. Ranked candidates.
Engineering hiring should test engineering - not memorization of LeetCode's top 150. Real problems in real runtimes, hidden test cases, and architecture and design discussions. Your engineers only interview candidates who demonstrated the bar.

Why this matters
Most coding tools test the wrong thing
Memorized trivia. Pasted LeetCode. Synthetic problems no one debates in real engineering. The best coding assessments test how a candidate breaks down a real problem, trades off correctness and clarity, and debugs when tests fail. GoodFit's coding product is built for this.
Hidden test cases
Edge cases candidates cannot paste through
Public tests describe intent. Hidden tests enforce it. Copy-paste solutions fail the edges - which is often where bugs really hide.
Attempt history
Watch how they debug
Every run is logged. Compare the first attempt to the final submission. Pasted-in code shows up clearly. Evaluate the thinking, not just the answer.
Voice + coding
System design via conversation
AI voice interview covers system design, how they weigh different options, and past-project depth. Engineers bring the panel-level questions.
Customer story · Xcelore
Xcelore screens 5 tech profiles through AI coding + voice - ranking candidates before engineering panels step in.
Before GoodFit, the process was entirely manual. Recruiters reviewed every resume, then invited shortlisted candidates to full-day in-person rounds. There was no early filtering layer, a lot of time spent before anyone knew whether a candidate could actually code.
