Technical interview best practices
Most reference checks are theater—polite questions yielding polite non-answers. Here are the questions that surface real signal and how to interpret what you hear.
Gut-feel hiring fails 50% of the time. Structured rubrics cut that failure rate in half. Here are the scoring systems that actually predict on-the-job engineering performance.
Pair programming interviews reveal how candidates actually work. Here's the complete guide to running effective pairing sessions—from environment setup to evaluation rubrics.
Engineers spend 25% of their time reviewing code—but most interviews never test this skill. Here's how to implement code review interviews that reveal what whiteboarding can't.
After analyzing 1,000+ live coding sessions, here's what separates signal-rich interviews from anxiety-inducing theater—platforms, problems, rubrics, and interviewer training.
Technical skills get engineers hired; behavioral competencies predict their success. Here's how to design behavioral interviews that reveal how candidates actually work.
Most reference checks are theater—scripted questions, rehearsed answers, minimal signal. Here's how to conduct references that actually reveal whether the candidate will succeed or struggle.
The take-home versus live coding debate has split engineering teams for years. Both have serious flaws. Here's what actually works—and when to use each approach.
ML engineering sits at the intersection of software engineering and data science—making it uniquely difficult to assess. Here's how to interview ML engineers without getting fooled by credentials or confused by jargon.
System design interviews separate senior from mid-level candidates—but only when conducted well. Here's how to run effective architecture discussions that reveal real engineering judgment.
Debugging interviews test skills that whiteboard coding doesn't: reading code, forming hypotheses, and systematic troubleshooting. Here's how to design and run effective debugging rounds.
Panel interviews can be efficient or chaotic—the difference is entirely in the execution. Here's how to structure them for maximum signal without overwhelming candidates, plus the common failures to avoid.
Synchronous interviews limit your talent pool to compatible time zones. Here's how to implement async interview formats that assess effectively without scheduling friction.
Take-home assignments can be your best hiring signal or your biggest candidate turnoff. Here's how to design assignments that work—with templates you can use.
A comprehensive bank of system design questions used by top tech companies, complete with difficulty ratings, time allocations, and evaluation rubrics.
Most technical interviews fail to predict job performance. Learn which questions actually work and how to structure interviews that identify great engineers.
