Interview Types & Formats
Interview format shapes performance as much as interview content. A clean STAR answer delivered on the phone reads differently than the same answer delivered over video or in person — and a technical deep-dive on Zoom has completely different failure modes than the same conversation at a whiteboard. This hub collects our format-specific guides so you can calibrate for the exact round you are facing. Start with the format and add the relevant behavioral and company prep on top.
Phone and Video Screens
The initial phone or video screen is the single highest-leverage round in most hiring loops — not because it is the hardest, but because it is the one most candidates underprepare for. A 30-minute recruiter call decides whether you get into the on-site loop at all. The phone interview guide covers voice-only adjustments (you cannot rely on body language) and the video interview guide covers camera setup, framing, and the lighting mistakes that quietly tank otherwise strong candidates on Zoom and Teams.
Technical Rounds
Technical interviews assess domain expertise through problem-solving, system design, and knowledge-based questions. The shape varies heavily by domain — software engineers face coding problems and system design, data scientists face SQL and case studies, DevOps engineers face infrastructure scenarios — but the core principles are the same: think aloud, structure your approach, and communicate clearly. The technical interview questions guide breaks down the format for each major domain and explains the "think aloud" pattern interviewers explicitly listen for.
Mock Interviews and Second Rounds
Mock interviews are the cheapest, highest-return prep tool available — and the one candidates most often skip because it feels uncomfortable. Even a single 30-minute mock with feedback tends to add more to a candidate's final score than 10 hours of solo study. Second-round interviews are a different shape entirely: longer, more detailed, and often with a panel or hiring manager who will probe deeper into your stories and test cultural fit against the specific team.

Frequently Asked Questions
Should I prepare differently for phone vs video interviews?
Yes. Phone interviews are voice-only so pacing, tone, and clear structure matter more; video interviews add framing, eye contact, and camera angle to the signal set. The two formats are scored against overlapping but distinct rubrics.
How many mock interviews should I do before a real one?
Two to four is the sweet spot for most candidates. One is enough to catch your biggest weakness; two to four is enough to correct it. Beyond four, the returns diminish quickly — you are better off spending the time on targeted content prep.
Do second-round interviews use the same format as first rounds?
Usually longer and more detailed, often with multiple interviewers or a panel. Expect deeper probes into your stories, role-specific scenarios, and cultural fit questions rather than the basic behavioral openers.
