Why candidates switch from Interview Coder

Full spectrum, not coding-only

Interview Coder is built for LeetCode-style coding and has no behavioral or system design depth. LastRound AI covers coding, system design with diagrams, behavioral, and resume, all in one plan with no per-minute billing.

From $39/month vs $299/month

Interview Coder's monthly Pro is $299 for 1,000 credits, or $799 lifetime (as of June 2026). LastRound AI's Unlimited plan is $49/month for Unlimited interviews (or $39/month on a 3-month plan), and the free plan gives 15 credits a month to try it first.

Free tier that actually answers

Interview Coder's free download gives the stealth overlay and audio capture but not the AI-generated answers. LastRound AI's free 15 credits include full real-time answers.

Works beyond easy and medium coding

Reviews say Interview Coder weakens outside easy and medium coding problems. LastRound AI's language-aware mode plus system design coverage handles harder and broader rounds.
