Features

Everything you need to sound confident

Most candidates fail not because of knowledge — but because of delivery. WhalePrep fixes that.

Personalized interview questions

Upload your CV or a job description to practice interview questions tailored to your exact role, level, and target position.

Real-time speech analysis

AI listens to your spoken answers and analyses pace (WPM), filler words ("um", "uh", "like"), and clarity. You get a score immediately after each answer.

Track progress over time

Your statistics screen shows score trends, WPM history, filler word reduction, and streak. See yourself improving week by week with concrete numbers.

All interview stages

From the Recruiter screen to Technical deep-dives and Team Culture — practice the full sequence. The Recruiter stage is free; Premium unlocks every stage.
