One tool for the whole interview cycle
Most candidates prepare in fragments — a question list here, a STAR template there, a follow-up email copied from a forum. MockStar connects the three stages of every interview loop into one workflow: practice, sharpen, follow up.
Behavioral interview prep
Turn your experience into structured STAR answers. Step-by-step prompts for Situation, Task, Action, and Result, then a side-by-side comparison with a model answer for the same question.

Follow-up email generator →How it works
1. Draw a round. Pick your target role and difficulty, and MockStar pulls a set of behavioral and situational questions from a curated bank. If an exact match is scarce, the tool widens difficulty first, then role — so you always get a full round.
2. Answer out loud, on the clock. Each question runs against a two-minute timer, the length of a real spoken answer. Practice mode shows STAR hints; mock interview mode hides them and auto-advances.
3. Rate yourself, then compare. After each answer you score yourself 1–5 and immediately see the model answer's key points and the most common mistakes candidates make on that exact question. Progress is saved locally in your browser.
Practice with real questions
A sample from the question bank. Every behavioral question has a dedicated page with a full STAR example answer, common mistakes, and likely follow-up questions.
