[ The workstations ]

One tool for the whole interview cycle

Most candidates prepare in fragments — a keyword list here, a STAR template there, a follow-up email copied from a forum. MockStar connects the four stages of every interview loop into one workflow: tailor the resume, practice, sharpen, follow up.

Tool 01 · Practice

Timed practice rounds

Draw a random set of interview practice questions filtered by role, category, and difficulty. Answer against a two-minute timer, rate yourself, and compare against a model answer with common mistakes.

Tool 02 · Star builder

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.

[ How a round runs ]

How it works

01
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.
02
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.
03
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.
