AceStack AI is an AI technical interview coach and practice platform. It maps the likely interview loop for a target role and seniority, opens a round-specific workspace, supports the attempt, evaluates the submitted evidence against explicit criteria and recommends the next drill.
Free launch scope covers HR and technical screening, Algorithm coding, multi-file Platform coding and SQL case practice. Focus adds Behavioral. Problem Solving, Debugging, Low-Level Design, System Design, ML, data, DevOps and SRE workspaces are coming soon.
AceStack AI is built for Junior, Middle, Senior and Staff-level candidates preparing for frontend, backend, full-stack, machine learning, data, MLOps, DevOps, SRE and platform engineering interviews.
The selector uses role, specialization, seniority, company environment, difficulty, topic coverage, readiness gaps, and previous attempts. A Frontend candidate targeting Big Tech should not receive the same path as a Backend candidate preparing for a startup loop.
Every task has explicit criteria and seniority-specific expectations. The same universal question can be shown to Junior, Middle, and Senior candidates while ownership, depth, trade-offs, and pass thresholds are evaluated at the appropriate level.
Free includes AI review on eligible work and uses the result to update Readiness. Focus adds AI Coach and step-by-step help inside the task, so you can ask for the next move without revealing the full answer.
Neither description is complete. AceStack AI builds a role-specific interview pipeline, records attempts by stage, measures readiness and routes the next practice session to the weakest signal.
AceStack AI does not freeze preparation around an old question list. It finds current hiring-loop signals, verifies the pattern, then builds original practice around what candidates need to prove today.
We scan public interview reports, role pages and hiring updates.
We check the date, compare sources and review every report.
We turn verified patterns into original tasks and clear score rules.
