Exponent (now Aced) vs Mockich
Exponent’s site now redirects to Aced, run by the same company. Aced is a broad interview-prep membership: courses for many roles, peer mock interviews, paid coaching and AI practice. Mockich does one thing: spoken mock interviews with a report, for software, data science, machine learning and quant developer roles. Choose Aced for courses, community and human coaching across many roles; choose Mockich for on-demand spoken rounds with quoted feedback.
What Exponent (now Aced) is, as of November 2026
The old Exponent address answers with a permanent redirect to aced.io, and the Aced site carries the Exponent Labs company name. Aced offers courses for product management, engineering management, software engineering, data science, machine learning, data engineering and other roles, interview questions with video answers, peer mock interviews, coaching sessions and job referrals.
Its pricing page lists a free Basic plan with sample lessons and 5 peer mocks a month, a Pro plan shown at $12 a month with $79 struck through, and an Expert plan shown at $20 a month with $99 struck through that adds AI mock interviews, AI interview feedback and an AI coach. The page has monthly and annual billing, and the shown prices may assume annual. Coaching is sold separately.

Choose Mockich if
- You want many spoken repetitions at any hour without coordinating with a partner.
