Mechanize Interview Process Notes

Role: Software Engineer

Frequency: Reported (2026 cycle)


Process Shape

Reported first-hand by a candidate (Aug 2026):

  1. R1 — Recruiter call, with two "puzzles" asked live:
    • A probability puzzle: 3 coins, two fair and one not fair — what is the probability that you have a cheated coin (reported answer: 50%). See recruiter-call-puzzles.md.
    • A Fermi estimation: estimate the number of billionaires in the US. See recruiter-call-puzzles.md.
  2. R2 — Take-home, followed by a round where you explain your code for the take-home.

Outreach / Recruiting Style

  • Mechanize reached out to a student club offering $5k if somebody gets an offer (referral-bounty-style outreach).
  • The CEO personally reached out to candidates met at a career fair.
  • Community skepticism was voiced: "I think they are just using people as training data." At least one candidate ghosted the process after a peer's conversation with the CEO.
