About ProLearnX

ProLearnX is an interview-prep platform covering 100 career roles, with the top 100 questions each. The content was originally published as paperbacks and Kindle e-books on Amazon under the DollarBook series. The same content now powers this web experience: free for the first 20 questions of every role, with the full set available either on Amazon or via web unlock.

Each book draws on real interview loops at FAANG-tier companies and high-growth startups. The questions are organized by topic and difficulty, with sample answers, key talking points, and follow-up drills.
