About PrepStack

PrepStack is a tech learning hub for Indian developers, focused on the kind of problems you actually meet on the job: shipping .NET services, mastering React patterns, writing SQL that survives production, and reasoning about system design.

We publish two kinds of content:

• Long-form articles — engineering notes, deep-dives, and tutorials.
• Interview questions — curated questions with detailed answers and code examples, tagged by category and difficulty.
