Show HN: Prepin just launched 15 interview categories for mock interviews

We just rolled out a major update to Prepin with 15+ specialized interview categories. You can now practice mock interviews tailored to your specific field, from Software Engineering to Data Science to Product Management.

Try it out: You can jump straight into a mock interview and see how it feels. The categories really make a difference in getting relevant, targeted practice. Would love feedback from the community - especially on which categories we should prioritize expanding next!
