Hello Interview vs Revarta: FAQ

Is Hello Interview's system design content better than Revarta's?

For pure system design deep-dives, Hello Interview has excellent written guides. But reading about system design and articulating it in an interview are different skills. Revarta helps you practice explaining concepts clearly under pressure—which is what actually gets tested.

Can I use Hello Interview and Revarta together?

Absolutely! Many engineers use Hello Interview to learn system design concepts, then use Revarta to practice articulating those concepts clearly. Hello Interview teaches the 'what'—Revarta trains the 'how to communicate it.'

Why do I need behavioral prep if I have technical skills?

Tech interviews increasingly weight behavioral rounds. At companies like Amazon (Leadership Principles) and Google (Googleyness), behavioral interviews are often the deciding factor. Strong technical candidates fail all the time on behavioral rounds. Revarta prepares you for both.

Does Revarta have system design practice?

Revarta includes questions about technical concepts, architecture decisions, and trade-offs—framed as interview questions. For whiteboard-style system design with diagrams, Hello Interview or similar tools are better. Use Revarta for the verbal explanation component.
