Real stories from engineers who transformed their careers with thita.ai

I spent thousands on interview coaching before finding thita.ai. The AI gives similarly detailed feedback, available instantly, at a fraction of the cost. The code review feature caught edge cases I always missed. This platform is seriously underpriced for what it offers.

With a full-time job and family, I could only study late nights. Unlike other platforms that require scheduling with peers, thita.ai's AI interviewer was always available. Practiced during my own hours and cleared my interviews after 2 months of consistent prep.

Unlike platforms where you just grind problems, thita.ai focuses on pattern recognition and problem-solving approaches. The AI explains the 'why' behind solutions, not just the 'what'. This helped me solve new problems I'd never seen before in my actual interviews.

Honestly better than $300/hour interview prep sites. I've tried probably 8 different platforms. thita.ai has the cleanest interface and smoothest experience. The code editor, real-time feedback panel, and session summaries are incredibly well-designed. Makes practicing actually enjoyable instead of a chore.

After each coaching session, thita.ai generates detailed notes with visual diagrams explaining my solution and alternatives. I've built an entire reference library from these notes. Reviewed them right before my interviews and it gave me such clarity and confidence.

As someone with 5 years experience, most platforms felt too basic. thita.ai's AI quickly assessed my skill level and challenged me with appropriate problems. No more wasting time on easy questions went straight to the stuff I actually needed to practice.

Before thita.ai, I was hopping between random YouTube videos and blog posts with no clear direction. This platform gave me structure and a roadmap. The organized content meant I wasn't wasting time on topics I already knew.

I struggled with system design for months after passing DSA rounds at multiple companies. thita.ai's structured approach and instant feedback helped me finally understand the patterns. I feel much more confident in system design interviews now. The AI coaching is like having a personal mentor available 24/7.

I've done mock interviews on Pramp and interviewing.io, but thita.ai's AI interviewer feels the most natural. It asks follow-up questions, challenges your assumptions, and even gets slightly impatient if you're overthinking just like real interviews! This realism made me way more prepared for the actual thing.

I read "Designing Data-Intensive Applications" and watched countless YouTube tutorials but still blanked during interviews. thita.ai broke down system design into digestible patterns and components. The interactive diagrams helped everything click.
