Case Studies
Real candidates. Real preparation. Real offers.
Detailed breakdowns of how specific candidates used InterprepAI to identify their weaknesses, fix them through targeted practice, and land offers.
What happened
Arjun had solved 300+ LeetCode problems but froze during his first Google loop when asked to extend a system design in real time. Four InterprepAI sessions focused specifically on follow-up pressure scenarios. He passed his second attempt.
Key insight
His technical depth score was 91/100 — the problem was communication under follow-up pressure. He knew the answers but couldn't articulate them when challenged. We trained exactly that scenario.
Score progression
"The follow-up questions caught me completely off guard — exactly like what happened in my real Google interview the next week. I felt so much more prepared."
What happened
Marina had 6 years of product experience but consistently struggled to communicate the "why" behind her decisions clearly. Her reports showed weak scores on Problem Structure and Strategic Thinking. Eight sessions over three weeks transformed her answer architecture.
Key insight
Most candidates with Marina's background lead with solutions. Her reports revealed she was answering product design questions by designing features, not solving user problems. Three sessions focused on this specific pattern reset her thinking.
Score progression
"I practiced 8 sessions over two weeks. The report showed my STAR structure score going from 58 to 89. I got the PM role at Stripe."
What happened
David was a strong designer but felt his interview performance didn't reflect his work quality. His reports revealed a pattern: strong on expertise, weak on the behavioral layer — how he collaborated, handled disagreement, and led without authority.
Key insight
Designers often underestimate how heavily they're evaluated on soft skills in interviews. David's design thinking was exceptional; his behavioral scores were dragging his overall performance. Three targeted behavioral sessions changed the outcome.
Score progression
"Having a face to talk to changes everything. Text-based prep never made me this nervous — and that pressure is exactly the point."
