WHAT LEARNERS SAY
“I failed three online assessments in a row — same story every time. Nia showed me it was the same two patterns and built a two-week ramp. The fourth assessment turned into an offer.”
ANANYA S. · SDE-1 · PLACED 2026
“I come from a non-tech background and dreaded the aptitude round. Nia taught it like a patient mentor, not a question bank — I walked into the consulting assessment calm.”
MIGUEL R. · MBA CANDIDATE
“The written feedback after every mock is the thing nobody else gives you. It told me exactly why I ran out of time on Q3 — and how to never let it happen again.”
