Interview practice,
organized by company.
PCT supplies current company and role diligence. PCV supplies the selected, evidence-bounded CV. PIT turns both into timed simulations, fresh problems, scorecards and repair work.

Interview labs
Company- and role-family preparation / fictional cases / explicit evidence gates
Jane Street interview lab
Run all eight Package 004 role labs: TDOE, Infrastructure Automation, Data Engineer, Quantitative Research, Strategy & Product, MLE, MLR and SWE.
General Quant role-family lab
Package 006 tests research validity, Python implementation, portfolio construction, risk, and a final evidence defense without pretending one firm has one universal process.
HKUDS research application lab
Run the compact PhD 001 research-fit simulation. Package 007 adds the complete proposal, experiment and supervisor-panel defense.
Tencent Hunyuan interview lab
Package 008 separates Agent Harness, RL Framework, and RAG/Agent engineering into three evidence-bounded simulations; current role activity still requires a manual official-page check.
Operating protocol
Do not memorize. Expose the gap.
- 01Select one role and one CV.
- 02Solve a fresh problem out loud.
- 03Score evidence, judgment and correction.
- 04Build one bounded repair artifact.
