You can see what this lesson covers and the milestone it sets. The full text, code, quizzes, the tutor and the AI reviews come with the K850 practice, along with weekly build sessions and code review.
Milestone forAn observable back-office agent
Remember customers, forget carefully
Store customer aliases (names, phone numbers, typical references) learned from approved matches, separate from conversation context. Decide what persists, what expires and how a wrong memory gets corrected.
Done when
- An alias store written only from approved matches
- Expiry and correction rules in code, not just prose
- A test where a wrong alias is corrected and never used again
Stretch: Measure how match accuracy grows over three months of replayed statements
Reviews open with an access code.
Interview practice
Questions on this topic that AI engineering interviews ask, with the companies reported to ask them. Answer the way you would out loud; Jev scores it and DeepSeek tells you what to add.
Scoring opens with an access code. You can still read the questions and prepare.
