Training loss falls while validation loss rises? The network may be memorizing. Accuracy can barely move, so keep the epoch with the best validation loss: early stopping. Free course: https://t.co/brDxdU545g #DeepLearning #MachineLearning

“Tell me about a project” isn’t a tool-list question. Say what you built, add real numbers, then explain one decision and its cost. Specifics show how you think. Free AI career course: https://t.co/oaNXZ7S8Ee #Portfolio #CareerChange

You let AI grade AI—but who checks the grader? Swapping reply order changed the verdict on 13 of 102 tickets. Before trusting a model judge, compare it with people and test order effects. Free evals course: https://t.co/L8VbxyLTjB #AIEvaluation #LLM

Prompts guide AI behaviour; code protects data. If a tool can read another shop’s order, “never do that” is not enough. Check user, tenant and resource authorization before every tool call. Free security course: https://t.co/aQE1cgstxU #AISecurity #LLM

A lock file pins packages, not the OS, system libraries or Python version. That’s why an install can fail on another machine. Package the full environment in an image when repeatability matters. Free Docker course: https://t.co/phwWFrXBxM #Docker #DevOps

An AI agent called the same tool 11 times because nothing told it to stop. Give every loop step, time and cost limits—plus a rule for repeated actions—so each run ends for a named reason. Free agent course: https://t.co/e2JLheHBat #AIAgents #AIEngineering

100% of escalations caught—on tickets the model had already seen. On new tickets: 25.1%. Keep training, validation and a sealed test set separate so your final score reflects unseen data. Free ML course: https://t.co/w32eXX81XD #MachineLearning #DataScience

Python tracebacks are easier when read backward: the last line says what failed; the last frame in your own file says where. Debug the cause before editing random lines. Free Python course: https://t.co/PZX4l0ZW7O #Python #Debugging

Changing fields? Domain expertise is an AI skill. Data shows what happened, not why—so surprising model patterns need people who understand the real-world context. Free AI Career Foundations course: https://t.co/oaNXZ7S8Ee #CareerChange #AI

git reset --hard can move your branch without erasing the commit immediately. Check git reflog, find the last good commit, then protect it with a recovery branch. Free Git course: https://t.co/Xx9gkoo3In #Git #LearnToCode

A model can return valid-looking text and still break your app. Ask for structured output with a schema, then validate every response in your code. Build reliable LLM applications: https://t.co/Dn4cP3gPeT #LLM #AIEngineering

One JOIN turned 1,417 ticket rows into 1,893—without an error. After every join, compare row counts and count distinct IDs. A query can run perfectly while your totals become wrong.

“Why did you choose that approach?”

If that question stops you in an AI interview, practise explaining one project: the problem, your decision, the evidence and the limits.

An AI assistant says the policy is 45 days. The source says 30. Don’t trust confidence—require a citation for every claim, then verify each citation in code.

Your document chatbot gives a wrong answer. Did it find the right passage?

Check retrieval before rewriting the prompt. Missing evidence and misread evidence need different fixes.

Your AI assistant passes a test. Run it again: it invents a refund policy.

One passing run isn't enough. Repeat tests, record failures, and judge against clear criteria.
