Raw Score: 42/100Detected Gaps in Current Draft
Production-Engineered Bullets
Internship ReadyArchitected multi-agent customer query router in FastAPI and LangGraph, implementing schema-validated function calling and dynamic fallback to smaller local SLMs during API outages.
Engineered two-tier RAG retrieval using pgvector with hybrid BM25 search, reducing context window tokens by 38% and dropping p95 retrieval latency from 1.4s to 310ms.
Built automated evaluation harness over 450 synthetic edge cases measuring retrieval recall and tool hallucination rate, achieving 94.2% task completion fidelity.
Integrated Redis semantic response cache and token rate limiter, cutting third-party model inference costs by 47% under simulated 120 req/sec load.
Audit Rubric Matrix: Toy Wrapper vs Production Signal
| Evaluation Pillar | Typical 5th Sem Student Bullet (High Rejection) | Optimized Systems Engineering Alternative | Why Recruiters Reject The Former |
|---|---|---|---|
| Evals & Hallucinations | "Used LangChain and OpenAI to answer queries with 95% accuracy." | "Constructed 450-scenario eval harness with RAGAS, tracking context precision and reducing hallucination to <2.1%." | No one achieves "95% accuracy" on open-ended LLMs without an automated ground-truth eval dataset. |
| Latency & Throughput | "Used ChromaDB and embeddings to do fast semantic search." | "Configured HNSW indexing in pgvector with Redis semantic cache, dropping p95 latency from 1.8s to 240ms." | "Fast" is meaningless. Teams want percentiles (p50/p95), cache hit rates, and embedding dimension costs. |
| Failure Modes & Resilience | "Connected agent tools with OpenAI function calling." | "Engineered Pydantic schema validation with exponential backoff and SLM fallback on rate limit / tool error." | External LLM APIs routinely fail, throttle, and hallucinate parameters; code without fallbacks won't survive production. |
