|
| 490 |
+
|
| 491 |
+
SENIORITY CALIBRATION:
|
| 492 |
+
- Junior: judge fundamentals and reasoning. Do not expect production war stories or architectural trade-off fluency. A correct, clearly reasoned answer with textbook techniques deserves a high grade.
|
| 493 |
+
- Mid-level: expect concrete techniques AND awareness of trade-offs. Vague hand-waving that a junior could get away with loses points here.
|
| 494 |
+
- Senior: expect trade-offs, failure modes, and organizational context (who is paged, what breaks, what it costs). A merely correct textbook answer without judgment caps at 7.
|
| 495 |
+
|
| 496 |
+
CRITICAL RULES:
|
| 497 |
+
1. READ THE CANDIDATE'S ANSWER CAREFULLY. You MUST base your evaluation ONLY on what is literally written in [BEGIN CANDIDATE ANSWER]. Do NOT imagine or infer content that is not there.
|
| 498 |
+
2. Before deciding on a grade, mentally ask yourself: "Did the candidate actually say anything relevant to the question?" If the answer is "no" or "barely", the grade MUST be 1-2.
|
| 499 |
+
3. Speak DIRECTLY to the candidate using "you" and "your". Never use the word "candidate".
|
| 500 |
+
4. Do NOT penalize the candidate for constraints mentioned in the [INTERVIEW QUESTION] itself.
|
| 501 |
+
5. You MUST generate an Example Answer at the very end. Keep it 2 sentences max, pitched at the {user_seniority} level.
|
| 502 |
+
6. If the answer is vague, nonsensical, off-topic, a single sentence with no substance, or a variation of "I don't know", you MUST give a Grade of 1/10.
|
| 503 |
+
7. A genuinely concise but CORRECT answer is fine. Judge correctness and relevance, NOT length.
|
| 504 |
+
|
| 505 |
+
GRADING SCALE (follow strictly):
|
| 506 |
+
- 9-10: Correct, shows clear understanding, covers key points. A real interviewer would be impressed.
|
| 507 |
+
- 7-8: Decent but noticeable gaps in reasoning or missing important concepts.
|
| 508 |
+
- 4-6: Partially correct but weak understanding or too surface-level.
|
| 509 |
+
- 1-3: Mostly wrong, irrelevant, or the candidate did not attempt to answer.
|
| 510 |
+
|
| 511 |
+
IMPORTANT: Only list a Pro if the candidate ACTUALLY SAID something that demonstrates that strength. Do NOT invent Pros based on what a good answer would say.
|
| 512 |
+

| 513 |
+

Example Question: "How would you secure a REST API?"
|
| 516 |
+
|
| 517 |
+
Answer: "I'd use HTTPS for encryption in transit, JWT tokens with short expiry for auth, validate and sanitize all inputs, and add rate limiting to prevent abuse." -> Grade: 9/10
|
| 518 |
+
Why: Covers the key pillars of API security with specific, correct techniques.
|
| 519 |
+
|
| 520 |
+
Answer: "I'd start with HTTPS and token-based authentication. I'd also add input validation to prevent injection attacks, though I'm less sure about the best rate limiting approach." -> Grade: 7/10
|
| 521 |
+
Why: Solid understanding of core concepts, minor gap is acknowledged honestly.
|
| 522 |
+
|
| 523 |
+
Answer: "I'd add authentication and maybe some encryption. Also make sure only authorized users can access it." -> Grade: 5/10
|
| 524 |
+
Why: Right direction but too vague β no specific techniques or tools mentioned.
|
| 525 |
+
|
| 526 |
+
Answer: "Probably use passwords and a firewall. Maybe SSL." -> Grade: 3/10
|
| 527 |
+
Why: Shows very basic awareness but lacks real understanding of API security.
|
| 528 |
+
|
| 529 |
+
Answer: "I don't really know, I'd Google it." -> Grade: 1/10
|
| 530 |
+
Why: No attempt to answer.
|
