Recruiter's Cheat Sheet: Spotting Great Candidates
Conversation Starters That Reveal Skill Level
| Question | Junior Answer | Senior Answer |
|---|---|---|
| "Why Gemini vs GPT-4?" | "Google made it" | "Native multimodality for video, 1M token context for long documents, Google Cloud integration for enterprise. Choice depends on multimodal needs and cloud ecosystem." |
| "How do you handle video input?" | "Just upload it" | "Extract key frames or use native video input, consider context limits, specify temporal analysis needs in prompt, optimize for cost vs comprehensiveness." |
| "What's different about multimodal prompting?" | "Add an image" | "Describe what to analyze in the image, specify relationship between text and visual, handle multiple images with clear references, consider output modality." |
Resume Signals That Matter
✅ Look for:
- Multimodal AI projects
- Google Cloud experience
- Video/image processing
- Production AI applications
🚫 Be skeptical of:
- Only text-based AI experience
- No Google Cloud familiarity (if required)
- Demo-only projects
- Generic "AI developer"
Common Hiring Mistakes
1. Assuming All LLM Experience Transfers
Gemini's multimodality requires different thinking than text-only models. Video and image handling, context optimization, and Google Cloud integration are distinct skills.
2. Over-Emphasizing Gemini-Specific Experience
Gemini is one of several capable models. Strong AI engineers with multimodal or Google Cloud experience can learn Gemini specifics quickly.
3. Ignoring Google Cloud Requirements
Most production Gemini use involves Vertex AI and GCP. If your stack is GCP, ensure candidates have cloud platform experience.
4. Testing Text-Only Patterns
If you chose Gemini for multimodal capabilities, test multimodal understanding—not just text prompt engineering.
