Tech and sales interviews test very different skills. Developers are expected to explain code trade-offs and system design decisions, while sales professionals must prove quota performance, objection handling, and deal strategy.
Generic AI interview practice fails both groups. When prompts are tailored correctly, AI can simulate realistic technical probes or pipeline deep-dives—building role-specific muscle memory that leads to offers.
Free AI tools adapt instantly to job families. Tech roles get algorithm questions and system design challenges; sales roles face objection handling and forecasting scenarios. This guide shares exact prompts that turn beginners into confident specialists.
Can AI Tailor Prep for Specific Roles?
AI becomes highly effective when given precise role context.
For tech roles, prompts generate:
- LeetCode-style algorithm problems
- System design scenarios
- Debugging and trade-off discussions
For sales roles, AI simulates:
- Cold-call and discovery role-plays
- MEDDIC qualification
- Multi-stakeholder demos and objections
Benefits include about 85% role accuracy, interviewer-style probing, and metrics-focused feedback—similar to what platforms like Careerflow recommend.
Limits: AI needs precise job keywords. Free voice modes can sound robotic for demos. Still, AI covers roughly 90% of technical and behavioral questions.
Result: Tech candidates solve whiteboard problems aloud; sales professionals handle “not now” objections smoothly.
What to Prepare Before Using AI
A 10-minute role-specific setup improves results dramatically.
- Job family: Tech (SWE / PM / DA) or Sales (AE / SDR / AM)
- Keywords: Tech—O(n) time, REST API, A/B testing; Sales—pipeline velocity, MEDDIC, ACV
- Three STAR stories: Tech—debugging, scaling, cross-team work; Sales—quota beat, deal recovery, forecast accuracy
- Tools: Tech—Python, SQL; Sales—Salesforce or HubSpot
- Level: Junior (fundamentals) vs Senior (architecture / enterprise)
Paste this context directly into the prompts below.
Step-by-Step Guide to Role-Specific AI Prep
Use the prompts below and swap in your exact role keywords.
Choosing an AI Tool
Free role specialists:
- ChatGPT: Deep technical explanations
- Google Gemini: Code execution and sales scenarios
- Microsoft Copilot: Natural sales role-play
Giving AI the Right Information
Tech setup prompt:
**TECH INTERVIEW COACH**: [SWE / PM / DA] [Junior / Senior] Keywords: [paste 6 tech terms] My stack: [Python / React / SQL]
Sales setup prompt:
**SALES INTERVIEW COACH**: [AE / SDR / AM] [SMB / Enterprise] Keywords: MEDDIC, ACV, pipeline velocity My metrics: [quota beat %, average deal size]
Example Prompts
Tech: System Design
**SYSTEM DESIGN DRILL**: Senior SWE Ask: "Design a URL shortener handling 1B requests/day" I whiteboard → Probe sharding, caching, rate limiting Score: Scalability, trade-offs, tech choices (1–10) Keywords: O(n) time, CAP theorem, Redis Follow-up: "CEO wants analytics—what changes?"
Sales: MEDDIC Role-Play
**MEDDIC ROLE-PLAY**: Enterprise AE Prospect: "Not now, budget freeze." Apply MEDDIC: Metrics? Economic buyer? Decision criteria? Score: Qualification depth, objection handling Keywords: ACV, pipeline velocity, multi-threaded Objection chain: Budget → Authority → Timeline
Customizing for Each Job
Tech sub-roles:
Frontend: React hooks, performance optimization Backend: Microservices, database indexing Data: SQL optimization, A/B statistical significance PM: RICE scoring, stakeholder alignment
Sales sub-roles:
SDR: Cold email sequences, discovery calls AE: Multi-threaded deals, forecasting accuracy AM: Expansion ACV, churn reduction
Common Mistakes to Avoid
Tech mistakes:
- Vague Big-O (“fast algorithm” instead of O(n log n))
- No trade-off discussion
- Ignoring deployment and production constraints
Sales mistakes:
- Feature dumping instead of outcome selling
- Single-threaded deals
- Weak metrics without ROI context
Fix: Role-specific keywords are mandatory.
Free vs Paid AI Role Prep Tools (High-Level)
| Feature | Free Tools | Paid Plus |
|---|---|---|
| Tech depth | Algorithms + system design | Live code execution |
| Sales role-play | Text scenarios | Natural voice objections |
| Keyword precision | Manual input | Automatic extraction |
| Limits | Peak caps | Unlimited |
Tech vs Sales Prompt Comparison
| Question Type | Tech Prompt | Sales Prompt |
|---|---|---|
| Behavioral | “Debugged slow API (O(n²))” | “Closed $250K deal despite ‘not now’” |
| Technical | “Scale to 1M QPS with Redis” | “MEDDIC qualify Fortune 500 prospect” |
| Follow-up | “What if cache misses spike?” | “Economic buyer asks for ROI proof?” |
20-Minute Role Drill
- Tech: 10 minutes algorithms + 10 minutes system design
- Sales: 10 minutes role-play + 10 minutes forecasting
Success benchmark: 8+/10 role-specific scores.
Final Takeaway
AI can tailor interview prep precisely for tech and sales roles— technical depth for engineers and MEDDIC mastery for closers. Use role-specific prompts, practice 20 minutes daily, and consistently hit 8/10 or higher.
Tech candidates should focus on Big-O and trade-offs. Sales candidates should prove ROI and multi-threading skill. Copy the prompts above, swap in your keywords, and dominate your role’s interview style.
