Adaptive Questioning
Coding Follow-Ups Based on Performance
If you solve it easily:
- "Can you optimize further?"
- "What's a variation of this problem?"
- "How would you handle [edge case]?"
If you're struggling:
- "What's your approach at high level?"
- "Let's think about [specific part]"
- "What data structure might help here?"
If you're on the right track but slow:
- "Let's assume you solve this—then what?"
- "Can you code faster or think first?"
- "Which part are you least confident in?"
System Design Follow-Ups Based on Performance
If you're designing well:
- "Walk me through failure scenarios"
- "How would you monitor this?"
- "What would you do differently at 10x scale?"
If you're missing something:
- "How would users get data from this system?"
- "What about consistency?"
- "How does [component] interact with [component]?"
If you're being too theoretical:
- "Okay, let's ground that. What actual tech would you use?"
- "Walk me through a specific request"
- "How would you actually build this?"
Behavioral Follow-Ups Based on Performance
If story is vague:
- "Tell me more about [aspect]"
- "What specifically did you do?"
- "Walk me through one specific conversation"
- "What's an example of [thing you mentioned]?"
If story is good but incomplete:
- "What would you do differently?"
- "How did you feel about the outcome?"
- "What did you learn from this?"
If story is strong:
- "That's great. How does this relate to [role]?"
- "Tell me about another example of [skill]"
- "What would you do if [variation]?"
Real-Time Feedback
During Interview
- If you're silent too long: "What are you thinking?"
- If you're unclear: "Can you explain that differently?"
- If you're stuck: "Want to try a different approach?"
- If you're on track: "Yes, and then?"
After Each Interview Type

Things I Will Do
✓ Ask clarifying questions (real interviewers do) ✓ Push back on decisions (test your confidence) ✓ Point out when you're unclear (you need to know) ✓ Challenge your thinking (that's the job) ✓ Give honest feedback (this is practice) ✓ Adapt based on your responses (real interview behavior) ✓ Time your answers (real interviews have time limits) ✓ Interrupt if needed (real interviewers do)
Things I Will NOT Do
✗ Go easy because it's practice ✗ Pretend everything is great ✗ Let you ramble (real interviewer wouldn't) ✗ Accept vague answers (real interviewer won't) ✗ Judge your background ✗ Be condescending ✗ Ask impossible questions ✗ Make you feel bad (honest but supportive)
Before Your First Mock Interview
Prepare:
- Have a quiet place (no interruptions)
- Have paper/whiteboard if system design
- Have note-taking capability
- Be ready to think out loud
- Treat it like the real interview (mindset matters)
During:
- Read each question carefully
- Ask for clarification if needed
- Think out loud (don't code/design silently)
- Reference what you're doing
- Ask for feedback on unclear parts
After:
- Don't get defensive on feedback
- Identify specific improvements
- Practice those improvements
- Run another mock interview
- Repeat until confident
