"@type": "Question",
"name": "How are startup accelerator company interviews different from FAANG interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Accelerator-backed startups (YC, a16z, Sequoia portfolio companies) have shorter, more pragmatic interview processes than FAANG. Expect 2-4 rounds rather than 5-7. Technical rounds often include take-home projects or pair programming on real codebases instead of isolated algorithm puzzles. Startups prioritize breadth — they need engineers who can own full features end-to-end, debug production issues, and ship fast. Culture alignment is weighted more heavily since small teams feel team dynamics acutely."

"@type": "Question",
"name": "What should I highlight when interviewing at a Series A or B startup?",
"acceptedAnswer": {
"@type": "Answer",
"text": "At early-stage startups (Series A/B), emphasize ownership stories: systems you built from scratch, production incidents you resolved, and features you shipped independently without heavy process. Startups are allergic to candidates who need rigid requirements or extensive code review cycles before shipping. Highlight adaptability — times you switched technologies, pivoted scope, or wore multiple hats (backend plus some DevOps, for example). Understanding their business model and why you find the problem space compelling is also critical — passion signals are a real hiring filter at this stage."

{
"@type": "Question",
"name": "How should I evaluate equity when joining an accelerator-backed startup?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Standard equity grants for early startup engineers range from 0.1%-0.5% for individual contributors and 0.5%-2% for early employees (first 10 hires). Key questions to ask: What is the current valuation and implied strike price of my options? What's the fully diluted share count? How many funding rounds have there been and what's the liquidation preference stack? What is the vesting schedule and cliff? Options have a 90-day exercise window after departure at most companies — look for extended windows. Y Combinator companies typically offer 10-year exercise windows, a significant advantage."

{
"@type": "Question",
"name": "What technical skills matter most for early-stage startup engineering roles?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Early-stage startups value shipping speed and system intuition over algorithmic depth. Full-stack capability is a major plus — being able to build a feature from database schema to React component is more valuable than deep specialization. Cloud infrastructure basics (AWS/GCP/Render/Railway deployment, Docker, CI/CD) are expected. Knowledge of product analytics (PostHog, Mixpanel, Amplitude) matters because startup engineers are expected to instrument their own features. System design rounds focus on practical MVP architectures rather than Google-scale distributed systems."
