Interviewing
Startup vs big-tech interviews
Big tech wants patterns, design frameworks and STAR stories. Startups want practical coding, take-homes and product conversation.
Prepare differently for the two tracks. Many candidates need both if they are exploring widely — budget an extra week for practical rounds.
| Dimension | Big tech | Startups / smaller companies |
|---|---|---|
| Coding | LeetCode-style common | Often practical: build a feature, debug, review a PR |
| Design | Classic distributed systems prompts | "Design the feature you'd own here" |
| Behavioral | Formal story bank | Culture and ownership in conversation |
| Take-homes | Rare (some teams still use) | Common; 2–6 hour scoped tasks |
| Leveling | Explicit ladders, committees | Title inflation; negotiate scope and equity carefully |
| Timeline | Multi-week loops | Can be days |
Concept
You already know how loops work. This page is the fork: which skills the loop actually runs.
Walking through a take-home
Time-box them. Deliver something complete and documented rather than an ambitious half-built demo. Include a short README: assumptions, how to run, what you would do next with more time.
For startups, practice reading an unfamiliar codebase, writing a small feature with tests and explaining trade-offs in a product conversation. For big tech, prioritize patterns, design frameworks and STAR stories.
The recruiter screen still matters on both tracks. Come prepared with target level range, work authorization, earliest start date and a one-minute career arc. At startups, title inflation is real — negotiate the scope of the role and the equity, not just the word "senior." Pair that with offers.
Common mistakes
- Bringing only LeetCode to a startup loop that wants a feature in their repo.
- Bringing only a take-home portfolio to a big-tech coding screen.
- Spending a weekend on an unbounded take-home. Time-box; ship a complete slice.
Check yourself
A startup sends a 2–6 hour take-home. What do you turn in?
Something complete and documented, with a README of assumptions, how to run, and what you would do next — not a half-built demo.
You are exploring both tracks. What extra time do you budget?
About a week for practical rounds: reading unfamiliar code, a small feature with tests, product conversation.
Key takeaways
- Big tech: patterns, design frameworks, STAR stories.
- Startups: practical coding, take-homes, product conversation, careful equity.
- Time-box take-homes. Complete and documented beats ambitious and unfinished.
- Title inflation at startups: negotiate scope and equity, not the sticker.
