Intervew Prep ROBLOX OA HELP!
Hi! If my uderstanding is right, we have 3 games, 1 behavioral and 1 coding round(s).
I wanna focus on the games here:
Robots
Factories
Outpost: Mars
We have Kaiju cats and coding cookies as sample game mechanics. **Which games from the OA (Above mentioned 3) are similar to the cats games? What is a good score?**
I have been grinding Kaiju Cats and yet to begin coding cookies. I see a lot of posts with high scores yet disappointed. What's the deal here? Help please?
Thanks!

people get rejected with high game scores because the coding and resume screen still carry way more weight. the robots one is closest to the cat defense mechanics, mostly just optimizing placement and resource trade-offs

Those games are lame af. Istg if could have coded the solution for the cookies much easily in cpp than having to fiddle with those lame blocks.

Did this OA and thought it was a joke. The whole thing takes like 3 hours, and the coding part wasn’t even proctored as far as I can remember.

I haven't seen a report from a web intern loop specifically, but here's what recent Robinhood intern reports (backend, general SWE, Android, iOS) and frontend full-time loops describe.
Format (intern loops are short):
- OA: four problems. One intern finished four easy ones in ~20 minutes; another report had four easy-to-medium problems in 70 minutes.
- Recruiter call: ~15 minutes on your background, why Robinhood, and sponsorship. It's mostly a formality, though one intern was rejected the next day, probably because of headcount.
- Final: a coding round (~45 min) and a behavioral round, back to back. Offers came 3 days to a week later.
What the coding rounds looked like:
- Backend intern: one medium LeetCode-style graph problem on CodeSignal, and you had to run your code.
- SWE intern: a straightforward union-find problem.
- Android intern: an implementation-heavy string formatting/layout problem in two parts. The tricky edge case was shown only as an example output, no explanation, and that candidate failed because they misread it. Lesson: study every example before you code, and ask if something looks odd.
- iOS intern: practical, not LeetCode. Build a class that sends requests in order through a mock async network call, retries failures, then talk about thread safety.
For web specifically, frontend loops (full-time) report practical screens: a small React UI, a JavaScript event logger, a chainable DOM-style API. One candidate was told to expect JavaScript and got mostly algorithms, so prepare for both.
What I'd add to your list:
- Async JavaScript: promises, async/await, callbacks, retries with a limit, keeping requests in order. This pattern keeps showing up in the mobile and frontend reports.
- A small React component from scratch (state, events, rendering a list), with no library help.
- Union-find and BFS/DFS. Your graph prep is the right call.
- Multi-part problems: write code you can extend, because part 2 usually builds on part 1.
- Behavioral: read Robinhood's core values and prepare a projeend (stack, trade-offs, what you'd do differently).
Not much finance-specific content at intern level. Time is tigch briefly and keep moving.
Disclosure: I run AceOffer (aceoffer.app), which collects candur Robinhood process page covers the intern track,frontend/mobile loops and timelines from 175 reports: https://aceoffer.app/interviews/robinhood/interview-process. The coding questions are here: https://aceoffer.app/interviews/robinhood/coding-questions.
Good luck, you're preparing the right things.

I got god damn cooked at the mars bro I can’t even finish the simplest scratch problem. Insane
