Πόσο διαρκεί η διαδικασία συνέντευξης της Roblox;

Οι περισσότεροι υποψήφιοι ξοδεύουν 4 έως 8 εβδομάδες από το screen recruiter μέχρι την προσφορά. Το ίδιο το onsite loop τρέχει σε μία μέρα ή χωρίζεται σε δύο μισές ημέρες, με debrief και προσφορά τυπικά μέσα σε 5 εργάσιμες ημέρες μετά.

Πώς πρέπει να προετοιμαστώ ειδικά για την Roblox;

Εστιάστε σε τρία πράγματα: (1) στο DNA της εταιρείας που δείχνεται παραπάνω — τι βαθμολογούν πραγματικά, (2) στους γύρους του loop σας, ειδικά τον γύρο που οι περισσότεροι υποψήφιοι υποτιμούν, και (3) σε εξάσκηση στους τύπους ερωτήσεων αυτού του οδηγού χρησιμοποιώντας ένα δομημένο πλαίσιο όπως CIRCLES ή STAR.

Ισχύει αυτό για ρόλους engineering ή design στην Roblox;

Το DNA παραμένει το ίδιο — αυτό που αλλάζει είναι ο συνδυασμός γύρων. Οι υποψήφιοι SWE αντιμετωπίζουν coding screens αντί για Product Sense· οι designers αντιμετωπίζουν portfolio reviews και ασκήσεις σχεδιασμού. Το «τι εκτιμούν» και τα συμπεριφορικά σήματα μεταφέρονται σε όλες τις λειτουργίες.

Given a stream of user interactions on the Roblox platform (e.g., 'user_id', 'event_type', 'timestamp', 'item_id'), design a data structure to efficiently track the top K most frequently interacted items in the last N minutes.

Type: Data Structures. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Imagine you need to implement a feature that suggests friends to users based on mutual connections. Given a list of friendships (pairs of user IDs), write a function to find all users who have exactly K mutual friends with a given target user.

Type: Algorithms. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

How would you design a system to handle real-time analytics for millions of concurrent users playing Roblox experiences? Focus on data ingestion, processing, and querying for dashboards.

Type: Scalability. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Implement a function to find the shortest path in a 2D grid representing a Roblox game level, where some cells are blocked. The path can only move horizontally or vertically, and each move has a cost. Consider that certain cells might have different movement costs.

Type: Algorithms (Hard). Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

A user reports that their custom avatar accessory is not displaying correctly in certain experiences, sometimes appearing distorted or missing entirely. Here's a simplified version of the rendering code. Debug and fix the issue.

Tell me about a time you had a significant disagreement with an engineer or designer about a product decision. How did you approach it, and what was the outcome?
