Πόσο διαρκεί η διαδικασία συνέντευξης της Flix;

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 Flix;

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 Flix;

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.

You are given a list of user booking events, each with a timestamp and a user ID. Write a function to find the number of unique users who booked a ticket within any 1-hour window. For example, if users A, B, and C book within the same hour, that counts as one instance. If later, users D and E book within another hour, that's a second instance.

Design a real-time bus tracking system for Flix. Users should be able to see the live location of their bus on a map, and receive notifications about delays or arrival times. Consider scalability for millions of users and thousands of buses.

Design a system to recommend bus routes or destinations to users based on their past bookings and browsing history. How would you handle cold starts for new users?

A user reports that sometimes, when they search for routes, the results are incorrect or missing. Here's a simplified version of the route searching code. Find the bug and explain how to fix it.
