Πόσο διαρκεί η διαδικασία συνέντευξης της Cast AI;

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 Cast AI;

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 Cast AI;

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.

Cast AI Interview Question Bank

A sample from our database, grouped by round. Sign up to see the full set.

9 of 21 questions shown

Recruiter Screen

1
Τύπος · Motivation
What interests you about Cast AI and the challenges of building a cloud cost optimization platform?

Coding Screen

2
Τύπος · Data Structures
Given a stream of Kubernetes pod events (creation, deletion, status changes), design a data structure to efficiently track the number of running pods per namespace and report the top N namespaces with the most pods in near real-time.
3
Τύπος · Algorithms
Implement a function to calculate the optimal Kubernetes resource allocation (CPU/memory) for a given workload based on historical usage patterns, minimizing waste while meeting performance requirements. Assume historical data is provided as a list of usage samples.

System Design

4
Τύπος · Distributed Systems
How would you design a distributed system to collect and process real-time telemetry data (CPU, memory, network usage) from thousands of Kubernetes clusters globally for cost analysis? Discuss trade-offs in data ingestion, processing, and storage.
5
Τύπος · Architecture
Cast AI needs to provide recommendations for rightsizing Kubernetes resources. Design the backend architecture for a recommendation engine that takes cluster state, workload characteristics, and cost data as input.
