Πόσο διαρκεί η διαδικασία συνέντευξης της Taboola;

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 Taboola;

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 Taboola;

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 events (e.g., page views, clicks) with timestamps, design a data structure to efficiently count the number of unique users who performed an action within the last N minutes. Assume N is large and the stream is continuous.

Taboola serves content recommendations. Imagine you have a list of articles, each with a list of tags. You are given a user's query (a string of keywords). Design an algorithm to find the top K articles that best match the query based on tag overlap. Consider efficiency for a large number of articles.

Design a system to track and report the performance of Taboola's recommendation widgets across millions of partner websites in near real-time. Consider data ingestion, processing, storage, and querying for analytics dashboards.

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

Implement a function that takes a list of Taboola campaign IDs and their corresponding bid prices, and returns the campaign ID with the highest bid price. Handle edge cases like an empty list or multiple campaigns with the same highest bid.

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

You need to implement a feature that suggests related articles to users based on their browsing history. Given a user's history (a list of article IDs they've visited) and a global index of articles and their related articles (e.g., pre-computed graph or adjacency list), design a data structure and algorithm to efficiently retrieve the top N related articles that the user hasn't visited yet.

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

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

Tell me about a time you took initiative and went above and beyond your defined responsibilities to solve a problem or achieve a goal.
