Πόσο διαρκεί η διαδικασία συνέντευξης της Pinterest;

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 Pinterest;

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 Pinterest;

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.

Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις Pinterest

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · Motivation

What interests you specifically about working on Pinterest's Ads platform, and how do you see your skills contributing to its success?

Τύπος · Algorithmic

Implement a function to calculate the click-through rate (CTR) for a given set of ads. The input is a list of events, where each event is either an 'impression' or a 'click', associated with an ad ID. CTR = (total clicks) / (total impressions). Handle cases where impressions are zero.

Τύπος · Debugging

A user reports that ads they expect to see are not appearing, while others are. The ad serving system logs show that the user is being targeted by relevant campaigns, but no ads are being returned. Debug this issue. Here's a simplified log snippet: [log snippet provided].
