Πόσο διαρκεί η διαδικασία συνέντευξης της Grammarly;

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 Grammarly;

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 Grammarly;

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.

What interests you about working at Grammarly, and how do you see your skills contributing to our mission of improving communication?

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

Implement a data structure that can efficiently store and retrieve all unique suggestions Grammarly has made for a given user across all their documents. The structure should support adding a new suggestion and querying for all suggestions made for a specific user.

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

Design the backend system for a new Grammarly feature that suggests alternative phrasing for sentences. Consider how users will submit text, how suggestions will be generated (assume a model exists), and how results will be returned efficiently, especially for long documents.

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

Design the database schema to store user feedback on Grammarly suggestions (e.g., 'helpful', 'not helpful', 'incorrect'). The system needs to support querying feedback for specific suggestion types, specific users, and overall trends.

A user reports that Grammarly occasionally misses obvious spelling errors in their emails. Here's a simplified version of the code that handles spell checking. Find and fix the bug.

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

Given a large corpus of text and a user's writing, find the top K most similar sentences in the corpus to the user's sentences, based on a semantic similarity metric (you can define a simplified metric).

Tell me about a time you had to influence a cross-functional team (engineers, designers, marketers) to adopt your product vision or strategy when there was initial resistance. What was the situation, what did you do, and what was the outcome?

Η ζώνη κινδύνου: Κορυφαίοι λόγοι που οι υποψήφιοι αποτυγχάνουν

Με βάση τη βάση δεδομένων μας με αποτελέσματα συνεντεύξεων Grammarly, αποφύγετε αυτές τις συνηθισμένες παγίδες:

Not defining clear criteria for what constitutes a 'detectable' error within the stream.
Implementing a overly simplistic heuristic that doesn't capture nuances of writing quality.
Ignoring potential bottlenecks in suggestion generation or retrieval.
Introducing new bugs while attempting to fix the original one.

Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις Grammarly

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · Problem Solving

Describe a situation where you faced a significant, unexpected obstacle in a project you were managing. How did you approach the problem, what steps did you take to overcome it, and what did you learn from the experience?

Τύπος · String Manipulation

Write a function that takes a piece of text and returns a 'confidence score' between 0 and 1, indicating how likely the text is to contain a writing error. This score should be based on heuristics like sentence length, complexity, and presence of certain keywords (you can define these heuristics).

Τύπος · Algorithmic

Given a stream of sentences, design an algorithm to detect if any sentence contains a grammatical error that Grammarly's core product would flag. You can assume access to a hypothetical API that returns true if a sentence has a specific type of error.
