Πόσο διαρκεί η διαδικασία συνέντευξης της Cisco;

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 Cisco;

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 Cisco;

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.

Why are you interested in a Software Engineer role at Cisco, specifically within our Enterprise Networking division?

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

Given a list of network device configurations (represented as strings), write a function to find all devices that have a specific configuration parameter set to a given value. For example, find all devices where 'VLAN' is set to '10'. Assume configurations can be complex and nested.

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

You are given a stream of network traffic data, where each data point includes a source IP, destination IP, and timestamp. Design an algorithm to detect potential denial-of-service (DoS) attacks by identifying IP addresses that are sending an unusually high number of requests to a specific destination within a short time window.

Design a system for real-time network traffic monitoring and anomaly detection for a large enterprise network. Consider how to collect data from thousands of devices, process it efficiently, and alert administrators to potential security threats or performance issues.

You are given a function that simulates packet loss in a network. The function is supposed to return the number of packets successfully delivered, but it has a bug. Debug and fix the function. Assume the function takes the total number of packets sent and a probability of loss for each packet.

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

Implement a Least Recently Used (LRU) cache suitable for caching network device states or configurations. The cache should support `get(key)` and `put(key, value)` operations, evicting the least recently used item when the cache is full.

Η ζώνη κινδύνου: Κορυφαίοι λόγοι που οι υποψήφιοι αποτυγχάνουν

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

Focusing only on salary or title without mentioning technical interest or company mission.
Not clearly articulating their specific actions and contributions.
Describing an unresolved conflict or a situation where they simply gave in.
Not handling different hardware/software versions and compatibility issues.

Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις Cisco

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · Algorithmic

Implement a function that takes a Cisco IOS-like command string (e.g., 'interface GigabitEthernet0/1', 'ip address 192.168.1.1 255.255.255.0') and parses it into a structured representation (e.g., a dictionary or object) that identifies the command and its arguments.

Τύπος · Influence

Describe a situation where you had to influence a stakeholder (internal or external) who was resistant to your recommendation. How did you approach it?

Τύπος · Conflict Resolution

Tell me about a time you had a significant disagreement with a colleague or manager. How did you approach the situation, and what was the resolution?
