Recently I applied to Barracuda Networks and following is my experience.
Round 1 It was a 1 hour duration paper consisting of questions from C/Computer Networks/Operating System/Puzzles. Most of the C questions were regarding the Output of given code. Round 2 (Technical Interview): In this round I was asked : Linked List questions Puzzles 1: (x-a)*(x-b)......(x-z) = ? ans: 0 as (x-x) is one of the terms 2: abc +abc +abc = ccc (ans: a=1, b=8, c=5) Program to print patterns For n=3 (so I had to write code for general n) * * * * * * * * Then he moved on to my projects. Round 3 (Technical Interview) Some C output programs. Puzzle of measuring 4L from 3L and 5L jars Find a 10-digit number where the first digit is how many zeros in the number, the second digit is how many 1s in the number etc. until the tenth digit which is how many 9s in the number. Questions related to Operating System concepts (threading, caching, scheduling) Networking (like how does ping work, how did LAN function etc) Addressing schemes in computer system. Round 4 (HR) It was just to get to know you. In case you have any other offers. How soon can you join? Why didn't you join the other company from which you had offer? Round 5 (taken by MD) If you've made it till here, you're almost done. Questions about my strengths, weaknesses, why should we hire you etc. Why I didn't join the company I had offer from? Then he explained about the different profiles in the company.

About Barracuda Networks Interview Reports
This question was reported by a candidate who interviewed at Barracuda Networks. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Barracuda Networks are the higher-signal extractions to take from this report.
For broader preparation context, the Barracuda Networks interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Barracuda Networks reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Barracuda Networks Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Barracuda Networks reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
