Think of these building blocks as objects, and each object has its own unique features and actions. These features and actions are defined by a template called a class. So, in OOP, we create these objects based on classes to build our programs. What is Abstraction? What is the difference between overloading and overriding? What are the various types of constructors in C++? What is virtual function? What is an abstract function? What is compile time polymorphism? What is encapsulation in Java? What is an abstract function? What are the differences between class and object? What is composition? GreyOrange Interview Questions on OS An Operating System(OS) is software that manages and handles the hardware and software resources of a computer system. It provides interaction between users of computers and computer hardware. What's the difference between Semaphore and Mutex? What is Belady’s Anomaly? What is cache? What is the Batch Operating System? What is IPC? What is Context Switching? What is Banker's Algorithm? What is Demand Paging in Operating System? What is deadlock? What is Spooling ? GreyOrange Interview Questions on Computer Networks A computer network is a collection of computers or devices connected to share resources. Any device which can share or receive the data is called a Node. Through which the information or data propagate is known as channels, It can be guided or unguided. What is a Socket in Computer Network? What are the various Types of Network Topology? What is IP Spoofing? Explain the purpose of DNS and how it works. Explain the concept of load balancing. What's the difference between Bluetooth and wifi? What is an IPv4 address? Define piggybacking? What is the FTP protocol? What is the ARP protocol?

About Greyorange Interview Reports
This question was reported by a candidate who interviewed at Greyorange. 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 Greyorange are the higher-signal extractions to take from this report.
For broader preparation context, the Greyorange 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 Greyorange reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Greyorange 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 Greyorange 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.
