GreyOrange came to our campus around the month of November-December.
Round 1 OA The first round was an online assessment consisting of 10-15(not exactly remember) MCQs based on Object Oriented Programming in Java and one simple coding question in Java. I cleared this round and was selected for interviews afterward.
Round 2 Technical Interview I am listing down as many questions as I could remember were asked in this round: Difference between C and C++. Difference between Machine Learning and Deep Learning. Define OOP. Their types. Explain them. Difference between linked list and array. Define enumeration. What would I do if I wanted to check if the company's telephone is working properly or not? Difference between primitive and dynamic data types. Difference between function overriding and overloading.
Coding Question 1: Check if the given string is palindrome or not.
Coding Question 2: Check whether an input year is leap year. These were the simple questions asked. She grilled me on CS fundamentals and asked about 25-30 questions. This round went for 35 minutes and cleared this round pretty easily.
Round 3 Technical Interview After round 1 was over, those who got selected for Round 2 received interview links for this round after 30 minutes. The interviewer was not impressed that my expertise was C++ and not Python. He directly asked me why I chose this language or what is the reason behind choosing this language. This information is important that their company predominantly works with Python so me using C++ was a disadvantage. I assured them that I was learning Python as I wanted to dwell into Machine Learning and AI. So the questions asked in this round were: Explain Software Development Life Cycle. Explain waterfall model. Difference between SQL and MySQL. Then there were other CS fundamental questions which I was able to answer.
Coding question 1: Print all the subsequences of a given string of length 2. There was another coding question which I cannot not remember. Then he asked me if I had experience working with Linux operating system. Then asked to name a few Linux commands. He also asked to name some Linux commands used for string manipulation, which I could not answer. Overall, I think I could not answer 2-3 questions. The margin for error is really low when the competition is high. This round also went for 35 minutes.

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.
