Avaya visited our college for campus hiring.The selection process was as follows:- 1 - Aptitude test Avaya had own platform for Aptitude test. It had 50 mcqs - 25 questions in technical and 25 in non technical section. MCQs were mainly based on basic maths, logic, Computer Science , c++ concepts. Time duration was 1 hr. Questions were easy. 16 people were shortlisted for interview. 2 - Tech interview 1 Questions were as follows:-
Solution to Dining Philosophers problem. Difference between mutex and semaphore Questions about critical section Explain normalization in DBMS with example. Write SQL query to find top 2 performers in a test. Explain different phases of compiler,which data structure can be used for symbol table. Some basic linux commands Questions related to hashing , hash function calculation, significance of hashing, Different techniques for collision resolution in hashing. Explain inheritance and abstraction with examples. Questions related to compile time and run time polymorphism Program 1- Insert node in doubly linked list Program 2- Check whether a singly linked list is palindrome or not Puzzle- There are n number of coins. All the coins have same weight except one.How to find that coin? Then some of us were called for 2nd technical interview 3 - Tech interview 2 They asked me which language I am comfortable with.I chose java . Questions were as follows:- Brief discussion of project work done during Internship and questions based on that Questions based on string literal pool concept and immutable class in java. How will you implement own immutable class Questions related to singleton class Questions related to static binding and dynamic binding. Checked vs unchecked exceptions Question related to serialization Interface and abstract class difference Program 1 - A square matrix of integers is given. In each row and column, integers are sorted in descending order . Some of the integers are -ve. How to find number of -ve integers in minimum time? Puzzle - Switching 100 light bulbs puzzle 4 - HR interview General Questions on family background, extra curricular activities, why Avaya?,what are your future plans? Finally they selected 4 people and I was one of them. Thanks a lot to GeeksforGeeks !!

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