Interview Preparation Tips
Experience: Aptitude test was taken on aspiring minds and name of the test series was AMCAT.600 students gave the exam and 90 were selected for the GD.
There were four sections and each section had a minimum number of questions to be attempted and there was no negative marking.Navigation among questions and sections were not allowed so use you time and mind carefully.
Section 1 - Quants
Section 2 - Verbal Ability and Critical Reasoning
Section 3 - Logical Reasoning
Section 4 - Programming and Computer Science
Tips: Speed is the key.key. Quants are easier they test only the speed of the candidate.I think the programming section has the max weight age so try to focus on that section and try to score maximum marks in that section. Programming questions were tough and there were questions from a wide range of subjects Networking , Algorithms ,Data Structures , Java, C/C++, Operating Systems,Advanced Databases etc.
Round: Group Discussion
Experience: Group discussion was very ordinary and easy to crack if you have the right content and suitable examples and clear and crisp communication skills.I took the against side of the issue which only 2 out of 10 members did and I was very bold and effective with my statements and defended my stance effectively.
Tips: Give examples,Be bold and clear and crisp .
Duration: 25 minutes
Round: HR Interview
Experience: My HR interview started at around 11pm in the night so it was very chilled out.He asked me about what excites me , why verizon , what projects I have done and what role I've played it them.He asked about my college life ? What do we study ? Why do you want to work for a MNC rather then a startup? and many more general questions which I don't remember because my interview was very chilled out. I was having fun.I asked him a lot of questions about job profile and company and many of their products so he was impressed with me.
Tips: Please do a detailed survey of the work that the company does and have knowledge about the sector and SDLC.
Round: Puzzle Interview
Experience: I was given a 3*3 and 5*5 magic cube to solve.I tried a lot of times and it took nearly 15-20 minutes to solve both the questions correctly.He asked my approach I said politely Hit and Trial and then he said to me there's a shortcut and he told me a very nice and quick trick to solve the magic cube.
Round: Technical Interview
Experience: Basic programming questions were asked about patterns, strings and some algorithms like quick sort and merge sort.
Major tough and difficult questions were asked on databases and advanced databases in oracle.He asked many questions about the projects that I've done.In depth questions regarding projects were asked.He asked questions about various things used in web application and may question regarding MySql and Tables and JOINS.
Tips: Keep your calm even if you don't know any answer. I couldn't answer to one question of databases which carried our discussion on that questions for around 10 mins but still I couldn't answer the question and in the end I asked just out of curiosity that I want to know the answer to the question and he explained me the concept perfectly.

7 Questions
- Q1. Array sorting – Bubble sort and its complexity?
- Ans.
Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Bubble sort has a worst-case and average complexity of O(n^2), where n is the number of items being sorted.
It is not efficient for large lists and is generally used for educational purposes.
Example: Sorting an array of strings in alphabetical order using bubble sort.
- Q2. Various storage classes in C? Difference between auto, static?
- Ans.
Auto and static are two storage classes in C. Auto variables are local to a function while static variables retain their value between function calls.
Auto variables are created when a function is called and destroyed when the function ends
Static variables are initialized only once and retain their value between function calls
Auto variables have garbage value if not initialized while static variables are initialized to

Interview Preparation Tips
Experience: The written test had 75 questions and we were allotted 80 minutes for the same.There were four sections: Verbal, Analytical, Attention to Detail and Technical (C and Data Structures).First, there was the verbal section. Basically, questions on articles, synonyms and antonyms were asked. Two passages were also given and related questions were asked. The analytical section included questions from quant (set theory, data sufficiency, cubes,etc.) and Logical Reasoning.
The third section was the easiest and did not require any special preparation. From a group of patterns, we had to determine if they were alike or different.
The fourth was the technical section and had 5 questions each from C and DS. This was the toughest section.Time management is absolutely important. There were sectional cutoffs and so we had to clear each section.
Round: Technical Interview

10 Questions
- Q1. All project related questions .(He found some fault and asked to remove it)?
- Q2. Why do we need garbage collection and how it is done in JAVA ?
- Ans.
Garbage collection is necessary to free up memory occupied by unused objects. Java uses automatic garbage collection.
Garbage collection helps prevent memory leaks and improves performance.
Java uses a mark-and-sweep algorithm to identify and remove unused objects.
The JVM periodically checks for unused objects and frees up memory occupied by them.
Developers can also manually trigger garbage collection using System.gc() m...
- Q3. Difference between TCP and UDP ?
- Ans.
TCP is a connection-oriented protocol while UDP is connectionless.
TCP provides reliable data transfer while UDP does not guarantee reliability.
TCP uses flow control and congestion control while UDP does not.
TCP is slower than UDP due to the overhead of establishing and maintaining a connection.
UDP is faster than TCP for applications that can tolerate data loss such as video streaming or online gaming.
- Q4. In which scenario do we need UDP ?
- Ans.
UDP is used in scenarios where speed is more important than reliability, such as online gaming and video streaming.
UDP is a connectionless protocol that does not guarantee delivery of packets
It is faster than TCP because it does not have to establish a connection before sending data
UDP is commonly used in online gaming, video streaming, and VoIP applications
It is also used for broadcasting and multicasting data to mult
- Q5. Discussion on Hashmap , Collision function , heap data structure
- Q6. Two puzzles a. Given a bar , cut it twice and pay for 7 days?
- Q7. B. three ants are running on edges of a equilateral triangle with same speed. What is prob that dey will never meet?
- Ans.
The probability that three ants running on the edges of an equilateral triangle will never meet is 1/3.
The ants will never meet if they all move in the same direction (clockwise or counterclockwise) at the same speed.
The probability of this happening is 1/3, as each ant has two possible directions to choose from.
Example: If one ant starts moving clockwise, the other two ants must also move clockwise to never meet.
- Q8. Tell me about yourself ?
- Ans.
I am a software developer with experience in Java and Python.
I have a Bachelor's degree in Computer Science.
I have worked on various projects involving web development and data analysis.
I am proficient in Java and Python programming languages.
I am a quick learner and enjoy working in a team environment.
