- Q2. Can you explain the internal working of a hash map in Java?
- Ans.
HashMap in Java is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to find the index in the array where it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
Retrieving a value involves hashi...
- Q3. Why do we need to override the equals and hashCode methods in Java?
- Ans.
Overriding equals and hashCode methods in Java is important for proper object comparison and hashing.
Equals method is used to compare two objects for equality, while hashCode method is used to generate a unique integer value for an object.
By overriding equals and hashCode methods, we can ensure that objects are compared based on their actual content rather than memory address.
This is crucial for collections like HashMa...

Technical Interview round with questions based around Java.
- Q1. How can you print even and odd numbers in increasing order using two threads in Java?
- Ans.
Use two threads to print even and odd numbers in increasing order.
Create two threads, one for printing even numbers and one for printing odd numbers.
Use a shared variable to keep track of the current number to be printed.
Synchronize access to the shared variable to ensure correct ordering of numbers.
Use a loop in each thread to print the next number and update the shared variable.
- Q2. What is the internal working of a CopyOnWrite ArrayList?
- Ans.
CopyOnWriteArrayList creates a new copy of the underlying array whenever an element is added, modified, or removed.
CopyOnWriteArrayList is thread-safe and suitable for scenarios where reads are more frequent than writes.
Adding, modifying, or removing elements in CopyOnWriteArrayList creates a new copy of the underlying array, ensuring thread safety.
Iterators on CopyOnWriteArrayList operate on the original array and do
- Q3. What are the differences between Synchronized Collection and Concurrent Collection in Java?
- Ans.
Synchronized Collection is thread-safe but may have performance issues, while Concurrent Collection is optimized for concurrent access.
Synchronized Collection uses synchronized keyword to achieve thread-safety, while Concurrent Collection uses non-blocking algorithms like CAS (Compare and Swap).
Synchronized Collection locks the entire collection during modification, leading to potential performance bottlenecks, while C...

Interview Preparation Tips
Experience: The company came to our campus on day 3 and agreed to take walk-ins.
Therefore resume shortlisting was the procedure.
They had a cut off of 7 CGPA.
Tips: It would be good if you have some coding background with few projects. It could anything from class projects to your internships, extra-curricular or final year projects. Don't forget to mention what all programming language you know on your resume.
Round: Technical + HR Interview
Experience: The first round consists of two panels. One of them was asking HR. And the other was asking technical questions. They were just looking whether you have the basic technical knowledge and if given an offer you will join or not.
Tips: For technical knowledge, you can refer OOPs basic concepts, standard coding interview problems, geeksforgeeks, cracking the coding interview by Laxman Gayle etc. It would be better if you can first practice hr questions among your friends instead of going directly to interview. I found a youtube channel explains technical relatively easier and simpler way. you can follow that. Just try to show that you are interested in that company.
For HR questions, one can prepare from 64 HR questions.
For the basic OOPs concepts, one can read first 10 chapters from E.Balaguruswamy but any other OOPs book will also be fine.
Confidence is the key ace any interview!!
Round: HR Interview
Experience: This round was mainly to check your personality. He was trying to know whether you will fit in the company or not. Most of the question was from my personal life. They will see whether you are serious about your life or not.
Tips: Be ready to give them instances of your life where you did things differently. Try to show that you are passionate about the company. Try to show you have a clear vision in your life and working hard to achieve that.
Round: HR Interview
Experience: This round was just a formality. The HR from the second round interview introduced me to the third interviewer. He asked few question related to the family.
Tips: One important thing I would like to is that NEVER ASSUME THAT WHATEVER YOU TOLD TO YOUR PREVIOUS INTERVIEWER WILL BE KNOWN TO THE NEXT INTERVIEW. So, if you think some specific points will help you do good in an interview...just let him know. I could be anything your project, conference, paper presentation or your past life as well.

Interview Questionnaire
4 Questions
- Q1. One coding question.
- Q2. Questions on Data Structures
- Q3. Logical Question: You are a captive. If you say the right answer, the assasin will hang you, if you say the wrong answer, he will shoot you. How do you escape?
- Q4. Other aptitude questions
Interview Preparation Tips
Experience: One year since I took the interview, so no idea exactly what questions they asked. But I was asked to write the code on paper in front of him and was asked to debug it. Some puzzles and aptitude questions along with other basic coding questions. It was great that the guy was interactive and started asking about my projects and college life.
Btw the answer to the logical question is: I should say " you will shoot me". Paradoxical.
Tips: Feel free to ask anything that you would like to know from them. Also frankly say that you don't know a certain topic if you have no clue what it is about. They don't like people wasting their time.
Round: HR Interview
Experience: This was not exactly a technical interview. He asked me to write a code to find the day of week when a certain date in any year of the calendar is given. I answered it and then he starting asking general questions as to why do u want to join the company, etc.
I gave answers to most of them convincingly. But I kept him engaged by explaining my life at college, the extra curriculars I did at college. Also I asked him about his experience as a software engineer. I asked him to reflect upon his career and how I should approach about my career.
Tips: The best part about HR interviews is they expect you to ask them lots and lots of questions. The more they are engaged, the more are your chances of impressing and getting selected. And more importantly, ask the interviewer about his experience with the present firm. This also works with my manager when ever he has a one on one with me :P
Cheers and all the best.
