RadiSys interview questions for designations
I was interviewed in Oct 2020.
(2 Questions)
Round duration - 70 Minutes
Round difficulty - Hard
It started around 11 Am on MS teams.
There was only 1 interviewer.
The interviewer asked questions from almost every concept, whatever I mentioned in my resume.
Data Structure and Algorithms: Complete heap Sort(Full code on pen and paper), check a number is a power of 2 or not, and some follow-up questions on data structure and algorithms.
OS: Scheduling algorithms, Round Robin(implementation), Process States, and some follow-up questions on that also.
OOPS: Virtual Functions, Copy Constructors, Runtime Polymorphism, Destructors with their implementation, and lots of follows up questions on that also. They gave more focus on oops concepts in c++ only. If you know oops concepts in c++ then you should be able to explain them well with proper implementation.
Project: Complete description, Database schema(Complete diagram on paper), Data flow diagram, and which technology used in projects. My project was on spring boot based web application with proper database design. They asked many questions related to the flow of the project and request methods(POST, PUT, UPDATE, DELETE).
And some other basic questions on projects as well. The duration of this round was almost a complete hour. 7 students shortlisted after 1 round.
- Q1.

Interview Preparation Tips
Tip 1 : Try to solve implementation questions on regular basis at least 1 per day.
Tip 2 : Make a proper Roadmap to complete all the DS concepts including some advanced DS concepts also like trie. Do an ample amount of questions from every topic. IMPORTANT: Learn implementation of DS like Hashmap, heap.
Tip 3 : Minimum 2 projects. One should be the database project.
Tip 4 : You should be good in problem-solving, bits manipulation, c/c++ language, OOPs, OS, and Networking.
Tip 1 : Well Organised
Tip 2 : At least 2 projects
Tip 3 : Go through to resume of good technical students.
Tip 4 : Personally, I do not prefer any template for a resume. You can easily make on Google docs or any word editor by yourself.

- Q1. Difference between hashmap and hashset
- Ans.
HashMap is a key-value pair collection while HashSet is a collection of unique elements.
HashMap stores key-value pairs while HashSet stores unique elements
HashMap allows duplicate values but keys must be unique, HashSet does not allow duplicates
HashMap uses keys to retrieve values, HashSet does not have keys
- Q2. Tell me about yourself
- Ans.
I am a software engineer with 5 years of experience in developing web applications using Java, Spring Boot, and Angular.
5 years of experience in software development
Proficient in Java, Spring Boot, and Angular
Strong problem-solving skills
Experience working in Agile development environment
Passionate about learning new technologies
- Q3. Write a program to find a duplicate in two list (Take two list and wirte a program to print the same elementsin both list in note pad)
- Ans.
Program to find duplicates in two lists and print them in notepad
Iterate through each element in the first list and check if it exists in the second list
If a duplicate is found, print it to a notepad file
Use a hash set to store elements from the first list for efficient lookup
(4 Questions)
- Q1. What is lookup annotation in springboot
- Ans.
Lookup annotation in Spring Boot is used to indicate that a method should be cached for faster retrieval.
Lookup annotation is used in conjunction with @Cacheable annotation to cache the result of a method.
It is commonly used in Spring Boot applications to improve performance by caching frequently accessed data.
Example: @Lookup @Cacheable("books") public List
findAllBooks() { return bookRepository.findAll(); }
- Q2. What is memory management in java
- Ans.
Memory management in Java refers to the process of allocating and deallocating memory for objects in the Java Virtual Machine (JVM).
Java uses automatic memory management through garbage collection to handle memory allocation and deallocation.
Memory in Java is divided into two main areas: stack memory and heap memory.
Stack memory is used for storing primitive data types and references to objects, while heap memory is us...
- Q3. What is thread pool and what are its functions
- Ans.
A thread pool is a collection of worker threads that efficiently execute asynchronous tasks.
Thread pool helps in managing and reusing a pool of threads to execute tasks concurrently.
It improves performance by reducing the overhead of creating new threads for each task.
Thread pool can limit the number of concurrent threads to prevent resource exhaustion.
Examples include Java's Executor framework and .NET's ThreadPool cl
- Q4. Write a program to implement a stack using array
- Ans.
Implement a stack using array in a program
Create an array to store the stack elements
Implement push and pop functions to add and remove elements from the stack
Keep track of the top of the stack using a variable
