I was interviewed in Oct 2020.

Round 1 - Video Call 

(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. 

    Heap Sort Problem Statement

    Your task is to sort an array of integers in non-decreasing order using the Heap Sort algorithm.

    Input:

    The first line contains an integer 'T' denoting the number of test cas...
  • Ans. 

    Heap Sort is used to sort an array of integers in non-decreasing order by creating a max heap and repeatedly extracting the maximum element.

    • Create a max heap from the input array.

    • Swap the root (maximum element) with the last element and reduce the heap size.

    • Heapify the root element to maintain the heap property.

    • Repeat the above steps until the heap size is 1.

    • The array will be sorted in non-decreasing order.

  • Q2. 

    Ninja's Pattern with Powers of 2

    Ninja, who loves playing with numbers, sets out to arrange numbers within 'N' rows. The unique arrangement follows these rules: the first row contains 1 number, the second...

  • Ans. 

    Generate a pattern of numbers in rows following a powers of 2 sequence with numbers 1 to 9, recycling back to 1.

    • Start with 1 number in the first row, 2 numbers in the second row, 4 numbers in the third row, and so on following powers of 2.

    • Fill the pattern with numbers from 1 to 9, recycling back to 1 after reaching 9.

    • Output the pattern for the given number of rows 'N'.

    • Example: For N = 4, the pattern would be 1, 2 3, 4

Interview Preparation Tips

Professional and academic backgroundI completed Computer Science Engineering from National Institute of Technology Karnataka Surathkal.. I applied for the job as Software Engineer in BangaloreEligibility criteriaMinimum 7 CGPARadisys Corporation interview preparation:Topics to prepare for the interview - DSA, OOPS, OS, DBMS, Web Development and Networking.Time required to prepare for the interview - 6 monthsInterview preparation tips for other job seekers

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.

Application resume tips for other job seekers

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.

Interview Preparation Tips

Round: Technical Interview
Experience: questions were mainly asked on C, data structures linked lists, wireless communications. i was asked questions on pointers, linked lists, difference between structures and unions, endien-ness(big or little)
about microprocesors- interrupt scheme: which scheme is better , when?
about assembly programming.
They may ask you to write assembly codes/C program
emphasis is on the logic used and not so much on the syntax.

Tips: do C really well. they ask you about projects. also do communication subjects, microprocessors.
they prefer if you know about data structures and OS but it's okay even if you don't.
be honest. if you don't know something say you don't.
do your final year project well.

I applied via Campus Placement and was interviewed in Dec 2016. There were 5 interview rounds.

Interview Questionnaire 

2 Questions

  • Q1. Why UDP and not TCP in project
  • Ans. 

    UDP is preferred over TCP in this project due to its low latency and lightweight nature.

    • UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

    • UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

    • UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...

  • Answered by AI
  • Q2. How would you clear the 7th bit in a 32 bit register
  • Ans. 

    To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

    • Create a mask with the 7th bit set to 0 and all other bits set to 1

    • Perform a bitwise AND operation between the register and the mask

    • Store the result back in the register

Interview Preparation Tips

Round: Test
Experience: Questions were based on C concepts, given piece of code, find error, output, etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Tips: Practice aptitude, C, data structures (geeksforgeeks.org is a good source).
Duration: 1 hour
Total Questions: 30

Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked about that, details like what fields did you use in that structure, why this implementation and not some related other. Memory management, network communications, operating systems. Then questions on C concepts like memory allocation, function pointers, then data structures like linked lists, then bit manipulation in registers. Questions from electrical coursework. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Be thorough with C (know your Kernighan & Ritchie) and be prepared to go into details about your projects.

Skills: C, Data Structures, Coursework Understanding, Project And Internship

Interview Questionnaire 

2 Questions

  • Q1. Given a blackbox with arithmetic circuits , design the logical circuits
  • Ans. 

    Design logical circuits for arithmetic circuits in a blackbox.

    • Understand the functionality of the arithmetic circuits in the blackbox.

    • Identify the inputs and outputs of the blackbox.

    • Design logical circuits using logic gates to replicate the arithmetic operations.

    • Test the logical circuits to ensure they produce the same outputs as the arithmetic circuits.

  • Answered by AI
  • Q2. Embedded c-code for recursion
  • Ans. 

    Recursion in embedded C-code allows a function to call itself, useful for repetitive tasks or complex algorithms.

    • Ensure proper base case to avoid infinite recursion

    • Use stack space efficiently as embedded systems have limited resources

    • Avoid recursive functions with deep call stacks to prevent stack overflow

    • Example: Recursive function to calculate factorial of a number
