RadiSys Software Engineer Interview Questions and Answers

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.
