Radisys Interview Experience | Campus Placement 2020

Round 1(Online Test): There were around 60 MCQs from different concepts like c++, java, aptitude, data structures, and algorithms. 

Around 40 students were shortlisted for interviews out of 300 students.

Round 2(Technical Interview 1): 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.

Round 3(Technical Interview 2): That was a short interview of around 30 mins. There were two members in the panel. They asked some questions about oops, os, project, segmentation fault. They give more focus on c, c++, oops concepts more.
If u write c, c++ in your resume. Then you should know in deep.

No one eliminated after round in this round.

Round 4(HR): There were also two members in the panel. They asked some basic HR questions like how was your day, how was your interview, what do you know about Radisys, did you visit our website and last do you want to ask any question.

Finally, a total of 6 students got (FTE+Intern) offers. And luckily I was one of them.

Tip: You should go through your resume properly. Whatever concepts you mentioned in the resume, you should know them well. They will ask lots of c,c++ question in both technical rounds so prepare accordingly. As I prefer JAVA, so sometimes I wasn’t able to give answers but that time they consider me.
All the best.
