Opal-RT Technologies Software Developer C++ interview questions

I only got the technical interview on the phone, basic question where ask, what is your experience in C++ programmation, why do you want to work here, what do you know about our product, then they send me a link via email to do an programmation test while still been on the phone with the interviewer.

Only few techincal quesions and human questions, they were 3 people working together, two RH persons and technical director asking questions, but they were really nice and it was really unstressful interview.
