    Entry Level (Campus Placement) Interview

    Anonymous Interview Candidate in Jaipur, Rajasthan (India)
    No Offer
    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 2 days. I interviewed at RadiSys (Jaipur, Rajasthan (India)) in September 2016.

    Interview

    The selection process consisted of online aptitude test, 2 rounds of technical interview and HR. The online test was not very difficult. The technical interviews lasted for around 1 hour each. My first interview comprised of C, C++, DS, Basic electronics, Communication (analog and digital). In the 2nd interview I was asked only coding questions which I was not very good at. If one is really impressive in the technical inerviews then HR is not much of a big deal. However if you are not good in technical then HR takes time to discuss your flaws and it is made clear then and there that you are not selected.
