Commavault visitó nuestro campus para reclutar para roles SDE (C++/JAVA) y SDET (PYTHON) . Si elige el lenguaje como C++/JAVA , se le asignará un rol SDE y para los roles SDET de python.
Primera ronda: ronda de codificación en línea en su plataforma. La cámara web está encendida. Hubo 15 MCQ y 3 preguntas de codificación. MCQ se basó principalmente en OOP y una pregunta de codificación fácil y dos medianas.
No recuerdo basado en xor.
Segunda Ronda: Implementación del Sistema de Archivo Virtual.Tenemos que completar su código del sistema de archivos virtual. Esta ronda fue de 6 hrs. Todo este código debía completarse en 6 horas.
