J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 1 jour. J'ai passé un entretien chez Ciena (New Delhi) en oct. 2025
Entretien
On Campus Oppurtunity. OA consisted mostly of fundamental questions on C++, OS, CN, Linux and Aptitude. Interview consisted of basic DSA questions and strong grip on C++ (pointers, OOPs, memory management). Also my project was OS related so many questions were around my project.
