I recently appeared for the recruitment process of OpenXcell through an on-campus drive at my college.
Round 1: Aptitude and Computer Fundamentals
The first and only round I attempted was an online test that comprised questions from two major sections:
Aptitude (Quant + Logical Reasoning)
Computer Fundamentals (CS basics like DBMS, OS, CN, OOPs, basic coding concepts)
The overall difficulty level of the test was easy to moderate. Most of the questions were straightforward and based on basic concepts. A few questions in computer fundamentals required deeper understanding, but nothing too tricky.
