CSC PAPER & INTERVIEW - COIMBATORE & Vijayawada

The Whole process of selection involved 5 stages:
1. General Aptitude
2. Technical Aptitude
3. GD
4. Technical Interview
5. HR Interview

I. General Aptitude (40 Qs, 40 mins)
This Section involved aptitude questions such as the following

1. Sudoku. you need to fill-up the table using the hint (addition of row, column, diagonal =15) and available cell values. its easy. if you figure it out, you can answer five questions correctly.
