Interview Experience
The techinical aptitude test was above average level and had conceptual problem . Some good questions were there from C,C++.
persistent basically concentrates on every subject and now a days also concentrate more on software engineering.
C.C++,OS,DBMS,Computer Architecture,Networking and some microprocessor part was covered in those 60 quesn of technical.
Then 20 min for programming .Immediately after that 10 min for essay writing.
Interview Tips
Most of the times we are prepared for interview but not for technica aptitude .
The test requires sound basic knowledge of each field ,do prepare software engg questions well .At least 45+ correct questions would give chance of next round if code done is correct .
The code is evaluated only if you qualify in tech apti.
File handling program may be tough and tricky one,rest all are easy.
