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.

tech 1 :
my project was in AI so related questions first ,he wanted a basic intro of all.

so i couldnt do it then he asked whether i need another vessel and asked how much quantity ,i told 5.
he said consider it ,did it in seconds and so he again said that was way easy now do original problem .
I tried a lot he kept talking on mobile for 5 min (worst part).
I : so he asked me again some question on queue ,its implementation
I : then went to OS ,priority queue scheduling basic idea and code.
So i am finished with you .said thank you sir .

Interview Experience
TECH 2:
I : so shivshankar introduce yourself.
I : What are all these sites and ranks ,explained him in detail .
I : area of intrest asked i told DS.
