Interview preparation tips for other job seekers - Get some knowledge & start working, so that you are not going to face the heat

Round: Test
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.
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.

S : told him about A* algo,fleming bird algo,salesperson problem .(took lot of time)
I : explain me this project
S : told him some of conditions as all were not possible ,some talk on optimization of length of code etc.
I : So tell me about programming sites
S : told them all about codechef,hackerrank,spoj.
I : Now say i have char ch='n' my name starts with n say how will it get stored
I : so what all microprocessor has
I : how many type of interrupts , and in detail eg (I wasnt sure ,gave eg but told that i was not sure)
I : implement circular link list
I : insert element in circular link list.
I : constant variables,volatile variables.
I : What are stack and queue and thier application.
I : where are variables stored (dyanmic allocation and static with the global and static varoable he wanted)
I : now here comes puzzle from nowhere : 3 cans each full with capacity 3,5,7 liter make it 5,5,5
(I thought there might be some way and kept talking every moment ,is there large supply of water ,can we spill it all he denied)
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 .
