This is the main question in 2 business rounds, your ans 
will make u go to next level. be sure u hav done gud 
reaearch on company, and show them what they and and what 
you have for them.

do some gud homework, know ab't company surrent business 
status and dont forget to attend the induction program on 
the day of interview as the 80% questions for business 
round will be from that.

first check with the Scheme provided, if you have scheme 
you can make use to serialise it.

The person will look for the technical feasibility and 
solution providing strength and your way of explanation. 
dont get stuck any where, shuld be very fluent using the 
technical terms and sametime shuld be thoughtful in 
understanding the requiement. 

The business rounds goes in the same way, asking you to 
explain your projects, architechture, DFD's protypes and 
other things.

the main points he will be looking is your architechture, 
DFD's and Page flow. be sure to use technical terms in your 
explanation coz the interviewer will be more keen on your 
terminalogy rather than the project you have done.

its simple for guys 4m Engineering background.
if u have an idea with series of numbers, (n(n+1)/2)

first take the sum of all the objects in array, next 
subtrat the sum of arrays after deletion of object. this 
will give you the deleted object value.

1,2,3... 10; sum = 10(10+1)/2=55

suppose the value of object deleted is 6;

then sum of the array after deletion will be 49;

55-49=6 ANS:

That will throw an error coz in the second function the 
return type is double and result will be in double. to 
rectify it we need to convert the second function result as 
double, then the code executes correctly.

it will throw an error because the function overloading is 
acheived by
1) changing the number of parameters
2) changing the order of parameters of different datatypes

we can't acheive function overloading by changing the 
return type

it will throw compile error because of same parameter's 
data type in second overloaded function.

A delegate object encapsulates a reference to a method. In 
C++ they were referred to as function pointers.

Example:

select col1 from table_name where 
(( convert(DateTime,Date_Column1,102) between coalesce
(@Date_Column1,convert(DateTime,Date_Column,102)) and 
coalesce(@Date_Column2,convert(DateTime,Date_Column,102))))

//Date_Column: Column in the Table
//Date_Column1: first value of date range
//Date_Column12: second value of date range

It’s an abstract class with public abstract methods all of 
which must be implemented in the inherited classes. 

Explain him if you have ever developed an interface.

The CLR is the execution engine for .NET framework 
applications.
Commom Type System. This is the range of types that .NET 
runtime (CLR)
understands.
Commom Language Specification. This is the subset of CTS, 
which all .NET
languages must support.

CTS,CLS are the componets of the CLR
CLR: is use for execute msil code to native code
CTs :is Common type System    Contains Set of common data
types that are common to all dotnet langauges
Itis check all type checkin for interoperatibility comman to
all language.
CLs is common langauge specification contains rules that are
to be followed for .net frame work  supported languages

Function, Constructor, Operater overloading comes under 
compile time polymorphism and function overriding, virtual 
functions come under runtime polymorphism.
