2. Direct object of abstract class is not possible.
3. we need to inherit a class and make the object of derive class and can access the abstract class methods.
4. abstract classes can contains the abstract functions.

Question. can we have this definition in abstract class?

abstract class abc
abc obj;


Answer. yes, we can have same type of obj we can define in and instantiate to derive class.

Question. What pattern you used?
Singleton and facade

Question. describe the facade pattern and use in you project?
Answer. it is used to access the whole subsystem through a system. i used it in a customer class to access the subsystem like sales, billing, invoice etc.

Question. What is singleton pattern?
Answer. creating only one object of a class.

Question. How will you handle deadlock in singleton pattern?
Answer. use lock or monitor to access by single thread.

Question. What is difference between monitor.enter and monitor.tryenter functions?

Answer. monitor.enter waits for the lock until it does not get it.
while monitor.tryenter will request for lock and it return true if get the lock and return false if does not get it and process further statements.

Question. instead of creating a singleton class, suppose i create a static object of singleton class outside the class and use it though out the application, then what is use of singleton class?

Answer. singleton class is use that accidently programmer do not create the another object of the class. it is used in large systems where we expose class and functions though dlls and want to restrict programmer while using this dll do not creating multiple objects.

Question. Why forcing garbage collector to run is not recommended?
Answer. because it sometimes create performance issue and block other threads.

What is Binary Search and How to implement in C


Binary search is search mythology in a sorted list. In this process first find the middle element of list and if it is equal to the middle element its done. other wise if number is greater than the middle number search in next half otherwise search in first half with same pattern(Find the middle  element and compare).

Here is Binary search implementation in C.


#include <stdio.h>

int binary_search(int array[], int value, int size)
    int found = 0;
    int high = size, low = 0, mid;

    mid = (high + low) / 2;

    printf("\n\nLooking for %d\n", value);

    while ((! found) && (high >= low))
        printf("Low %d Mid %d High %d\n", low, mid, high);

        if (value == array[mid])
            found = 1;
        else if (value < array[mid])
            high = mid - 1;
            low = mid + 1;

        mid = (high + low) / 2;
    return((found) ? mid: -1);

void main(void)
    int array[100], i;

    for (i = 0; i < 100; i++)
        array[i] = i+20;

    printf("Result of search %d\n", binary_search(array, 44, 100));
    printf("Result of search %d\n", binary_search(array, 77, 100));

What is Difference between Overloading and Overriding


Overloading and Overriding both are example of polymorphism. Overriding is dynamic polymorphism while overloading is static polymorphism.

Overriding: Overriding is a changing of behavior of a class in drive class using dynamic polymorphism. for example in C# you have a class A  and another class B drive from A.  Class A have a virtual method abc and in class B using override you given new functionality to this method.

Overloading: Overloading is a mechanism by which we can have two different methods using same name.

Overloading can be implemented using Different parameter data types, different number of parameters, different order of parameters.

What is Intermediate Language(IL)/MSIL/CIL in .NET


IL = Intermediate Language

MSIL = Microsoft intermediate Language

CIL = Common Intermediate Language

IL, MSIL and CIL are the same thing. When we compile .NET project it not directly converted to binary code i converted to Intermediate language. And when we run the project IL is converted into binary code at run time. every language of .NET programming is converted into IL. Only some part of IL which is required at run time is converted into binary code. DLL and EXE of .NET are also in IL form.

Describe Manifest in .NET?


An assembly manifest is a text file containing metadata about .NET assemblies. The Assembly manifest contains the following things:

  1. Version of assembly
  2. Security identity
  3. Scope of the assembly
  4. resolve references to resources and classes.
  5. The assembly manifest can be stored in either a PE file (an .exe or .dll) with Microsoft intermediate language (MSIL) code or in a stand-alone PE file that contains only assembly manifest information.

What is Difference between Assembly and Namespace in C#



Namespace is logical grouping of classes. It means Namespace can contains multiple classes. Namespace can span multiple assembly. Namespace use to organize the code in a well structured manner.

namespaces can hold other types as follows:

  • Classes
  • Structures
  • Interfaces
  • Enumerations
  • Delegates


Assembly is fundamental building blocks of any .NET application. Assemblies contain metadata that describe their own internal version number and details of all the data and object types they contain. Assembly is physical grouping of logical unit.

Can We have Multiple Main Functions in C#?


Yes we can have different classes having main functions. Both class can have their own main functions. The program decides at compile time which main should be executed. So actually there is only one main function.

for example  we have two classes class1 and class2 in a program. Now how the compiler will decide which main should be executed at runtime?

using System;

class Class1
public static void Main()
Console.WriteLine("Class 1");
class Class2
public static void Main()
Console.WriteLine("Class 1");
at compile time we are specifying that Class1 is containing our Main function and that will be execute at runtime.
csc filename.cs/main:Class1

Gallup interview & Answers 2010 | Stryker Interview Questions


I gone through a Stryker First psychological interview round and here is few question i remember.

Answers are my own and you can take any other scenario and prepare.

Hi Guys,

We are sorry to inform you that we are removing the Gallup /striker interview questions. We received a mail from Gallup authority that questions are intellectual property of Gallup, Inc and we are not authorize to share in our blog. We are in the process of talking to them to find out some helpful material for Gallup preparation.

We will get back to you soon.


Here is some tips shared by Gallup Team. It will help you to clear the Gallup round:

Applicants should be themselves, honest and answer what is right for them, not what they think Gallup wants to hear. It’s about finding the right fit for the candidate and the role/company. Applicants should take the interview in a quiet place where they will not be distracted. Applicants should also be prepared for an interview that will feel different than other job interviews because the interview is structured and done over phone, applicants will not get verbal or non-verbal feedback on how they are doing.

Wish you all the best.
