Hi , ppl i am having 6 months exp in development and has also completed software quality testing analyst course from SQTL and looking for job in testing.

Hi friends,
Its great working at Verizon. They give u lot of recognition.Got offer when i am in my final year in college.
Interview was not so tough.Htey give more importance to clearing the test.It includes basics of C/UNIX/ OS etc. Also i had option to choose to answer either C++ or JAVA questions in the test.
They give more importance to technical interview than HR. So if u perform well in Technical round u r sure of gettting through.
Mostly they ask basics from C/C++ and u can tell about your final year projects.
It is better if u have done mini Software projects. U can confidently wxplain. U can restict them from asking more, by telling more.So try to showcase your full capabilities.

I interviewed twice already with Verizon. First, a twenty minute phone interview, then a 2 hour computer test, and I go in today for my final interview. So far the process was cake, I’ll keep you posted as to the details of todays interview!

Few Questions were a little confusing….

Sample Code

{
protected double mySalary;
public double Salary {
get { return mySalary; }
set { mySalary = value; }
}

}

public sealed class Manager : Employee
{
private double myBonus;

get { return myBonus; }
set { myBonus = value; }

Interview 2 -
This interview was a bit longer and I found it a bit difficult.

1) Oops Concepts definitions. There practical Application. Difference between Data Hiding and Encapsulation.

2) What are Cursors and when are they used.

3) Data Stuctures and there practical Application in the industry. Like B.Trees in SQL Server indexing.

4) What is the difference between a normal Button and a SUBMIT button.

5) Can we have more than one form in a single HTML Page.
