THINK OUTSIDE OF THE BOX
No one will GET second chance to impress....
Very very Impressive Questions and Answers..... ...
Question 1: You are driving along in your car on a wild, stormy night, it's raining heavily, when suddenly you pass by a bus stop,
and you see three people waiting for a bus:
An old lady who looks as if she is about to die.
An old friend who once saved your life.
The perfect partner you have been dreaming about.
Which one would you choose to offer a ride to, knowing very well that there could only be one passenger in your car?
This is a moral/ethical dilemma that was once actually used as part of a job application.
* You could pick up the old lady, because she is going to die, and thus you should save her first;
* or you could take the old friend because he once saved your life, and this would be the perfect chance to ! pay him back.
* However, you may never be able to find your perfect mate again.
The candidate who was hired (out of 200 applicants) had no trouble coming up with his answer. Guess what was his answer?
He simply answered:
"I would give the car keys to my Old friend and let him take the lady to the hospital. I would stay behind and wait for the bus with
the partner of my dreams."
Sometimes, we gain more if we are able to give up our stubborn thought limitations. Never forget to "Think Outside of the Box."
Question 2: What will you do if I run away with your sister?"
The candidate who was selected answered " I will not get a better match for my sister than you sir"
Question 3: Interviewer (to a student girl candidate) - What is one morning you woke up & found that you were pregnant.
Girl - I will be very excited and take an off, to celebrate with my husband.
Normally an unmarried girl will be shocked to hear this, but she managed it well. Why I should think it in the wrong way, she
said later when asked
Question 4: Interviewer: He ordered a cup of coffee for the candidate. Coffee arrived kept before the candidate, then he asked
what is before you?
Candidate: Instantly replied "Tea"
He got selected.
You know how and why did he say "TEA" when he knows very well that coffee was kept before.
(Answer: The question was "What is before you (U - alphabet) Reply was "TEA" ( T - alphabet)
Alphabet "T" was before Alphabet "U"
Question 5: Where Lord Rama would have celebrated his "First Diwali"? People will start thinking of Ayodya, Mitila [Janaki's
place], Lanka etc...
But the logic is, Diwali was a celebrated as a mark of Lord Krishna Killing Narakasura. In Dusavataar, Krishnavathaar comes
after Raamavathaar. So, Lord Rama would not have celebrated the Diwali At all!
Question 6: How do you make a road wide?
The candidate answered, but a b (alphabet) before road to amek it broad (= wide). My relative has answered this in a Civil
Service Interview.
Question 7: The interviewer asked to the candidate "This is your last question of the interview. Please tell me the exact position
of the center of this table where u have kept your files."
Candidate confidently put one of his finger at some point at the table and told that this was the central point at the table.
Interviewer asked how did u get to know that this being the central point of this table, then he answers quickly "that sir u r not
likely to ask any more question, as it was the last question that u promised to ask....."
And hence, he was selected as because of his quick-wittedness. .........
This is What Interviewer expects from the Interviewee. ....

Will Job Hopping Damage Your Career?
Will Job Hopping Damage Your Career?
Found some interesting facts on the above topic on various sites, consolidating here…
Ram's grandfather worked in the same company his whole life. His mother labored in the same industry until she retired, though for different employers. But that kind of longevity was not for Sam and his brother, who have worked in six different career fields during 30 combined years.
Muzio, president and CEO of Group Harmonics Inc., in Albuquerque, New Mexico, says accelerated movement -- often called job-hopping -- is becoming the norm.
"Not long ago we all said that the average person changes jobs about seven times in his or her lifetime; now we say it's probably more than 10 jobs over at least five different careers," he explains.
It's a generational trend, experts say. Generations X and Y are more comfortable switching jobs every few years than their predecessors were, and as they scale the ranks of the job market, such changes are increasingly accepted and understood. But some call it a lack of commitment that's damaging to workers and employers.
The New Style of Job Search?
Some experts say frequent job changes don't mean death to your career -- they're just part of work life.
"I don't think you can be judgmental [and say it's] good or bad -- it just is; it's a fact of life in today's workplace. It's fruitless to impose a judgment on it," explains Sally Haver, senior vice president of business development at the Ayers Group in New York. "If people don't move with change, they get left in the dust."
Rich Gee, an executive career coach based in Stamford, Connecticut, agrees, and suggests finding a new term for job-hopping.
"It's just the nature of the beast of employment: Expect people to leave after two to three years, and be happy if they stick around longer," Gee says.
Brooks Savage, CEO of the Executive Staffing Group in Raleigh, North Carolina, sees it differently.
"When you don't have someone stay in a post two to three years, how do you learn? To get a degree out of college at least takes four years," he says, noting neither he nor his clients are interested in resumes of job-hoppers (people who change positions every year or so). He'll also ask candidates about any jobs where they spent less than five years.
Savage questions the commitment of individuals who don't stick around long, and says the job market could change dramatically if commitment levels don't increase.
Job-Hopping Pros & Cons
Ultimately, it's important to plan carefully when evaluating a job change and not switch too often, experts say, citing the following pros and cons:
- Pro: Pay increases. "The way you make a large jump in your pay scale is when you leave a company and go to another one. It's proven time and time again," Gee says.
- Pro: Networking. Gee says different gigs expose you to new networks of people, which can be a real asset.
- Pro: Learning new skills. New environments sometimes teach workers new skills and how to function more quickly, says Kathy Jeffery, vice president of human resources at Whitman Hart Consulting in Chicago.
- Con: Landing in a worse situation. "You might jump into a new job that's worse than your old job," Gee explains.
- Con: Moving too soon. "If you're really leaving places rather quickly you may not be extracting the full value from what that particular workplace has to offer you," notes Haver, of the Ayers Group.
The net result is, if you don't like your current job, move on! I have been there and done that! Cheers!

Simple Java Questions and Answers
The class System has a variable out that represents the standard output, and the variable err that represents the standard error device. By default, they both point at the system console. This how the standard output could be re-directed:
Stream st =
new Stream (new
FileOutputStream ("techinterviews_com.txt"));
System.setErr(st);
System.setOut(st);
2. What's the difference between an interface and an abstract class?
An abstract class may contain code in method bodies, which is not allowed in an interface. With abstract classes, you have to inherit your class from it and Java does not allow multiple inheritance. On the other hand, you can implement multiple interfaces in your class.
3. Why would you use a synchronized block vs. synchronized method?
Synchronized blocks place locks for shorter periods than synchronized methods.
4. Explain the usage of the keyword transient?
This keyword indicates that the value of this member variable does not have to be serialized with the object. When the class will be de-serialized, this variable will be initialized with a default value of its data type (i.e. zero for integers).
5. How can you force garbage collection?
You can't force GC, but could request it by calling System.gc(). JVM does not guarantee that GC will be started immediately.
6. How do you know if an explicit object casting is needed?
If you assign a superclass object to a variable of a subclass's data type, you need to do explicit casting. For example:
Object a;Customer b; b = (Customer) a;
When you assign a subclass to a variable having a supeclass type, the casting is performed automatically.
7. What's the difference between the methods sleep() and wait()
The code sleep(1000); puts thread aside for exactly one second. The code wait(1000), causes a wait of up to one second. A thread could stop waiting earlier if it receives the notify() or notifyAll() call. The method wait() is defined in the class Object and the method sleep() is defined in the class Thread.
8. Can you write a Java class that could be used both as an applet as well as an application?
Yes. Add a main() method to the applet.
9. What's the difference between constructors and other methods?
Constructors must have the same name as the class and can not return a value. They are only called once while regular methods could be called many times.
10. Can you call one constructor from another if a class has multiple constructors
Yes. Use this() syntax.
11. Explain the usage of Java packages.
This is a way to organize files when a project consists of multiple modules. It also helps resolve naming conflicts when different packages have classes with the same names. Packages access level also allows you to protect data from being used by the non-authorized classes.
12. If a class is located in a package, what do you need to change in the OS environment to be able to use it?
You need to add a directory or a jar file that contains the package directories to the CLASSPATH environment variable. Let's say a class Employee belongs to a package com.xyz.hr; and is located in the file c:/dev/com.xyz.hr.Employee.java. In this case, you'd need to add c:/dev to the variable CLASSPATH. If this class contains the method main(), you could test it from a command prompt window as follows:
c:\>java com.xyz.hr.Employee
13. What's the difference between J2SDK 1.5 and J2SDK 5.0?
There's no difference, Sun Microsystems just re-branded this version.
14. What would you use to compare two String variables - the operator == or the method equals()?
I'd use the method equals() to compare the values of the Strings and the = = to check if two variables point at the same instance of a String object.
15. Does it matter in what order catch statements for FileNotFoundException and IOExceptipon are written?
A. Yes, it does. The FileNoFoundException is inherited from the IOException. Exception's subclasses have to be caught first.
16. Can an inner class declared inside of a method access local variables of this method?
It's possible if these variables are final.
17. What can go wrong if you replace && with & in the following code:
String a=null;
if (a!=null && a.length()>10)
{...}
A single ampersand here would lead to a NullPointerException.
18. What's the main difference between a Vector and an ArrayList
Java Vector class is internally synchronized and ArrayList is not.
19. When should the method invokeLater()be used?
This method is used to ensure that Swing components are updated through the event-dispatching thread.
20. How can a subclass call a method or a constructor defined in a superclass?
Use the following syntax: super.myMethod(); To call a constructor of the superclass, just write super(); in the first line of the subclass's constructor.
21. What's the difference between a queue and a stack?
Stacks works by last-in-first-out rule (LIFO), while queues use the FIFO rule.
22. You can create an abstract class that contains only abstract methods. On the other hand, you can create an interface that declares the same methods. So can you use abstract classes instead of interfaces?
Sometimes. But your class may be a descendent of another class and in this case the interface is your only option.
23. What comes to mind when you hear about a young generation in Java?
Garbage collection.
24. What comes to mind when someone mentions a shallow copy in Java?
Object cloning.
25. If you're overriding the method equals() of an object, which other method you might also consider?
hashCode()
26. You are planning to do an indexed search in a list of objects. Which of the two Java collections should you use: ArrayList or LinkedList?
ArrayList
27. How would you make a copy of an entire Java object with its state?
Have this class implement Cloneable interface and call its method clone().
28. How can you minimize the need of garbage collection and make the memory use more effective?
Use object pooling and weak object references.
29. There are two classes: A and B. The class B need to inform a class A when some important event has happened. What Java technique would you use to implement it?
If these classes are threads I'd consider notify() or notifyAll(). For regular classes you can use the Observer interface.
30. What access level do you need to specify in the class declaration to ensure that only classes from the same directory can access it?
You do not need to specify any access level, and Java will use a default package access level.
Simple Java Questions and Answers
The class System has a variable out that represents the standard output, and the variable err that represents the standard error device. By default, they both point at the system console. This how the standard output could be re-directed:
Stream st =

Introduction to Python
It started with 'C', then C++, then java, then perl and many more…
Technology gets better day by day, and it's easy to get started with Python in few minutes.
- Python is a very high level language.
- Programmers, who have used c, c++ or java can smell the familiarity, while appreciating the ease of coding.
- Python can also be used as a object oriented notation.
- Python is a interpreted language. (each line is read @ runtime)
- Python is extensible from other languages and also to other languages.
- The code looks simple and less complex, compared to other base technologies. For instance, there is no open curly brace and close curly brace, defining a block, but a tab would do.
- Python can be used with GUI too.
- Python coders can use data structures effectively for design and implementation, than in any other language.
Downloads Required :
python download (available for windows, mac and unix)
A must see full python tutorial, which is cool!
Why Python?
It is a high level language and you cannot just keep going on with C and C++, for the whole of your life. A more convincing reason - Google search is coded in python, and so are so many other Google products.
Lets get started. (I assume you have downloaded Python and put the IDE shortcut on your desktop)
You must add the python directory to your class path. In windows, you right click My computer -> Properties -> (Advanced Tab) -> System Variables ->
Add or edit variable "path" to append your python directory path.
Or simply in DOS (requires restart of DOS)
set path=%path%;C:python24
Lets get started with the code..
Resisting the temptation to print a "hello world" , which you can achieve by just saying "hello world" (enclosed in double quotes or in single quotes) and pressing the return key (I told you, its simple), we ll write a function to print the Fibonacci series up to n.
def fib(n):
a, b = 0, 1
while b < n:
a, b = b, a+b
print b,
>>> fib (10)
1 1 2 3 5 8
>>> fib (100)
1 1 2 3 5 8 13 21 34 55 89
>>>
Things to notice:
1. This must go first actually, the code looks simpler and less complex than c or java.
2. The >>> is the prompt, which you can change like in unix or solaris.
3. The def command declared a function, by getting its signature and there are no irritating return types or even data types for that matter.
4. The tab after the first line specifies that, all code inside it, are enclosed in a block. The same holds good, when we implement the while loop.
5. After the while command, I did not specify any braces to enclose the condition. Python is more intelligent to know it by itself. The return type need not be a boolean (actually there is no boolean).
6. I did not compile or do any thing to the program and it got executed fine.
7. The print command spits the value of the variable to the screen and a return feed ("\n" in java). The comma that follows it, overrides it to maintain the output in the same line.

Resisting the temptation to print a "hello world" , which you can achieve by just saying "hello world" (enclosed in double quotes or in single quotes) and pressing the return key (I told you, its simple), we ll write a function to print the Fibonacci series up to n.
def fib(n):
a, b = 0, 1
while b < n:
a, b = b, a+b
print b,
>>> fib (10)
1 1 2 3 5 8
>>> fib (100)
1 1 2 3 5 8 13 21 34 55 89
>>>
Things to notice:
1. This must go first actually, the code looks simpler and less complex than c or java.
2. The >>> is the prompt, which you can change like in unix or solaris.
3. The def command declared a function, by getting its signature and there are no irritating return types or even data types for that matter.
4. The tab after the first line specifies that, all code inside it, are enclosed in a block. The same holds good, when we implement the while loop.
5. After the while command, I did not specify any braces to enclose the condition. Python is more intelligent to know it by itself. The return type need not be a boolean (actually there is no boolean).
6. I did not compile or do any thing to the program and it got executed fine.
7. The print command spits the value of the variable to the screen and a return feed ("\n" in java). The comma that follows it, overrides it to maintain the output in the same line.
