Behavioral Interview Questions

Behavioral Interview Questions  

Please refer below are very  frequent questions which I have been gathered from my interviews across all of companies/client that I have worked so far, and hope sure it will be helpful for your interviews - Thank you.

Behavioral Interview Questions are those questions which identify the attitude of a candidate towards a company and work performance and are especially helpful in recruiting. We are human and being this great creature we have some limitation. I mean to say that if we don’t know our target, then we cannot make a plan. Also, if we don’t have questions we cannot find answers. Recruiting has become a great science so here are some questions that are widely used around the world to measure the behaviors of people in an interview.

1.     What was the last project you headed up, and what was its outcome?

2.     Give me an example of a time that you felt you went above and beyond the call of duty at work.

3.     Can you describe a time when your work was criticized?

4.     Have you ever been on a team where someone was not pulling their own weight? How did you handle it?

5.     Tell me about a time when you had to give someone difficult feedback. How did you handle it?

6.     What is your greatest failure, and what did you learn from it?

7.     What irritates you about other people, and how do you deal with it?

8.     If I were your supervisor and asked you to do something that you disagreed with, what would you do?

9.     What was the most difficult period in your life, and how did you deal with it?

10.  Give me an example of a time you did something wrong. How did you handle it?

11.  What irritates you about other people, and how do you deal with it?

12.  Tell me about a time where you had to deal with conflict on the job.

13.  If you were at a business lunch and you ordered a rare steak and they brought it to you well done, what would you do?

14.  If you found out your company was doing something against the law, like fraud, what would you do?

15.  What assignment was too difficult for you, and how did you resolve the issue?

16.  What’s the most difficult decision you’ve made in the last two years and how did you come to that decision?

17.  Describe how you would handle a situation if you were required to finish multiple tasks by the end of the day, and there was no conceivable way that you could finish them.

At the end of this post I would like to ask you to read a lot because good readers are good leaders…

Subconscious mind in my view

The subconscious mind can guide you to achieving prosperity, power and peace based on how you allow it to be programmed.   The subconscious mind is your intuition.  To strengthen the connection between your conscious mind and your subconscious mind is to gain access to a map and compass to achieving any ambition.  To gain access to the subconscious mind is to gain the ability to see and create the future, the ability to shift the present, and the ability to harness the lessons of the past.  To master the subconscious, is to master yourself.  To master the subconscious, is to achieve an unfathomable power of creation.


Whatever the mind of a man can conceive and feel as real, the subconscious can and must objectify. - Neville Goddard

Finding Memory Leaks using JProbe

How to prevent Memory Leaks :

We can prevent memory leaks by watching for some common problems. Collection classes, such as hash tables and vectors, are common places to find the cause of a memory leak. This is particularly true if the class has been declared static and exists for the life of the application.

JProbe Memory

The JProbe Memory analysis tool enables you to:

·         Identify and resolve memory allocation issues. (For eg. when in your code if you are doing explicity memory allocation, then the tool would ensure that you are freeing up the memory also.)

·         Identify the underlying root cause of memory leaks that can lead to instability and out-of-memory system crashes.

·         Identify the underlying root cause of excessive garbage collection activity which can slow down the system performance. (For example when memory is allocated and is not freed up, the garbage collection would need to be run often)

JProbe Memory Debugger helps you improve memory usage in your Java application by identifying loitering objects and excessively allocated objects.

A loitering object is an object that is determined to be reachable by the garbage collector, but is no longer in use by your application. So if your program will never use an object again, but you fail to remove the reference to the object, the object will remain, or loiter, in memory indefinitely. This problem is commonly referred to as ?unintentional object retention? or loitering objects. Additionally, loitering objects can compound memory usage problems if that object is acting as an anchor to other objects that would otherwise be marked as unreachable by the garbage collector and therefore removed.

If your program creates an excessive number of objects, the Java heap will become larger, and garbage collection will take longer because there are more objects to evaluate. A simple example would be a method that allocates a new temporary object during each iteration of a loop, even though the object is never reused and is no longer required when the loop terminates.

Unix Exercises

                                                Unix Exercise

1. Create a directory with your name under the default home directory for the user “traineee”.
2. Create a file “samplefile” in your home directory.
3. Give the file above appropriate permissions if necessary. What do you think appropriate permissions should be?
4. Turn the sticky bit on for the directory you have created
5. Write a script which prompts for your name and then prints on stdout Hello “yourname” Today is “today;s date and time”
6. Write a script to print the names of all the files in the current directory using for loop
7. Create a file “-myfile” in your directory.
8. Remove the above file
9. Write 100 lines in a file each containing text “Unix is a wonderful world”.        Hint : Use a loop construct
10. Write a shell script which will take 3 command line arguments and perform arithmetic The 3 args in the order are number number operation

number is a normal integer

operation could be sum, difference or product

Hint (Use functions, $#, case, expr etc)

Use tail to show the contents of dynamically growing file.

Hint echo a message in a file using infinite loop . also place a delay so that the file doesn’t grow very rapidly. Open one more session to run tail.   

Given a file named “/data/training/sam/inputfile”, do the following in separate scripts

a.       Print the count of all the blank lines

b.      Print all the lines having the string “new” in them

c.       Print all the lines having the last field greater than 20000

Hint:          Use awk

Copy all the files and subdirectories under /data/training/sam to /data/training/yourgroupdirectory/.

Hint: Use tar cvf to create the tar first from /data/training/sam and then untar the created tar under /data/training/yourgroupdirectory using tar xvf

           

Use the find command in /data/training/sam (separate scripts)

d.      To print all the files having 0 bytes

e.       To print all the directories

f.       To print all the files having only read permissions for u,g and o.

Use grep or related filter to print lines containing either Arizona or California (case insensitive search) in the file /data/training/sam/inputfile.

Read the file /data/training/sam/inputfile line by line and print each line followed by a line saying “This was line n “  n=1,2,3..

In the file ( containing 50 lines “Unix is a wonder….”, replace all the occurrences of wonderful with gruesome )

Also add “This” at the start of each and every line

Write a shell script which will write a warning to a file if any of the local filesystems exceeds a certain limit (70 %). The script would write the date and time as well as the name of the filesystem along with the current capacity in percenatge.

These are the contents of  /data/training/sam/inputfile

Unix - SED - Stream Editor

SED  -   Stream Editor

•Reads one line at a time from input files

•Applies the commands from a list of commands one at a    time, in order, to each line

•writes to standard output

Usage

sed ‘list of ed commands’ filenames...

Example

sed ‘s/UNIX/UNIX(TM)/g’ filenames

replaces UNIX by UNIX(TM) in all the file occurences and writes the result to standard output

COMMANDS

a\  text  Appends text on the output before reading the   next input line

b label  Branch to the : command bearing the label

c\ text  change lines to the following text

d  delete line; read next input line

p   print

r  read

w  write

q  quit

AWK - Unix

What is AWK ?

Scans a set of input lines, searching for lines that match any set of patterns and take a specified action for each pattern on each line that matches the pattern

 Usage

awk ‘pattern-action statements’ optional list of input files

e.g. awk ‘{print $1, $2}’ file1 file2

OR

awk -f programfile optional list of input files

where programfile is the file where the pattern-action statements are stored

 Fields

Record is the sequence of characters separated by a newline character

Fields in a record are separated by sequence of blanks or tabs

$0 refers to the entire record

$1 refers to the first field

$2 refers to the second field

Printing

{ print }

prints all the records

{print $1 $3}

prints the first and third fields of each of the input line

BuiltIn Variables

ARGC  number of command line arguments

ARGV  array of command line arguments

FILENAME  name of current input file

FNR  record number in current file

NR   number of current record

NF  number of fields in the record

OFS  Output field separator

ORS  Output record separator

 Examples
Print last field of each input line

{ print $NF }

Print total number of input lines

END {print NR}

Print input lines with more than 4 fields

NF > 4

Print the total no of lines that match string “abc”

/abc/  {nlines++} END {print nlines}
