Top 10 Interview Tips OF Hughes:
================================

Here are the 10 most commonly asked questions in the job 
interview, which will
help you prepare yourself better for the forthcoming campus 
placement and also
give you a competitive edge over others. 

A well thought out answer to these questions, prepared and 
rehearsed in
advance with the logical sequencing of the events will help 
you sail through.

                   1. Tell us about yourself

This is an open canvas for you giving you an opportunity to 
direct and lead
your interview in the direction you want. Good idea will be 
to structure your
answer in the following three broad heads:
Family Background
                       Educational Background (starting 
from schooling to
                       professional qualifications) 
                       Achievements

In all the above subheads speak only that information which 
will give strength
to your candidature. Avoid verbose description of yourself. 

                   2. Why do you want to join us? 

To answer this question, you must have researched the 
company well. Here you
can quote some of your personal beliefs, which are in 
conjunction with the
values of the company or talk about specific products and 
services which could
be your professional interest too.

In the event where your skill set is mapping with the 
requirement of the
company, do not miss the chance to highlight the same. 
Specify the initiatives
taken or work done to attain that skill set. 

3. What would you like to be doing five years from now? 

This question is asked to assess candidates career plan and 
ambition for
growth and to see if the company will be able to provide 
that opportunity over
period of time. Also to assess if your personal goals are 
not totally off
tangent with what companys objectives are. It is also to 
check your stability
with the organization. It is good idea to be very realistic 
in your answer. If
need be take guidance from your seniors who are already in 
the corporate
environment. 

                   4. Do you prefer working with others or 
alone? 

This question is usually asked to determine whether you are 
a team player.
Before answering, however, be sure you know whether the job 
requires you to
work alone. Then answer appropriately. 

                   5. What are your biggest accomplishments

You may like to begin your reply with: "Although I feel my 
biggest
achievements are still ahead of me, I am proud of my 
involvement withI made my
contribution as part of that team and learnt a lot in the 
process".  It will
be a good idea to close your answer with also specifying 
what attributes and
circumstances made you succeed. 

                   6. What are your favorite subjects

 It is a leading question giving direction to the panel 
members for possible
areas where they can probe in further for your knowledge 
base and in depth
understanding. It is advisable to select the topics that 
you are competent in.

                   7. Why should we hire you? 

Keep your answer short and to the point. You should 
highlight areas from your
background that relates to the need of the organization. 
Recap the
organizations description of the job, meeting it point by 
point with your
skills.

                   8. What are your hobbies? 

This question is generally asked to assess whether you 
are "desktop" kind of a
person or an "interaction orientated person". It also 
indicates your
preference for team - oriented activities or projects with 
solo contributions. 
It enables the organization to place you accordingly after 
selection. Be
candid with your answer.

                   9. What is the worst feedback you have 
ever got? 

To answer this question you must admit and share your areas 
of improvement.
Also sharing an action plan for improving oneself will 
indicate your ability
to take criticism well. Your answer should be reflection of 
your
open-mindedness.

                   10. What is the most difficult situation 
you have faced? 

Here you should be ready with the real life story. The 
question looks for
information on two fronts: How do you define difficult? 
and, what was your
handling of the situation? You should be able to clearly 
lay down the road map
for solving the problem, your ability to do task management 
and maintain good
interaction with your team members and other peers. It is 
advisable to close
with highlighting the learning out of the incident.
