ESSAR PAPER ON 16th OCTOBER AT BHUBANESWAR
HELLO FRIENDS. This is RAVI GUPTA ORISSA ENGINEERING COLLEGE
, BHUBANESWAR I am providing you selection procedure and
question papers of ESSAR.
Eligiblity for 2009 passing out batch 60% in B.Tech and Date
of Birth after 1-05-1986.
1st Company's PPT.
2nd online writtten test.
3rd technical .
4th PI.
Online written Test - This is the main round u have to clear
it with good marks ,it will help u in the technical round so
try to clear written technical with good marks.
Written paper has 4 sections- mathematical aptitude,
reasoning, english, technical .
All questions are very easy but you have to concentrate on
time running on each page.
For mathematical aptitude : just remember the formulas of
R.S AGGARWAL and solve or concentrate on Examples. This is
more than enough.
If you are good in calculations just concentrate at the time
of test.
English: Passages are very easy and scoring ,Fill in the
blanks all from barron's gre 12th edition try to remember
the answers of model test papers,
synonys antonyms are very difficult, if u are good in
english then only u can be confident otherwise hit any
options as i did.
Technical questions As this was my 3rd attempt for a core
company i realized that all companys are asking mechanical
questions from the book Mechanical Engineering (conventional
and Objective Type)
S.CHAND writter R.S. KHURMI and J.K.GUPTA so try to remember
objective as more as u can, it will help u for all campus
selections.
In essar if u will perform in written technical section then
they will ask 1-2 question only in next technical round.
Some of them are

Technical
no favourite paper they ask questions from manufacturing
science,fluid mechanics etc so remember definitions and
procedures of mnufacturing sections
ex. which process is used for making piston,car body,engine
cylinder coin etc dont bluff on any question otherwise u
will be rejected
In the PI they ask very simple questions
tell me something about yourself
family background
project if any
hobbies,interest,strength etc
TIPS:
answer in simple sentences,politely they may ask in hindi
also if u are not good in english and scored good in written
technical
Only u have to be confident,genuine , don't bluff or guess
on any question simply say i dont know sir they are very
good and genuine people dont wear any tie.
ALL THE BEST HOPE TO SEE U AT ESSAR |
