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 goodmarks ,it will help u in the technical round so try to clear writtentechnical 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 runningon each page.

For mathematical aptitude : just remember the formulas of R.SAGGARWAL and solve or concentrate on Examples. This is more thanenough.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 frombarron's gre 12th edition try to remember the answers of model testpapers,synonys antonyms are very difficult, if u are good in english then only ucan be confident otherwise hit any options as i did.

Technical questions As this was my 3rd attempt for a core company irealized 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 ask1-2 question only in next technical round. Some of them are

Technical written:1. Work done is Zero for which process?2. Which cycle has high efficiency?

Technicalno favourite paper they ask questions from manufacturing science,fluidmechanics etc so remember definitions and procedures of mnufacturingsectionsex. which process is used for making piston,car body,engine cylindercoin etc dont bluff on any question otherwise u will be rejected


11/11

In the PI they ask very simple questionstell me something about yourselffamily background

project if any

hobbies,interest,strength etc

TIPS:answer in simple sentences,politely they may ask in hindi also if u arenot good in english and scored good in written technical

Only u have to be confident,genuine , don't bluff or guess on anyquestion 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
