JINDAL STEEL PREVIOUS EXAM PAPER 2008

JINDAL PAPER ON 17th FEBRUARY AT KOLKATA

The test of JSPL held on 17th February 2008 was more or less of an easy type for instrumentation stream. Many questions were from power electronics and communications. The ques that I remember were:

Verbal (20 ques):

1. 10 ques based on two RC passages,dealing with computer languages.

2. remaining ques on articles, prepositions and word meanings.

Numerical (20 ques):
1. all ques based on simple but lengthy calculations involving %ages, profit and loss, ratio-proportion,etc.

Attention to detail(15 ques):
1. ques based on pattern recognition, logical reasoning and types like if + is -, - is *, etc.

Technical (60 ques-INSTRUMENTATION):
