Re: Steel Authority of India Ltd - SAIL Management Trainee Computer Science Engineeri

As you want I am here providing you sample paper of the Steel Authority of India Ltd - SAIL Management Trainee Computer Science Engineering exam.

Sample paper :

1. Language which support diamond inherritance
a) C++ b) Java c) Both a and b d) None

Some basic sql functions like trunc some questions from Oracle in C.N

All of them basic questions

Diff b/w hub and switch?

What happend to header of packet if routed from bottom to top layer etc.

Section II

Refer any Text book of Quantitative Aptitude

Read Competition Success for G.K and English
Part -1 Technical ( 100 Questions Computer Science)

Q(1) What will be output of the following-
(a) tim (b) keep printing tim (c) black screen (d) none

Q(2) In which Data structure insertion and deletion is not possible in middle but at ends.
(a) Linked list (b)Pointer Array (c) Queue (d) Dqueue.

Q(3) OSI Model consist of how many Layer

(a) 2 (b)4 (c) 7 (d)9

Q(4) Why NAND gate is called universal gate?

Q(5) Which of the following not supported by C++

Some other questions I am not remembering exactly. But approx 8 simple questions were based on OSI model layer and 7 Question based on simple SQL queries and 15 questions based on Java and C++ and 7 question on digital electronics and 15 question on Operating System and 15 on Data structure.

C++, Java, DBMS, SQL, Computer Network, Operating System and Data Structure are the subject from which questions were asked in paper.

Overall Technicl section was easy but need some rivision of technical question.
