SUN MICROSYSTEMS PAPER - DEC 2006
60 questions 60 marks
Everything is multiple choice. BEWARE OF NEGATIVE MARKING .
Section 1 : Operating Systems 20 questions
Section 2 : Technical Programming 25 questions
Section 3 : Aptitude 15 Questions
Section 1 : Operating Systems
Study all the unix commands & some basic networking concepts like DHCP, Dynamic NAT, RARP, ARP, UDP, DNS. Unix : Grep, sed, basic perl program whose o/p is to be predicted. Pipes. You can expect some nasty & tricky questions !. But this section is kool not to worry too much.
Section 2 : Programming part
C programs & Java programs. The programs seems to be easy but bcoz of the Negative marking (0.5) we have to be very clear. No bluffing ok! The programs are easy. Programs were on Fork, PID, Basic C syntax, Basics of Java, Exception handling, Inheritance, Strings, Cast conversion, Object linking etc
Section 3 : Aptitude
Most of the questions can be found from other placement papers like Sonata, TCS, Caritor. Nothing to worry much. But again you have to be very confident about the answers.
The cut-off marks are not told & will be decided by the evaluators at that time. Only 3 out of some 50 candidates got through. The next rounds are technical interview followed by HR interview. This interview call was purely on referral basics. So not much competitors & really a good chance of getting thru !. Do well & good luck !
