1)In a company there are 2/6 java programmer,1/2 programmers knows c++ and 1/5 programmer doesn\'t know anything.Then find the
fraction of programmers who knows java and c++ both. There were 2 question of same pattern with different data.
2)There is a cake which is divided into two sub-cake.One part of sub-cake is further divided into 5 sub parts each weighing 12gm. What was the initial
weight of the cake before division?
3) Two printers each produced 48000 prints per day. One computer printed at the rate of 9600 an hour and the other at the rate of 7800 an hour.
When the first computer finished its run, how many bills did the other computer still have to print?
4)In a company there are 60% are men and 40% are women. in that 80% of men and 60% of women are in pension skim. therefore how much % of employees are in pension skim.?

maintenance last month?
8)For a poetry concert of 30min a poet takes 1 hour for writing the poem and another 6 hour of rehearsal. How much time the poet will take for 90 hour
concert?
9)The cost price of a scooter was Rs.12750.It was sold to Ramesh at 5% profit.Again Ramesh sold it to Kamal at 8% profit. Now find the selling price if
kamal wants to sell the scooter again with 5% profit to Dinesh?
10)One question was based on library issuing a book twice per week to one student and the book can be re-issued 3 times in 8 weeks .....Dont remember the question exactly.

2nd Round- Technical Written Test
Total 40 questions in 40 min. 20 question from c,c++,java debugging. Other 20 were based on OS, Data Structure, Algorithm Time complexity, Database and Unix.
Few of them were: One question from each topic
Max Heap,Avg Time complexity of linear search(Ans=o(n+1)/2), postfix expression evaluation(m=1*2+j/2+(j/k)*2+1 where i=3,j=6,k=5,
infix to postfix(A(B+D)/E),Deadlock condition, Database query, Page fault with frame size 3 using Optimal page replacement Algo, Shortest Job first, TCP/IP numerical problem, complete graph(Ans was n(n+1)/2),one question from Session layer in OSI protocol.
Round 3: Technical Interview
1.What is cloud Computing. Explain Aas,PaaS,SaaS
2.Difference between Cloud computing and Virtualization.
3.State and prove the time complexity of linear search is O(n+1)/2
4.Can a deadlock occur with a single resource?
5.write code for quick sort and derive its time complexity(worst,avg,best).
6.How can you switch from user mode to kernel mode?
7.What is difference between "new operator" and "operator new"?
........
I almost answered all questions.
Round 4: Technical Interview
1. Do u know Unix?
Yes sir
2. Write the output for ls-l

$ ps
6.Write the output for p-al.
I wrote it but with few mistakes
7.Which has heighest prority ps-l,troff or sh??
Sir sh
8.what\'s the difference between ping and traceroute?
Bla bal bal...
9. Expalin OSI layers.....few more questions on TCP and UPD were asked
No 3rd round Tech interview and HR for me as they were satisfied with my
Performance but for some students HR +3rd Tech round was conducted.
Results were announced 2 students got selected and with God grace I was one among them.
Prepare well and give your best!!!
Hope my experience helps you and my juniors at SASTRA University.
All the very best.
I\'m very glad to share my experience with you all once again.
