Package: 9Lakh

Paper Type: CSE B Tech/M Tech


Time: 1 hour only



Hei,

Written Test:


They have 4 sections,
1. Apti and analytical
2. Coding knowledge : just showing the output
3. Computer c++/Os questions..
4. Computer Systems

My suggestion: Do not start from the beginning means section 1. Start from the technical round. Read the questions and no need to waste more time for long programs see others.

Some concepts from :

1. C++ virtual functions

2. Some from on network.. to transfer 1000 meter propagation delay and transmission delay was given. and asked for 1 bit delay equals to what meter?

3. One 1000ms time to short by one PC of 1000 values by quick sort. What time require to solve 100 values in that PC

Ans: 6.67 ms



4. One system have 8 processor and 8bit require to access one block. and 12 bit require for one instruction accessing within of a block. Amount of memory have?

5. Some Programming questions on C and algo. Just not remember those.

6. Like quick sort complexity

7. U have given the code of insertion sort. But one line missing only. Fill this line...
like A[i+1=key;

8. Max heap is given. u have to insert two more keys. then what will be the inorder sequence.

Interview:

Round 1:

4 question:

1. U have given two array A[n] and B[n+1]. A and B have same elements but B have only one elements more than A. Now U have to find out that element in O(n).

I did that

2. U have to check a number is 2^n or not in constant time.

I did that

3. U have to check a binary tree is BST or not?
Write the algorithm for that.

I did that

4. a,b,c,d are the four values. U have to find out the minimum with ternary operator.

I cant do that

Just within 5min they called for the 2nd round interview..



Round 2:

He asked many question:

1. Why u r doing M tech?

2. What are inside the process?

3. What use of stack in process?

4. What is thread? Why used in OS?

5. What difference with thread and process?

6. Why demand paging is required?

7. Write the code for writing the number of lines reading from a text file. And each line u have to print the number of words that have to print also.

8. What interests u to come in NetApps?



Round 3:HR round

1. Tell me about urself?

2. Scholling btech and mtech details?

3. Why u did BE in IT? Not in CSE?

4. What subjects u prefered?

5. What post u like? Development or Quality testing?

6. What u expects NetApps?

7. Will you have questions on NetApas?
