HR

1.introduce urself
2.explain ur project
3.any problem u faced in life.explain it in detail.
I want to tell a small point here.

some are...

I) 1.how to find the jth node from last node in a single linked list in one search,the condition is i have not given the length of the linked list?

2.differentiate the call by value and call by reference?

3.defferentiate the static and volatile variables? 4.define macro?

5.write the gcd programm?

6.i was given a program to find the output? i=printf("hellow"); printf("%d",i);

7.define register variable? advantage?

8.#define a(a,b) a*b; printf("%d",a(2+3,2+3));

9.define avl tree,2-3 tree,btree,bst?what are balanced tree?

10.diffrence between tree to bt?

II) 1.abot urself.

2.tell me abt ur final sem project.

3.ur interesting subjedct(i told electronics related topics)

4.why u wnt to join wipro

5.if u got any offer for higher studies do u stick wt wipro... some ......(these are some asked to me in the interview)

dont panic its very easy dont get tense they are friendly enough to answer the questions

In the interview they will test ur basics, abt ur final yr project, and basics of c. and whatever u wrote in ur resume.

III) They ask you questions regrading 1) final year project(this is very imp. section..explain your project as nicely as possible)

2) why u chose that project?

3) C/C++ skills(this may include framing a program of their wish or if you are luckythen simple questions based on the programming language)

4) your favourite subject(Be carefull and prepare that subject throughly)

IV)
In tech interview they asked me about

1) data structures:
sorts(their complexities)
linked list,
uses of trees
about malloc
quick sort's logic

2) in C
simple program outputs.
pointers.

3)in n/ws
About protocols and to which layer they belong
About FTP,TFTP,TCP,UDP,IP
about internet addresses(class A,B and so on).

4) About my project

5)in OS
Virtual memory,Paging ,Segmentation etc.

My experience::
Technical:


1)i was asked to explain about my project.
2)then he asked me write a query in oracle --> select the duplicate names in a table(ename,empid)
3)abt SQL,
4)stmts in oracle(DDL,DML,DCL,TCL) and explain,
5)some in c++, some in C,
6)diff. between c and C++,
7)what is OOP, features of OOps,
8)what is a structure,
9)can 2 diff, machines in 2 diff. companies(eg. WIPRO and TCS) have same IP address (Ans: yes,if they have a subnet mask).
10)what a grid in VB how does it differ from other tools?
11)what is a t-list in VB(i didn't know)
12)what is ODBC,ADO,DAO.
13)examples of RDBMS
14)what are diff kinds of DBMS?
15)what is LAN,WAN?
16)what does W in WLAN stand for?
17)What is Linux,Unix.
18)In what way does unix differ from Windows
19)where do we use Unix.


HR was as usual...formal HR Qs.

My friend was asked Qs in Java and C++. thats it....

i think have done my work, now its up to u to prepare well and get thro'. One thing i found was they are also checking ur confidence level.. they want people with confidence...not alone the stuff...
