SIEMENS INFORMATION SYSTEMS LTD
WRITTEN TEST:
The written test consists of 50 questions divided into 6 sections to be completed in 40 minutes. The questions are technical based; you can expect to be tested on DBMS, C++, C, Unix, Motif, x-windows, MS-Windows. The test is a multiple based one and is not tough. The questions can be answered easily in 40 minutes provided you have some knowledge about the subjects.
INTERVIEW:
The test is followed by a Technical and a HR interview. The technical interview is highly specialized and covers almost all subjects you have done in your curriculum. However one is required to name his/her favorite subject on which most of the interview is focused. For Computer Engineers C, Operating Systems, DBMS, Microprocessors are mostly focused upon. Electronics Engineers are grilled upon DCLD, Microprocessors and Communications. For details on the frequently asked questions please refer to our interview Section. The HR interview, which follows the technical interview, is very general. In most cases questions regarding the company are asked.

Siemens-2:
All are multiple choice questions.60 questions to be answered in 60 mins.
Distribution of questions:
10 questions from data structures and some general topics.
10 questions from Unix and C.
7Questions from Database.
Remaining from Windows (x windows, MS Windows etc..)
The distribution is not exact. Only approximate.
Totally there are six sections as below:
1. General
2. Unix and c
3. RDBMS
4. C++/object oriented
5. TCP/IP
6.
The questions are as follows:
RDBMS-
1. What is RDBMS?
2. Two tables are given. In 1st table 2 columns are there. One is Employee no, second is salary. In second table 3 columns are there. One is Employee no, second is date, 3rd is salary.
Select employee no from table1, table 2.
How many records it will contain? (This is somewhat difficult).
3. What is transaction?
TCP/IP:
1. X.25 protocol belongs to which layer?
2. Order all the 7 layers in sequence
3. One node has 2 IP address but data goes through only one link. What is the reason?
4. Router, Bridge, Gateway. Which one of these cannot connect two different LANS and is protocol sensitive?
5,Client sends server---request or demand or -----Choices are given.
Another section...
1. main (argc, argv)
{
if (argc<1)
printf ("error");
else
exit (0);
}
If this program is compiled without giving any argument , what it will print?.
2. What are the static variables?
3.What is Dynamic allocation?
4. Dead lock condition...What may be the condition for it?
5. Semaphore variable?
6. Most of the Windows operating systems are....choices are given like
a) multitasking, multi-user, multi processing b) only.......&......
c) only........&......
7. Properties of object oriented (just recall the name of the properties like inheritance)
8. A program of C++, and two questions were based on the o/p of that program.
Sections...
1. 5Q ...x windows
2. 5Q .....MS Windows
3. 7Q.....Databases
4. 20 Q....General
5. 20Q....UNIX/C
6. 5Q ....OOPS
Some questions:

3. Net work layers
4. Ethernet, Token Ring
5. Unix...(Ans: Multitasking, Multi user)
6,Windows...(Ans: pseudo multitasking)
