Topics asked in Mu Sigma Technical Interview of Coding branch (IT/CSE/ECE):
For CS/IT the main thing that you should be concerned for is your projects i.e. minor & major, industrial training, computer languages etc. Be prepared for everything that you have mentioned in your resume and do not write anything that you don't know just to impress the interviewer.
Few question that have been frequently asked in the technical round of Coding Branch are:
- Explain your projects.
Try to explain your projects in both technical as well as layman process.
2. What are your favorite subjects?
Choose either multiple or a single subject but you have to be confident about the subject and its concepts as the interview can ask question from level basic to advance.
3. What is polymorphism?
Polymorphism is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.
4. What is Encapsulation in JAVA?
Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines.
We can create a fully encapsulated class in Java by making all the data members of the class private. Now, we can use setter and getter methods to set and get the data in it.
The Java Bean class is the example of a fully encapsulated class.
5. What is UNIX?
UNIX is a complete package of the operating system developed mainly for servers, workstations, and mainframes. It is a copyrighted named. It can be used by its copyrighters only. It contains a completely different coding developed by AT&T labs, highly secured, has listed about 85-120 viruses till date.
6. Write a code in your favorable language. For example:
Write a JAVA program to print Fibonacci Series
class programme
{
public static void main(String args[])
{
int i;
int array[]= new int[11];
array[0]= -1;
array[1]=1;
System.out.println("The Fibonacci series is: ");
for(i=2; i<array.length; i++)
{
array[i]= array[i-2] + array[i-1];
System.out.print(array[i]+ " " );
}
}
}
7. What are the major Data Structures used in RDBMS, Network Data Model and Hierarchical Data Model?
RDBMS: Array (i.e., Array of structures)
Network data model: Graph
Hierarchical data model: Trees
8. Give some advantage of DBMS.
Advantages of DBMS are:
a.) Redundancy gets controlled
b.) Enforcing integrity constraints
c.) Unauthorized access is restricted
d.) Providing backup and recovery
9. Which operation in SQL perform pattern-matching?
LIKE operator performs pattern matching.
10. What is OSI model?
Layers of OSI model are:
1. Application layer ( 7th Layer)
2. Presentation layer (6th Layer)
3. Session layer (5th Layer)
4. Transport layer(4th Layer)
5. Network layer(3rd Layer)
6. Data Link layer (2nd Layer)
7.Physical layer(1st Layer)
Topics asked in Mu Sigma Technical Interview of Non-Coding branch (EEE , EIE and EE ):
For non-coding branch the main focus of the interviewer will be on your projects. Try to explain your projects as simple as possible because he/she might not be aware of technical terms of your branch. Other things such as favorite subjects and industrial training are also asked in will cover only basic concepts.
Few question that have been frequently asked in the technical round of Non-Coding Branch are:
1. What is Control System?
In a System the output and inputs are interrelated in such a manner that the output quantity or variable is controlled by input quantity, then such a system is called Control System. The output quantity is called controlled variable or response and the input quantity is called command signal or excitation.
2. What is a feedback in Control System?
The Feedback in Control System in one in which the output is sampled and proportional signal is fed back to the input for automatic correction of the error ( any change in desired output) for futher processing to get back the desired output.
3. What are the different losses that occur in thyristor while operating?
Different losses that occur are
a)Forward conduction losses during conduction of the thyristor
b)Loss due to leakage current during forward and reverse blocking.
c)Power loss at gate or Gate triggering loss.
d)Switching losses at turn-on and turn-off.
4. What Are The Key Components Of Control Loop?
A closed control loop in a very basic manner consists of sensor, transmitter, controller,signal converters and final control elements. Actually in a practical loop there will be many other instruments apart from this to support the working of above mentioned instruments.
5. What Is Difference Between Differential Pressure & Delta Pressure?
Differential pressure means difference between high pressure & low pressure delta pressure means it is the pressure drop.
6. How To Trim The Pressure Transmitter?
a.) Ensure that you have the necessary document on your hand such as PTW.
b.) Connect a HART Communicator, then close the Tx isolation valve and open the VENT isolation to atmosphere
c.) Apply LRV and check w/ HART Comm, if the LRV is out, perform TRIM function using HART 375/475
7. What is Superposition Theorem?
The superposition theorem states that in a linear circuit with several sources, the current and voltage for any element in the circuit is the sum of the currents and voltages produced by each source acting independently.
8. What are Semiconductor?
Semiconductors do not fall into either the conductor or non-conductor categories. Instead they fall in between. A variety of materials fall into this category, and they include silicon, germanium, gallium arsenide, and a variety of other substances.
9. What is Q factor?
For electronic circuits, Q is defined as the ratio of the energy stored in the resonator to the energy supplied by a to it, per cycle, to keep signal amplitude constant, at a frequency where the stored energy is constant with time.
10. Write a program in your favorable language. For example:
Write program in C to print Fibonacci Series:
