60 mins test which comprises of 2 sections, Technical and aptitude. Both sections have a time limit of 30 mins. The technical questions were easy to medium and i could finish it in time but i needed more time for finishing the aptitude, a total 40 questions.

Q1. Tell me about yourself
Ans. 
I am a recent graduate with a degree in Computer Science and a passion for coding and problem-solving.
• Recent graduate with a degree in Computer Science

• Passionate about coding and problem-solving

• Experience with programming languages like Java, Python, and C++

• Completed internships at tech companies such as Google and Microsoft

Q2. Find the voltage through the resistor
Ans. 
To find the voltage through a resistor, use Ohm's Law: V = I * R
• Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor

• If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V

• Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts

Q3. The interviewer just kept on adding an extra resistor in parallel and in series to the resistor and asked me to find the voltage
Add your answer
Q4. He then asked a question on transient analysis ie 2 capacitors connected in series with a switch which closes at t>0 with the voltage across the 2 capacitors being 3 v and asked to find the total voltge

Q5. Explain the working of a capacitor and resistor and relation between resistance and length , area
Ans. 
Capacitors store electrical energy while resistors limit the flow of current. Resistance is directly proportional to length and inversely proportional to area.
• Capacitors store electrical energy by creating an electric field between two conductive plates separated by an insulating material

• Resistors limit the flow of current in a circuit by dissipating energy in the form of heat

• The resistance of a resistor is directly pr...read more

The interview included a basic coding exercise, followed by a CV screening and questions related to Object-Oriented Programming, such as how virtual functions are implemented by the compiler and how polymorphism operates.

Q1. Toggle the bits of given input
Ans. 
Toggle the bits of given input
• Create a mask with all bits set to 1

• XOR the input with the mask to toggle the bits

• Repeat the process for each bit position

Q1. Print the star pattern
Ans. 
Print a star pattern using loops
• Use nested loops to print the desired pattern

• Increment the number of stars in each row to create the pattern

• Example: for a pattern with 5 rows - * , ** , *** , **** , *****

Aptitude questions and 2 coding questions

Q1. What is difference between list and tuple
Ans. 
List is mutable, tuple is immutable in Python.
• List is defined using square brackets [], tuple using parentheses ().

• Elements in list can be changed, added, or removed. Tuple elements are fixed.

• List is used for homogeneous data, tuple for heterogeneous data.

• Example: list_example = [1, 2, 3], tuple_example = (1, 'a', True)

Q2. What is decorator
Ans. 
A decorator is a design pattern in object-oriented programming that allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects.
• Decorators are used to modify the behavior of functions or methods.

• They are commonly used in Python to add functionality to existing functions or classes.

• Decorators are implemented using the @ symbol followed by the decor...read more

Q3. What is get method
Ans. 
The get method is a function used to retrieve the value of a specified property from an object.
• Used in JavaScript to access the value of a property in an object

• Syntax: objectName.propertyName

• Example: var person = {name: 'John', age: 30}; console.log(person.name); // Output: John
