Round 1 - Technical 

(6 Questions)

  • Q1. Merge intervals ( Leetcode)
  • Q2. Buy and sell stocks II (Leetcode)
  • Q3. Runtime polymorphism and how it works vptr and vtable
  • Ans. 

    Runtime polymorphism in C++ is achieved through virtual functions, vptr (virtual pointer), and vtable (virtual table).

    • Runtime polymorphism allows objects of different classes to be treated as objects of a common superclass.

    • Virtual functions are declared in a base class and overridden in derived classes to achieve polymorphism.

    • vptr is a pointer that points to the vtable of an object, allowing dynamic binding of virtual ...

  • Q4. Which version of c++ you use
  • Ans. 

    I primarily use C++17, but I am familiar with earlier versions as well.

    • I am comfortable working with features introduced in C++17 such as structured bindings and constexpr if

    • I have experience with earlier versions like C++11 and C++14

    • I stay updated with the latest features and improvements in C++ standards

  • Ans. 

    Yes, I have used Windows API's extensively in my previous projects.

    • I have used Windows API's for tasks such as creating windows, handling messages, and interacting with system resources.

    • Examples include using functions like CreateWindow, SendMessage, and ReadFile.

    • I have also worked with specific Windows API's like Winsock for networking and WinINet for internet-related tasks.

  • Q2. What is dynamic_cast where it can fail and what will happen in that case
  • Ans. 

    dynamic_cast is a C++ operator used for safe downcasting of pointers and references in polymorphic classes.

    • dynamic_cast is used to safely downcast a pointer or reference from a base class to a derived class.

    • It can fail if the object being casted is not of the target type, in which case it returns a null pointer for pointers or throws a std::bad_cast exception for references.

    • Dynamic_cast can only be used with pointers o...

  • Q2. What is union in c++
  • Ans. 

    Union in C++ is a data structure that allows storing different data types in the same memory location.

    • Unions are similar to structures but all members share the same memory location.

    • Only one member of a union can be accessed at a time.

    • Unions are useful when you need to store different data types in the same memory space.

    • Example: union MyUnion { int i; float f; };

    • Example: MyUnion u; u.i = 10; // Accessing integer member

  • Answered by AI
  • Q3. What is weak pointer
  • Ans. 

    Weak pointer is a type of smart pointer in C++ that does not control the lifetime of the object it points to.

    • Weak pointers are used to break circular references in shared pointers.

    • They do not increase the reference count of the object.

    • They are used in scenarios where the object may be deleted while there are still weak pointers pointing to it.

  • Q4. What are processes and threads memory is allocated to what process or threads? what is mutex and semaphore how many threads/process can you launch at a time what is meaning of core in 4-core system what is...
  • Ans. 

    Processes and threads are units of execution in a computer system. Memory is allocated to processes. Mutex and semaphore are synchronization mechanisms. Core refers to a processing unit in a multi-core system. Context switching is the process of switching between different processes or threads.

    • Processes are independent units of execution with their own memory space and resources.

    • Threads are lightweight units of executi...

Round 1 - Aptitude Test 

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.

Round 2 - Technical 

(5 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

  • Answered by AI
  • 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

  • Answered by AI
  • 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
  • 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...
