KPIT Technologies Interview Questions, Process, and Tips

Q1. If i delete an instance on the console and then i deploy the same instance terraform template how will terraform behave?
Ans. 
Terraform will recreate the instance as per the template
• Terraform will detect that the instance is missing and recreate it based on the template

• The new instance will have the same configuration as defined in the template

• Any changes made to the instance outside of Terraform will be lost

Q3. What will be the IP range if i need 500 IPs?
Ans. 
The IP range for 500 IPs would typically be a /23 subnet.
• For 500 IPs, you would need at least a /23 subnet.

• A /23 subnet provides 512 IP addresses (2^9 = 512), with 510 usable IPs after subtracting network and broadcast addresses.

• The IP range for a /23 subnet would be from x.x.x.0 to x.x.x.255.

Q5. What are the health checks after creating instances - 2/2? What do they mean?
Ans. 
Health checks after creating instances ensure the instances are functioning properly.
• Instance status checks ensure the instance is reachable and responding to traffic.

• System status checks ensure the underlying hardware is functioning properly.

• Example: If an instance fails the system status check, it may indicate a problem with the underlying host hardware.

Q1. What is the difference between a microcontroller and a microprocessor
Ans. 
Microcontrollers are integrated circuits designed for specific tasks with built-in memory and peripherals, while microprocessors are general-purpose CPUs without built-in memory or peripherals.
• Microcontrollers are typically used in embedded systems for specific tasks, such as controlling a microwave oven or a washing machine.

• Microprocessors are used in general-purpose computing devices like laptops and smartphones.

Q2. What is pwm
Ans. 
PWM stands for Pulse Width Modulation, a technique used to encode information in the form of a varying signal pulse width.
• PWM is commonly used in controlling the speed of motors by varying the duty cycle of the signal.

• It is also used in LED dimming to control the brightness of the LED.

• PWM signals have a fixed frequency but varying duty cycle.

• The duty cycle represents the percentage of time the signal is high compared t

Q1. What is difference between rank and dense rank?
Ans. 
Rank assigns unique ranks to each distinct value, while dense rank does not leave gaps between ranks.
• Rank assigns consecutive integers to each distinct value based on their order.

• Dense rank also assigns consecutive integers, but does not leave gaps between ranks.

• For example, if we have values 10, 20, 20, 30, then rank would be 1, 2, 2, 4 and dense rank would be 1, 2, 2, 3.

Q2. What is RLS in Power Bi?
Ans. 
RLS in Power Bi stands for Row-Level Security, which allows users to restrict access to data based on their role or profile.
• RLS in Power Bi is used to control access to data at the row level

• It allows users to define rules to restrict data based on their role or profile

• RLS can be implemented using DAX expressions to filter data dynamically

• For example, a sales manager can only see data related to their region using RLS

Thirty-nine questions, including two coding challenges and three to four sets of games.

Q1. What is dynamic dispatch?
Ans. 
Dynamic dispatch is a mechanism where the method to be executed is determined at runtime based on the actual type of the object.
• In dynamic dispatch, the method call is resolved at runtime rather than compile time.

• It allows for polymorphism, where a subclass can override a method from its superclass.

• Examples include method overriding in object-oriented programming languages like Java and C++.

Q3. What are environment variables in linux?
Ans. 
Environment variables in Linux are dynamic values that affect the processes running on the system.
• Environment variables are key-value pairs that are used by the system and applications to determine behavior.

• They can be set, modified, or unset using commands like 'export', 'set', and 'unset'.

• Common environment variables include PATH (for executable locations), HOME (for user's home directory), and LANG (for language set
