  • Q2. C basic questions
Round 2 - Technical 

(2 Questions)

  • Q1. Nonblock vs blocking difference with an example
  • Ans. 

    Nonblocking operations allow the program to continue executing other tasks while waiting for a response, while blocking operations halt the program until a response is received.

    • Nonblocking operations allow for asynchronous communication, while blocking operations are synchronous.

    • Nonblocking operations are typically used in event-driven programming, while blocking operations are common in traditional procedural programm...

  • Q2. DFF Vs latch difference
  • Ans. 

    DFF stores data based on clock signal, while latch stores data based on enable signal.

    • DFF stands for Data Flip-Flop, while latch is a level-sensitive storage element.

    • DFF stores data on the rising or falling edge of the clock signal, while latch stores data when the enable signal is high.

    • DFF has two stable states (0 or 1), while latch has only one stable state.

    • Example: D flip-flop, T flip-flop are examples of DFF, while

I applied via Recruitment Consulltant and was interviewed before Aug 2021. There was 1 interview round.

Round 1 - Technical 

(2 Questions)

  • Q1. What is aspect ratio?
  • Ans. 

    Aspect ratio is the ratio of an object's width to its height.

    • Aspect ratio is commonly used in design and engineering to maintain proportionality.

    • It is often expressed as a ratio, such as 16:9 for a widescreen TV.

    • Aspect ratio can affect the visual perception and usability of a product.

    • It is important to consider aspect ratio when designing graphics or layouts for different devices or mediums.

  • Answered by AI
  • Q2. How do you decide stackup?
  • Ans. 

    Stackup is decided based on the number of layers, signal integrity requirements, and manufacturing constraints.

    • Consider the number of layers required for the design

    • Evaluate signal integrity requirements and impedance control

    • Take into account manufacturing constraints such as minimum trace width and spacing

    • Balance cost and performance

    • Use simulation tools to optimize the stackup

    • Consult with PCB fabricators for their reco
