Intel Verification Engineer Interview Guide

This is the initial screening round conducted over the phone. It primarily focuses on your technical knowledge related to verification engineering where the interviewer touches upon topics like verification methodologies, your experience with SystemVerilog, and your understanding of testing and verification concepts.

If you pass the telephonic round, you'll be invited for onsite interviews. These interviews are more in-depth and cover a range of topics. Here's a breakdown of what to expect in each round:

• Testing Verification: This round will assess your expertise in testing and verification processes. Expect questions related to testbench development, coverage analysis, and debugging techniques.
  
• Universal Verification Methodology (UVM): You'll likely be asked about your knowledge of UVM, its components, and how you've used it in your previous roles or projects.
  
• SystemVerilog Constraints and Assertions: Be prepared to demonstrate your understanding of SystemVerilog constraints and assertions. You may be given scenarios to write constraints or assertions.
  
• C Programming and Data Structures: Here, the focus will be on your knowledge of C programming and data structures. You might be asked coding questions or practical problems related to data structures like "how to swap 3 numbers?" or "how to find 3 greatest numbers in an array?" There are typically two questions asked in this round, the first is an algorithmic pseudo-code or digital systems questions. The second is a "thought question"; for instance, they'll give you a code in assembly with a problem in the code and ask you to identify it. For further practice in coding and technical skills, you might find resources on Amazon Android Engineer useful. You might also explore the Google iOS Engineer materials, which provide additional insights into coding and problem-solving.
  
• Logical Puzzles: This round involves solving logical puzzles to assess your problem-solving and critical-thinking skills. To enhance your problem-solving abilities, consider exploring Doordash iOS Engineer interview materials, which often include similar logical and problem-solving questions.

You can practise these interviews through an online platform like Prepfully that offers mock interview resources. It can be extremely helpful to simulate interview-like conditions to get through practice and answer questions confidently and naturally. You can book a 1:1 session directly with a Verification Engineer on Prepfully here.

• How do you ensure no data loss happens in HW to SW communication
• What are the various stages in PCIe linkup?
• Design muxes and write code for Fibonacci series
• What are different types of FSM?
• Can you explain the key components of the Universal Verification Methodology (UVM) and how they facilitate verification?
• What  is the role of a UVM agent, and how does it contribute to the verification environment?
• Could you describe a complex verification project you've worked on recently? What were the main challenges you faced, and how did you overcome them?
• How do you approach test planning and testbench architecture when starting a new project?
• Explain the differences between `always` and `initial` blocks in SystemVerilog.
• What is the significance of the `@(posedge clk)` and `@(negedge clk)` constructs in RTL design and verification?
• When verifying a FIFO design, what are the key conditions you need to check for, specifically related to the FIFO being full or empty?
• Explain the concept of parallelism in SystemVerilog using `fork` and `join_any` or `join_none`. How can these constructs be used effectively in verification environments?
• What is the difference between Static Verification and Dynamic Verification?
• What is the difference between Black-Box
• Compare and contrast the key differences between the Advanced eXtensible Interface (AXI) and the Advanced High-performance Bus (AHB) protocols. When would you choose one over the other for a particular project?
• Given the following assembly commands:
  a. MOV Ri <-- Rj/immediate (put register j or immediate value into reg i)
  b. INC Ri (++)
  c. DEC Ri (--)
  d. JNZ Ri (jump not zero)
  A. Code an assembly program that calculates x*y, where x and y are unsigned integers.
