Interviewing FPGA Engineer
An FPGA Engineer focuses on designing, developing, and verifying hardware products, particularly Field Programmable Gate Arrays (FPGA). They take part in the complete development cycle, from concept to product release stage, and collaborate with multidisciplinary teams to deliver quality-driven results.

Essential Skills for FPGA Engineer

  • Strong knowledge of digital design principles and VHDL/Verilog coding
  • Experience in FPGA development tools (e.g., Xilinx, Intel/Altera)
  • Understanding of synthesis, place and route, and timing analysis
  • Basic knowledge of PCB design and testing
  • Proficiency in communication protocols (SPI, UART, I2C, DDR, Ethernet, etc.)
  • Good problem-solving, analytical, and debugging skills
  • Ability to work collaboratively in a multidisciplinary team environment

Interview Plan for FPGA Engineer:

Round 1: Technical Screening (Duration: 30 minutes)

Objective: Assess the candidate’s basic knowledge of FPGA development and digital design principles.
  • Discuss candidate’s experience with VHDL and Verilog
  • Ask questions about commonly used FPGA tools (e.g., Xilinx, Intel/Altera)
  • Test understanding of synthesis, place and route, and timing analysis concepts
  • Expect candidate to explain previous FPGA projects and their responsibilities

Round 2: Hands-on Technical Assessment (Duration: 60 minutes)

Objective: Evaluate candidate’s practical FPGA development skills and proficiency in relevant software tools.
  • Assign a task for the candidate to implement a simple digital logic circuit using VHDL or Verilog
  • Assess their ability to utilize FPGA development tools for synthesis and simulation
  • Check their understanding of communication protocols and hardware interfaces
  • Expect candidate to debug any issues and provide a working design solution

Round 3: In-depth Technical Interview (Duration: 60 minutes)

Objective: Delve into candidate’s advanced knowledge of FPGA development and their problem-solving skills.
  • Ask questions to gauge candidate’s understanding of FPGA optimization techniques
  • Discuss candidate’s experience with PCB design and testing methodologies
  • Pose complex design challenges to test candidate’s analytical and troubleshooting abilities
  • Expect candidate to provide well-thought-out and comprehensive solutions to the design challenges

Important Notes for the Interviewer

  • Keep in mind that candidates may have experience with different FPGA development tools; familiarity with your specific toolset is a plus but not essential
  • Consider how the candidate’s experience and skills align with the specific FPGA development tasks in your organization, and adapt technical questions to match
  • Remember to assess the candidate’s ability to work within a team; FPGA development often involves collaboration with other hardware and software engineers

Conclusion

Our ideal FPGA Engineer candidate demonstrates their proficiency in digital design using VHDL or Verilog, has hands-on experience with FPGA development tools, and possesses a solid understanding of communication protocols and hardware interfaces. Moreover, they should be comfortable working in a team environment and have problem-solving skills to effectively tackle complex design challenges in Hardware Development.
