Fundamentals · Interview Questions
Interview process
Fundamentals loops are common in campus and new-grad hiring. A resume/coursework screen is followed by two technical rounds on devices, logic, timing, and power, then a project and behavioral close. Devices/logic and timing/coding carry the most weight.
The rounds, in order
4 rounds- 1
Recruiter / campus screen
20–30 min · recruiter / campusBackground, coursework, and interest
What they ask- Coursework and projects (~70–80%)
- Which domain you want and why
- Aptitude, logistics, and availability
- A quick fundamentals warm-up
- 2
Devices & logic round
45–60 min · video + whiteboard≈35% weightCore semiconductor and digital logic
What they ask- MOSFET operation and regions
- CMOS gate design (pull-up/pull-down)
- Combinational and sequential logic
- Karnaugh maps and number systems
- 3
Timing, power & coding round
45–60 min · onsite panel≈35% weightTiming, power, and a small coding task
What they ask- Setup/hold and metastability
- Dynamic versus static power
- 2's complement and number systems
- A small Verilog or C snippet or puzzle
- 4
Project & behavioral round
30–45 min · hiring manager≈30% weightOwnership and motivation
What they ask- A technical deep-dive on a project you owned
- Why hardware, and why this team
- Aptitude and puzzle reasoning
- Thoughtful questions for the team
How to prepare
- Devices: master MOSFET regions and how a CMOS gate pulls up and down.
- Logic: design and analyze small combinational and sequential circuits.
- Timing & power: know setup/hold, metastability, and dynamic versus static power.
- Project: prepare a clear, technical deep-dive on one project you truly owned — your role first.
