Hey There
I'm Gautam, Physical Design Engineer with 10+ years of experience.
Why this blog?
This blog covers real Physical Design interview questions across every stage of the flow — Pre-PnR, Floorplan, Power Planning, Placement, CTS, Routing, STA, ECO, Signal Integrity, and Physical Verification. Every answer is written from practical experience, not just theory.
Whether you're a fresher preparing for your first interview or an experienced engineer brushing up before switching roles, this is the resource I wish I had when I was preparing.
That said, this is not to mug up question answeres but for freshers to learn, understand and it's quick revision for experienced people.
