Ground Truth: How Engineering Work Actually Works
Researched explainers on what a role really involves, what interviews actually test, and where the picture students carry into an engineering career is wrong. One topic per article.
Why this section exists
A design engineer often thinks that using the CAD or EDA tool is the job. In practice, the job is the reasoning around the tool: manufacturability, cost, timing, power, verification, certification, failure modes. Ground Truth closes that gap, domain by domain, so you know what the work is before you interview for it.
Use it alongside live job, company, and Career Insights pages on HireSetu. When a job posting conflicts with anything here, trust the employer's page for the exact requirements.

What a VLSI Interview Actually Asks (vs What You Studied)
VLSI interviews for freshers and early-career engineers test whether you can reason about timing, power, verification, and debug, not whether you memorised setup/hold…

A fresher can learn Verilog end to end and still have only a partial picture of what chip design involves. Once you stop treating RTL as the destination, the rest of the…
