I applied for this job after I completed my B.Tech graduation. 1st Round: Asked about project. Then asked me about the basics of Physical Design like the VLSI PD flow, setup & hold time problems, how to fix, etc. 2nd Round: Was completely on the Physical Design Flow. What input files are required at what stage of the flow? What are present in .libs, lef files, etc. General ways to fix setup and hold time violations. 3rd Round: This was completely based on my projects that I did in my Internship & in college.
