I was referred by my friend. After which hiring manager called me for phone interview. It went well. I was then called for on-site interview: - On-site interview went for ~ 5- 6 hrs. - Interviewed by 4-5 individuals. - questions were mostly technical, touching on these areas: - ASIC Implementation flow. - What projects you worked on, describe how you implemented the chip/design. - TCL related questions. (like lappend etc..) - How will you analyze and fix setup time, hold time. - Routing using higher metal layers.
