very easy and was focused on basics, there were 2 rounds of interview first was focused on semiconductor basics and circuit analysis, second round was mainly focus on backend ASIC design

I had two technical rounds with duration of 1 hour, they mostly focused on basics like semiconductor device physics and CMOS and analog and questions related to my projects in the second interview they asked about schematic and layout design then gave me few problems to solve mostly related to finding the resistance and current in a circuit
