It was good. Round 1 was a test containing 3 sections-aptitude, c and electronics (digital/communication). I took the digital one. Then there were two technical rounds and a hr. Basic questions asked were related to divide by 2 ckt, 4 bit comparator, in assembly language how to check whether a number is even or odd(check last bit), Fourier transform, setup and hold time and its violation (metastable), d flip flop explaination, noise margin, multiplexers. Make sure u know vlsi, verilog(some were asked a lot) like synchronous reset vs asynchronous, basic coding in verilog,etc, microprocessor/microcontroller, signals and systems, logic design. This was my first interview and it went well but wasn't selected bcoz only a few were selected. All the best
