Everything about metastability, fsm. FIFO buffer in CDC. Setup time, hold time equations. Questions on counters and how to make synchronous and asynchronous counters using JKFF. On site is 8 rounds 45 min each. It was tiring but everyone is welcoming and very knowledgeable. Beware of an Indian Guy. He was very rude.He asked me to present code for my verilog projects instead of questions. He asked me several questions one after another with a time lag of like 4 seconds and would not let me answer them. He then left making disappointing comments. It was my last round of interview everyone apart from him were great.
