There're 5 rounds of assessments. You start with a pretty aptitude test which is pretty standard. It's followed by a hack rank test with digital circuit and VHDL questions. Then there'll be an HR interview with a bunch of behavioural questions. Preparing some of those common ones with STAR approach can be helpful. Next one is the technical interview (finally!) run by FPGA developers. Expect some system design questions, (e.g. sorting, table searching matching etc). In the final day, you'll have one final behavioural and technical interview. Expect to be asked about the answers you made from the previous technical interview.
