I was referred by the employee in the apple. And it took a long time(one or two months) to get a phone interview. The questions are mainly basic software questions,basic verilog and your own projects. Questions are simple and open ended so sometimes I don't know what they want me to say. The whole experience is quite nice.

There were 1 screening and 6 panel rounds and it was difficult especially UVM part also they AMBA protocols basic design questions like fsm fifo and all and more focus on constraints
