The manager asked me about my resume and some projects I've done before. After that, he kept asking me some general digital circuit's problem, like power consumption and the delay.

3 phone interviews. 1st one was about device physic, capacitance in drain source and gate, leakage current in several circuit. 2nd about verilog, some basics. 3rd about SRAM and dynamic circuit, I guess because I had some experience on these, mostly about power issues. Lots of details but nothing out of normal.
