Insider Tips

1.Interface protocols are critical — know PCIe, USB, DDR, LPDDR, I2C, SPI in depth.
2.DSP fundamentals matter for modem/RF roles — FIR filters, FFT, fixed-point arithmetic.
3.Expect questions on memory architecture — caches, TLBs, virtual vs physical addressing.
4.Verification is highly valued — SystemVerilog assertions and UVM coverage-driven verification.
5.Power consumption is top of mind — leakage, dynamic power, power gating techniques.
