Qualcomm High-Speed DDR PHY Designer interview questions

First I had phone interview which was primarily about what I know, one projects which I feel is challenging. It went for about 1 hour. After phone interview I had an on site interview after one month. There were 5 technical round each 45 mins, and one HR round. Technical rounds were mostly about timing, delay, setup & hold time. Since there were dealing with DDR memory controller interface with DDR memory, so they were mostly focusing on PVT variations and impact on timing.
