They question only what they want, ofcourse that's the requirement of the opening. But they select wrong candidates. I never had experience in protocol testing nor SMB/NFS/FC/.... which mentioned exactly same in resume. But they scrutinized in panel round on them even when I claim that I cannot answer them. Interviewer just walked out, no professionalism. What if I have asked him PCIe protocol questions which he never worked. Jerks in Nutanix.
