I honestly think its too much of a drag and insistence on data structures. I worked for more than 10 years in this industry and have very good references for my work and myself interviewed so many people, but for this big company this type of interviewing style would limit innovative people from joining the team.
The person who interviewed seems like a junior person with very bad person skills. Perhaps, Netapp is not serious about filling up this role as they seem to advertise this from long time and with this kinda interviewing -- good luck with that!
