NetApp Support Account Manager interview questions

Interview process is very slow. It took almost 3 months to get an offer. Only thing the progress of interview and releasing offer letter need to improve. Lack in communication with HR after the process.

Initially, there's a 2-part interview with a multi-person panel, consisting of a technical session (lasting 1/2 hr) & an account management session (also lasting a 1/2 hr). The follow-up interviews were with the hiring manager, then program manager, and then the district sales manager. I was asked to white-board an example, as well as illustrate the OSI model.
