Application

I applied online. The process took 2 days. I interviewed at NetApp (Waltham, MA).

Interview

I applied online and I got the call for phone interview. The phone interview was a techinical round. It focused heavily on the data structures and heavily on API questions. Although its a sr. level role the questions were framed for college level schools.
