I applied online. The process took 3 weeks. I interviewed at Qumulo (Seattle, WA) in Feb 2015
Interview
A regular interview process for non-local applicants, first a phone conversation with recruiter with some questions on personal preference, then two technical phone screens, both with coding questions. Finally an on-site interview in Seattle office with five rounds of individual interviews, mostly coding questions. Engineers and the recruiter were very enthusiastic and friendly, and recruiter responded pretty fast on the decision of every step ever since my application was submitted. A very positive interview experience although I didn't get an offer.
