Phone screen with HR, technical screen with a hiring manager, then a 90 minute written test, and then a presentation/panel interview. First two stages were quite simple, the test was relatively straightforward, and the panel interview was surprisingly casual. The panel members were very nice - they were looking for holes in my armor, but not being confrontational about it. Had a great time talking individually to each one. Two weeks after the panel interview I received a cookie cutter rejection email. Aside from the lame ending it was overall a pretty good interview process, and educational too.

Multi step process 1) Recruiter / HR 2) Online Test 3)Hiring Mgr 4) Hiring Mgr + other team members 5) can be additional similar to 4 with higher manager - depends
