The interview process took a month. First round was a general screen. Second round was on my resume and interest in Medallia, with 1 over-the-envelope brain teaser. Third round was a hard skills challenge that had a spec'ing exercise and a statistics challenge. Final round at Palo Alto was fine except I didn't get to interview with the third guy. They are awfully busy, but they should respect every candidate's time too, and commit to the structure of the interview. I didn't get thru, and asked for feedback. Yeah right that will happen...and they're into feedback analytics. Interview feedback is key to every candidate and they should understand that.
