First contact was over email, with a written PM challenge. After completing that, I had a 1 hr call with a PM, asking about my previous experience, as well as the question below. Next, the recruiter said I would have a call with another PM, but cancelled that a week later as they gave someone else the offer. This was pretty frustrating because I replied within 4-5 hours of every email I received, and gave virtually 24/7 availability for each interview, so I found it confusing as to why someone had cleared the onsite interview before I even got to complete my second phone interview.
