I was contacted by a Qumulo recruiter via LinkedIn. They were very excited about what I had on my resume. My experience with building engineered systems for customers was an area of interest so a phone interview with who I presume was supposed to be the manager or director of the group was scheduled. The first call attempt no one called me and I was told they had the wrong phone number (even though it was in my email signature and on my resume). So the call was rescheduled for the following week. The day before the scheduled call I confirmed with the recruiter the day, time, and phone number to call me and it was confirmed. However, come around to when it was supposed to happen I did not get a call as was scheduled. So, twice my time was wasted.
