Stryker Computer Engineering interview questions

The HR rep that I spoke with has been extremely unprofessional this entire time, and I am sick and tired of it. He contacted me because he saw my online application to set up a phone call. Asks me for my availability for the next two days, and I respond within 10 minutes of his email. He then proceeds to not respond again for two weeks. We play this game of email-tag just to set up an initial phone call for a month. Finally, the phone call happens, and it's quick and simple. He said for second round, they use Gallup, an external behavioral interview company, for a 1 hour behavioral interview. Cool. I do that process within 3 days of the initial phone call, and the guy said I should hear back within a few days about the third round. It's now been two and a half weeks since the second round, and I have sent two professionally worded emails already, asking about the status of my application. At this point, I have pretty much given up hope, but I am in awe at how unprofessional this phone-tag and email-tag has been. Unbelievable.
