EMSL Analytical interview questions

I applied online in May. Was contacted by HR a few weeks later to schedule a phone screening. The screening was very robotic on the HR representative's part. The same day I was scheduled to go on site the next week. Met with two managers in a fairly short and underwhelming interview, followed by a scheduled tour of the facility. They said they would forward my paperwork to corporate headquarters, which I should expect to hear back from. From that point forward, never heard back from their corporate headquarters, despite periodically attempt reaching out to them, with no response whatsoever. Only when I called the local site (which was hiring) in early September did I find out they hired others, and felt bad that corporate HQ never officially got back to me. Since then I have gotten another relevant job, but nonetheless very discourteous HR department.
