Quest Diagnostics interview questions

First it started with a phone interview. A few days later I received a 1:1 interview with the Lab Manager. During the interview, I was asked some very basic questions and I was given a tour of the lab. The lab manager was very nice and accommodating. I asked the lab manager if this position required you to be certified because it did not say in the job description and their response was No, and there are a few employee's who are not. I asked when I would know a decision and that they would respond with in a week or so. I sent a thank you for the interview on Tuesday, which my interview was on a Friday, and waited to hear from Quest. The following Monday, I sent another email to the hiring manager for a follow up and she responded saying "unfortunately the position needs certification."
