I applied online. The process took 4 weeks. I interviewed at ATCC in Apr 2025
Interview
The process was straightforward. I had never experienced a 5 minute "interview". It was similar to a phone screening. I was originally rejected; However, I was re-interviewed at a later date and offered a position. My second interview I was able to ask questions and had more information on the actual position, so I was able to cater my responses to the questions.
