I applied online. The process took 3 weeks. I interviewed at Registrat (Lexington, KY)
Interview
Overall the process is very standard and typical and could take a few weeks from the time you apply initially, to either an offer or a rejection. I would not say it is exceptionally lengthy compared to other CROs.
Interview questions [1]
