1. Email by HR upon applying 2. They will send you test quiz using SAS if you agree to complete in two weeks 3. Telephonic interview if you meet their criteria or rejection

I applied through a referral link and was given a journal article to read and respond to a few written questions about, a dataset to conduct descriptive analysis in R, and a proofreading assessment. HR told me that they are experiencing delays in processing/interviews and told me to wait an extra week. I followed up 2 weeks later and HR told me they would have a decision to me in a week. It has been 2 months and it has been radio silence. It is also important to note that you can only apply to one job at Costello at a time - HR had me choose between 2 jobs when I had already spent time completing assessments for both jobs.
