This was a lengthy interview process.
1. Phone interview
2. Zoom interview (Introduction with 2 employees)
3. Case study
4. Panel Interview (Talk about Case Study and Skills with 4-5 employees)
Episcopal Community Services told me that they will contact me if I will receive the job offer or not on a specific day. I did not hear back and decided to contact them through email, and phone. Unfortunately, they did not send a response. I would expect at least an automatic rejection email for the time and effort.
Unfortunately, there are companies to ask for potential analysts to do these case studies. As I network with other analysts, there are rumors that these case studies are another term for "free work." So, please be wary before interviewing.
