Allied Benefit Systems interview questions

It was easy to book an interview, it was via email. However, this company ghosted me after saying “it’s probably going to be a yes, I’ll contact you by tomorrow”…which seems to be a common theme upon researching.

I interviewed on a Tuesday and was told I would hear back by Thursday or Friday of that week, but NO LATER than that Friday. Well it's been over 3 weeks and I never heard from them again. I went onto their website to look at their openings and the job I interviewed for had been taken down. Advice to management and the talent acquisition staff... work on your communication skills with potential candidates, especially the ones who have already taken time out of their day to interview with you. Do not just ghost them. If a position they interviewed for has been filled, then be professional and at least send them an email. It's common courtesy. DO NOT say "you will hear from us by -" and then never communicate again.
