This is so true. Companies complain about not finding talent, but with this kind of behavior, it is understandable. Recruiters are just like that, they send you plenty of offers and do not even bother follow up. I got the silence treatment as we'll from Thomson Reuters for a golang developer position: 1: phone interview that goes well. 2: technical interview that goes very well. The guy is very excited and barely can hide it. 3: formal phone call for logistic details 4: silent

After 3 unanswered mails, I dropped it. And for the best. I then joined Docker, I do work with Golang and I have a lot of fun.

It is not the first time this kind of thing happen and it is very frustrating. I think it just filter companies where you do not want to go work.
