I've dealt with both internal corporate recruiters and external (headhunters) and I continue to be amazed at how awful they are as a rule.
I applied to a super regional bank, a recruiter reached out with some questions and stated that after I filled it out they'd reach out to set up a time to speak. Sent it back they responded positively and then radio silence, I followed up a week later then two weeks after that, radio silence. When I lateraled to my current firm, had the same issue with the same recruiter at that super regional firm.
I have had recruiters reach out for roles that have been awful matches either way too senior (Sr. Relationship Manager with 15+ years experience) or way too junior (temp to perm business analyst). What is wrong with these people and how do you deal when they go radio silent?
