Completely unprofessional.
After completing the screening with their HR representative I met with their CCO and then a number of other folks across capabilities and eventually the President of the Agency. All in all it was probably about 6 total hours of interviews across a number of days.
After I was told that they were still interviewing a couple of other candidates. I was completely ghosted. Nothing. No follow up saying that they decided to go with another candidate, just a complete lack of communication.
I was shocked that an agency that seemed to have it's stuff together, brought me through a rather laborious interview process, and had dedicated HR/recruiting staff who's job it is to handle this type of communication couldn't even respond to a candidate to tell them that they were no longer being considered.
Luckily, I think I might have dodged a bullet either way. If their interview process is this unprofessional I shudder to think how they conduct their business.
Prospective employees and future Clients beware. If they don't have the common decency to effectively communicate with candidates, what will they do to you?
