Tango Software Engineer interview questions

I was contacted by a recruiter from HR to set up an initial 30 minute phone screening. This was basically just an introductory call where I gave some more background information and the recruiter gave me more information about the company. The call went fine and the recruiter was very personable and nice. He asked me to email him about my availability for the next technical interview with an engineer. I sent the email with my availability and never got a response. I sent 2-3 follow-up emails, but was completely ghosted. I was very disappointed by this kind of approach that Tango Card took to reject my candidacy. I understand that the role might've gotten filled so they rejected me before any kind of technical interview, but I would have appreciated any kind of response. Waste of candidate's time and disrespectful.

A time was set up to have a preliminary discussion. There was no call at the given time or email sent. Was ghosted. It's disrespectful and a waste of the candidate's time.
