The process began with a recruiter phone screen. She was consistently 15-20 minutes late to our calls.

Next was a technical phone interview, and the caller was late again.

A week later, the recruiter followed up with an on-site date. They covered transport, hotel, and meals.

I then had three in-person interviews. Although lunch was promised and I was there all day, none was provided.

Another week later, the recruiter followed up to say they could not continue.

I do not understand the significant delays, especially since the recruiter had stated feedback would be ready the following day.
