Gradiant Manager Legal interview questions

The interview went very smoothly. I got positive feedback. However, they asked me to wait so they could interview other candidates, as per their process. They kept me waiting for three months and never got back. I understand if a candidate is not a good fit, as I have been on the hiring end of the table. But keeping them waiting without proper communication is a bit arrogant. HRs should understand that it's only a two-way street, both the employee and the employer benefit.
