Phone interview followed by a series of very positive in-person interviews. I was very well qualified for the position. After interviews with program team, HR, and others, all of which went well, I was then kept waiting for more than four weeks before I gave up hope. Repeated (though reasonable) attempts to contact the hiring manager for an update were met with silence. Never heard anything concrete and I've since gone elsewhere. I was extremely put off by how the whole thing was handled. Extremely unprofessional. If that's how they treat potential employees, I'd hate to be an actual employee.
