I worked at NII Holdings full-time (More than 3 years)
Great Telecom company, diverse workforce, focused on Latin America. Mobile telephony
no longer in business. The business was broken up and sold to various companies in South America.
I applied online. I interviewed at NII Holdings (Reston, VA).
Applied online and got a phone interview. I then travelled to Reston where I interviewed with 6 people - VPs, hiring manager and would-be peers. The interviews went well and I had positive experiences with several of the interviewers. The hiring manager gave me a date when they would get back with a response. Come the date, no email phone call or anything. I gave them a couple of days and then called, no answer from the hiring manager. I left a voicemail. I called again several times and sent emails since I had another offer that was expiring and needed to decide ASAP. However, they completely left me in the dark and never sent me an accept or decline.
Considering this was a mid management position reporting to a VP, I find this to be extremely unprofessional. Also having invested time, money and effort to travel to Virginia for the interviews, I expected much more professional behaviour. The worst they could have done was to have HR send me one of those "We regret to inform you" emails.
