Applied online. Heard back within days and the proceeded to schedule a phone interview. While scheduling a phone interview, I was quite generous with availability and gave six hour windows over the next few days. Despite that, they wanted a time slot half hour before. No big deal, after all...I'm the one interviewing who would like to work there. Except, they never called. Sent a follow up email half an hour later and never heard back. Atleast cancel or send a generic rejection email, so I know better than to waste my time.
