Most likely others who they planned to interview dropped out and they needed another candidate, so you made it above the linewolf30 wrote: ↑ I applied to a job about a week ago. A few days later I received an email from the HR manager at that company asking me when would be a convenient time to schedule an interview which I promptly responded back. Unfortunately I didn't hear back at all from them for 3 days so I sent them a follow up email saying I was following up with them. When I woke up, I checked my email and noticed they had emailed me really early in the morning asking if I was available to interview in an hour's time. Like seriously?, how am I supposed to get ready and drive all the way to their office in an hour? I thought it was pretty unprofessional of the HR manager to do this. In all of my previous interviews, I never had an hr person suggest I come in an hour after they had emailed me. Most typically offer a few days time so that I could get ready.
This is to ensure they don't just interview too few candidates for the position.
