I was referred, received a call from UK to talk about office location, visas etc. All OK. I was told I'd be contacted about next interview. 2 weeks passed, I was e-mailed from Do No Reply e-mail address saying "Thank you for taking the time to come in and meet with us." despite never doing an interview with them. Not sure if I made it past any stage or if I was indeed supposed to do first round interview. Poor communication but friendly.
