On the phone, but was made aware that there are at least 3 more steps (1on1 and flying to HQ). Applied on their site, received an email asking for a phone screen. The screen went well, however, the interviewer was cold and sounded busy(or annoyed) and interested only in getting through it as fast as possible. The company seemed unorganized since he informed that he had to call me right after his monthly meeting back to back and has few more people to get through. didn't hear from them after that. After waiting for a month I sent them an email and got autoplay with denial "Thank you for your interest, unfortunately..." Very unprofessional to make people wait. that long, glad I didn't get the offer.
