The phone interview was casual and much more behavioral than technical. At the end of the conversation, they informed me they would get back to me later this week/ early next week to schedule a second group interview. After a week, I followed up. Quick, friendly response back saying: "its taking a little longer than expected to proceed, we will be in touch soon." Sounds good. I then continue to follow up once a week to check on the status and always receive a response like "sorry for the delay, and looking forward to continuing our conversations soon..." Well this back and forth went on for a MONTH until I sent a final follow up and they basically went sorry we kept you waiting and we are going to decline. Not a problem that you aren't interested, but a MONTH between phone interview and finally deciding to decline is not professional. Nice people, poor hiring process.
