Telephone interview with HR, followed by a video interview with the hiring manager. Then there was a joint video interview with multiple team members. Thought that the interview process was over, but then was asked to have an in person interview with someone else. Once that was done, again assumed that would be it. But no, another in person interview was requested, this time with the hiring manager's boss. After multiple attempts to follow-up, finally had a brief discussion with the hiring manager who promised to get back to me the following week. Then was completely ghosted until over a month later getting an auto-response "thanking me for my application" but they are moving forward with others. Completely unprofessional.

2 Step process - First interview with Directors from same department but different specialty/function, second was the hiring manager. Great interview with each for 1/2 hr and went well. Definitely a easy process and timely.
