Several interviews with HR, Hiring Manager and other members of the team in a span of 2 months. Around five interviews total, about an hour each. Constantly in contact with HR and Hiring Manger throughout the entire process. Led to believe that the interview process would continue and everything was on track. One full month later, received an automated email saying the position was filled. Hiring and interview process was fine until the end. Which seemed a bit unprofessional with the sudden cut off in communication and zero feedback. Invested a lot of time interviewing.
