I had the first phone interview with someone in the next company, then there was a second stage of a presentation analyzing data, which was a little time consuming. I successfully moved on to the third stage interview, which was with someone in the customer success department. I was successful and moved to the “final” stage with two Team leads in the company and this was in person. One month after, they never reached out with feedback if I was moving forward or not in the interview. Four stages of interview and they ghosted. Very terrible attitude, considering I spent my time going through all those stages and going to their office.
