AIRMESH interview questions

It consisted of 3 round of interviews. First was a call from their Deputy Manager of HR and later the same person took a Skype Interview. A few days later another person took a telephonic interview which lasted a freakin 58 mins straight (which they promised won't be above 30 mins). The problem here is that after wasting so much of my time and taking so many rounds of interviews, no one had the guts to reply me or at least share an update as to whether or not I am in or out. If that's how they work with zero accountability, it's better that I didn't get to work with them. I understand that at some point they might have felt that I am not the one they're looking for but how long does it take for someone from HR to tell you that? The worse part was, I asked for an update but they never had the guts to reply to me. I do not recommend anyone to go for Airmesh.
